@weld.com it would be great to see some stainless oxy acetalyne welding. I've been attempting a exhaust project. Using oxy acetalyne because that's what I own. There's surprisingly few videos showing stainless welds. Would be nice to hear opinions on flux for back of weld, or I've heard carbon rich flame works? (not tried this yet)
I learned Oxy/ace welding from an old mechanic when I was in my late teens about 50 years ago. He was in his 60s. He had made many of his tools by hand and hammer on a anvil. He said oxy/ace was all they had when he started and if you could weld with gas you could use anything. At that time there was no MIG or TIG. I watched him oxy-ace weld an engine cylinder back together bore it, hone it and polish it. Then he put the engine back together and it ran for years just fine. He was the chief mechanic at the shop. After a few more years he lost his eye sight but he kept right on working telling us what to do. Trucks came in and drivers told him what the truck was doing or not doing. He told us what to look at. He had the patients of a saint. I wonder how many guys he taught. I did a lot things with out a clue and was amazed when it was finished.
Both TIG and MIG were well established technologies by the 1940’s…..Gas welding and brazing have never been surpassed in practicality and likely never will…
@@jasonmcmanus6169 ohhhh yeah. I am 35 and guys my age look at a carburetor as if it was some ancient half mystical object. Working on this new electronic crap and working on a carbureted vehicle are like night and day. I can do both. But I am more and more not interested in being a mechanic because I do not like this new junk. I like the old ways. Who I am inside fit with how things were. Working on old stuff it's almost like an art form. You have to use all your senses and your 6th sense even. And you used your skills and brains. (And body!). I always liked the more physical part of just manhandling metal. I also love to tune and adjust the many things necessary to make old engines run perfect. It's all subtle and every tiny thing makes a change or difference.
@@jasonmcmanus6169 mate, You can't stop progress. You shouldn't matter if something new or old, just what best fits your needs. If some method is old _and_ it ain't the best at what it does, ditch and don't feel bad about it. There was a time when O/A was the new technology and maybe some blacksmiths didn't like it compared to forge welding, but it serves it's purposes.
I'm 26 and at 23 I got into welding after I realized I didn't wanna sit behind a computer, doing graphic design the rest of my career. However all the mig & stick classes were filled at school. So fortunate this happened, I took a metal sculpture class and constantly practiced with gas. Now I'm building truck bumpers with majority of the work being done with oxy. All of my long, hot hours and singed gloves have really made for some sexy fabrication I can't get with a machine. Here's to resurrecting the old school
Old school or not, oxy acetylene welding works. On the farm, I am not going to spring for a gas powered stick welder when I can load up the gas rig and go knock out a job. For the occasional job away from the shop on the farm, the gas rig works perfectly. It might be slow, but for non production jobs, it is an economical welding option that is independent of power supplies. Battery powered drill with a cup brush to clean the metal and you are ready to weld.
This. People think you need to spend 2-3 grand to get a good welder. My oxy setup was only about $750 (with a few different tips). 40lb acetalyne tank and matching o2 (don't remember cybic ft off the top of my head...). For me, as an occasional welder who will weld .25 material or less it does just fine. I'm just starting out in with my home shop and my welding setup does more than just weld. Stuck bolt? Grab the torch for some good ole heat and beat. Need to cut that? Well today I'd probably use my portaband but if it is bigger I'll put the cutting tip on. Even my small cutting tip will go up to 3/8. Oh! And no electrical work to get it running as mentioned! Handy when I was still renting... The old man loaned me his Lincoln buzzbox he bought new in the 80s, I think that thing has everything else covered. Really the only thing I'd say you need tig for is if you weld A LOT.
When I learnt to weld in the early 1970's, Gas welding is what was taught first, the instructor said that if you learnt gas welding other types of welding would be easier to learn later. I was taught that when setting the gap to leave one end between half and one thickness wider make the first tack at the narrow end and the other end will close to pretty well the correct gap.. I did not get to use a tig welder until the late 80's and due to the gas experiance I pretty well just picked up the tig torch and away I went near perfect tig weld first time so the instructor was correct.
@@Frank-Thoresen the thing I personaly find easier about TIG, you are more comfortable welding and are in control of everything, despite both torches are quite heavy because of the hoses and wires, there is no strong gas flux everything is very clean, far less heat, yoy can feed the rod at much smaler distance without geting burned and this allows better control of the rod, the puddle is formed instantly and is easy to manipulate, you can stop whenever you want and restart where you have finished instantly, all these things for me makes TIG easier the only thing about Oyeacetylene that is easier is that distance between the flame and puddle may be alternated without big consequences unlike TIG where professionals who have been welding for 10 years and over constantly dip tungsten into that puddle.
Well Well Well! If anyone who wanted to know how it's done doesn't know after watching this video then that person is never going to know. So much hidden wisdom given almost as an aside like "always use pliers - don't burn your gloves up!" In Robert M Persig's "Zen and the Art of Motorcycle Maintenance" there is a passage where he describes an elderly gentleman repairing a cracked chain guard off the motorcycle in the story. I remember reading that 30 years ago and thinking "I'm going to learn to do that". Well, I've eventually got all the kit together (albeit of hobbyist quality) and I have a cracked wheelbarrow that needs attention, so this video removes my last excuse remaining... Well done Mancub Sir. Whoever taught you, he was lucky to have a fine learner. You done a great job passing it on. Thank you all.
The pop is caused by one of your sparklers getting up in the tip. The sparklers, in turn, are caused by a flame that is a bit oxidizing at the outer edge. "Traditional" gas welding teaches you to use a neutral flame, but that is actually a bad idea. Neutral flames are always a bit O2 rich at the outer edges. Also, most rigs use single stage regulators, and as the O2 cylinder pressure falls the outlet pressure creeps up, making the flame even more oxidizing. Ideally, you should use 2-stage regulators for gas welding, but when gas welding went out of fashion so did 2-stage regulators. The best practice, whether using a single-stage or 2-stage regulator, is to use a slightly carburizing flame. Say, 1:1 inner cone to acetylene feather length. This won't make the flame rich enough in carbon to substantially carburize the steel, but it will keep the sparkly show down as well as giving you indication (by the constant appearance of a slight acetylene feather) that your flame hasn't drifted into an oxidizing condition. Another tip: For gas welding thinner material, say 1/4" or less, you will find that an aircraft-style torch with 3/16" hoses is much more comfortable. It's about as close to TIG as you will get with OA. My favorite is the older cylindrical-body Purox W-200, but they have been out of production for many years. If you can find one along with a good assortment of genuine Purox tips, they are great little torches. The forged-body W-200's that were made up until 10 or so years ago were too heavy for prolonged off-hand welding sessions IMO, but their extreme ruggedness made them superb field torches for the HVAC trade. My #2 choice would be the Smith "Airline" AW1A, which is very similar to the Purox and has the advantage of A: Still being in production and B: Still being made in the USA. Another one that is also very similar to the Purox is the Harris 15, which is also a nice little torch, although no longer made in the USA. Finally, there is the Victor J-28. I have never been a huge Victor fan, but they were fine until production got moved to Mexico. Now, quality has gone down, IMO. The one positive attribute is the popularity (which is also a negative, because it has pushed many far better torches out of production), and because of this popularity there are many clones available. Most are China/Taiwanese, but a couple are USA made. One is the Uniweld 71, which looks like the Purox W-200 or Harris 15, but it accepts all Victor J-28 welding tips. Of course, Uniweld makes welding tips for the 71/J-28 as well, not to mention specialty brazing tips for the HVAC trade. If I were in the market for a Victor J-28 compatible torch, the Uniweld would be the one I would probably select. If I were in the market for a new aircraft-type OAC welding torch, I'd go with the Smith AW1A.
@@infinityphotorob The welds will look the same or better. As long as there isnt too much feather, strength and toughness will be equal or better as well.
I learned oxy-ac welding in high school 84-86. i was weld slow but my machine shop teacher was hot and fast. i've welded 2stroke motorcycle pipes with a cutting tip (all he had at the time )and a clothes hanger in my friends garage back then. what ever works for you but learn them both, slow and fast. cool video.
I work in the repair shop at a cement plant. I pull out the oxy acetylene rig when all the welders are being used. My boss always staring at me like show off
@@Welddotcom Not completely lost yet and more folks know now because of this video (sharing, btw) and you've got me thinking about upping our portable oxy rig.
@@Welddotcom Maybe a skill that has gone out of fashion but there are folk like me (53 and still looking to learn more) that want to to learn and videos like these really help. Thanks go to Weld.com for bringing welding skills educational tips by video to the world!
A tip I discovered using the 3/32 wire is to lay it flat and hold it just above the weld puddle and weave the torch from either side of the filler rod and let the filler drop down onto the weld puddle. It makes oddball angles easier to weld in. I enjoy gas welding because if you can master gas, tig becomes REAL easy and there are time when gas can blend a weld in easier than even tig can such as on thin sheetmetal. Tig will leave you with a great joint but a bunch of material to grind down but gas tends to spread the weld out leaving a smother joint and less to have to grind back. Disadvantage is it creates a large heat effected zone meaning the metal will try and pull around on you if you don't plan for it. Great vid and hope it turns some folks on to the old school way to weld.
The “pop” at 3:35 or so may have occurred because your torch tip contacted the molten metal surface. I have been “old-school” oxy-acetylene welding for 40 years. I believe that extending your blue (oxy) flame tip another 1/8 of an inch would provide a helpful margin of error and reduce the possibility of overheating. Thank you for an informative, instructive video. And, thanks for verifying that the OLD SCHOOL IS NOT DEAD! Lol.
DANZ I’m planning to repair a cracked frame on a boat trailer. My stick welding is pretty poor, and I think I can do a better job with a torch. Plan B is to bolt some angle iron over the cracked rear corner welds. Plan C is to take it to a professional!
@@firstmkb best thing i did was a college welding course. It was 1 night a week over 12 weeks. From stick to mig to tig. Try find a community type college.
When I first got in the fitters the old timers still used oxy-act on 2 in and under, big tip lots of heat fast moving. much faster than arc and great looking welds
I took the combo welding program at Hobart. I believe first class was blueprint and then oxy-fuel and-built a coupon carrier using oxy-fuel. I’m still welding everyday. I build stainless steel exhaust systems and down pipes for an aftermarket Mercedes Benz company. Still love to weld.
@@jacklandismcgowan1413 That's awesome . That's exactly right. I should have said first hands on class. lol. Yeah i also took the Structural/Pipe program it was 9 months long. Ernie was my teacher for oxy-fuel and some other classes. Smart/calm old guy. He had a 55 chevy. He retired shorlty after i graduated in 2009.
Michael Becher Keep it up bro, definitely takes balls. So many internet experts. They think because they’ve read the process that they can do it. I’m here because I wanted to see how it works. Can I use 70s 6 filler rod on mild steel?
I learned to acetylene weld almost 50 years ago.. We learned fusion welding, welding with filler, etc.. I have used it for many years.. One thing I use to do is weld old wire rope to new wire rope to reeve boom lines on cranes. There was no load on the weld as it just pulled the new rope through all the sheaves (12 parts) and when the new line appeared, we would make it up and the job was done.. I used #9 tie wire as filler and always used Victor torch.. Mike in Louisiana
@@blackwaterrepair10 My wife bitched me out for digging all her old wire coat hangers out of the trash.. She likes the plastic ones ..lol.. NEVER but NEVER throw away wire coat hangers!
That has always been the go to method for all us mechanics except when some good buddy tries to help you out and pulls the old cable out first LOL I'm sure you've been there a time or two
It was nice seeing this kind of welding again. I used to work for a CNC router manufacturer where we had machines with aluminum vacuum bed tables for mounting the work. From cast aluminum plate to mounted on the machine and squared to the cutting head took over 24 man/machine hours. My coworker crashed the head into the machine and tried to fix a 1/2" deep x 1/2" hole using a MiG but only made a porous mess. The chief welder of the plant had us mill a larger hole in a cone shape and he used oxy fuel to repair the defect. The repair managed not to warp the top plate where the defect was repaired despite it's thickness only being .7". I remember machining less than .015" before the mill was scratching the rest of the bed.
I learned how to do this back in the early 80's. This was an easy way to connect new exhaust pipes on my 73 Charger. The hardest thing is getting use to the torch weight. My dad would use coat hangers, amazing!
No matter how experienced you are, you learn something from every welding video you watch, especially from other people's stuff ups. Stick welding (late 1800s) actually preceded gas (1903) welding.
I wish welding programs would still teach this. Yes, it's obsolete , but imo it's the best initiation to welding you can get(instant feedback on what you're doing wrong/right)
I Work in Germany for A Heating/Plumbing Company and we Use Oxy Acetylene to weld all of the heating pipes for the buildings we are constructing. I've welded miles of pipe already and also all the heating pipes running to each apartment for floor heating. Germany uses the old school boiler room setup with radiators in the apartments but all modernized. when I construct the boiler room in the basement i have to weld using the right welding technique unlike the Left welding technique done in the video.
I'm a gas welder at a gas utility company in Oregon. I gas weld up to 2" pipe. My test is a 3/4x1" branch and a 2" buttweld uphill. Out in the field we do 1" and 2" butt welds and 1/2" to 1" gas service tee's on 1" to 2" mains as well as 1" and 2" half line stoppers, all on live gas. As far as oxywelding on live natural gas lines, you are constantly on the verge of burning through. I could gas weld plate with my eyes closed.
Back in the day we did all our race car exhausts like this and with coat hangers for filler now u can't use coat hangers there nothing but slobber and slag but also this new exhaust pipe has so many impuritys and galvanizing that you can't hardly even mig it
My school has a welding program and in the first class (of 3) you learn stick, oxy cutting, and oxy welding, then you go on to mig, then flux cored and tig
I don’t like Oxy acet, and I don’t have to do it, but I like watching man cub. He doesn’t get enough air time. Maybe sometime you can graduate him to his real name.
I haven't oxy-acetalene welded in years. In fact, since High School for Ag class. I use them for cutting now though. I currently have a Miller/Smith heavy duty combination torch personality. Don't have a welding tip yet though.
Really cool to see a back to basic welding video.... one that doesn't use a tig welder with 75 different settings! Balance, pulse rate, freq... and so on. Well done!!
Why not have a look at some local trade schools or adult education centers. A lot will have welding classes go enjoy some evening classes. Also, Groupon has weird classes for cheap. We went glass blowing for $50ish
Nice job Oxy-Fuel Welding. I have used the torch almost 60 years to do most of my welding. I would like to see some demos on but welding some 19 and 22 gauge cold roil steel and some 3003 H14 0.50 - 0.62 aluminum. This is the material I have to work with every day in auto body restoration, custom work. The mig makes the welds to large and to hard to work. That is why I use the Oxy-Fuel for welding.
Taking a welding class in high school and we are gonna learn to do oxy/ace welding, I’m watching videos seeing how people do it so I have a good idea on what to do to impress chief with my welds.
The welding class I had when going to school to become a Diesel Technician Oxy / Acetyine welding was the first process we were taught tollowed by stick welding and then mig welding. We didn't get a chance to spend much time with Tig welding but it was only a six week course.
Great video. I always love to see oxy/fuel welding any chance I get. I enjoy using this almost as much as tig. It keeps you in practice. Thank you. Dan
I use a 00 to fuse sheet metal for expansion chambers for two stroke racing engines. Run the flame down the joint almost tangent to the weld and dip the cone in frequently. For me it’s faster cleaner and easier than tig. Jeweler fine tips work great for fusing thin sheet metals.
I remember working at Mastco building drilling rigs, sometimes early early mornin, the power would go ou all over the place, we used our oxy acetylene toches on the carbonizing side of flame to light the shop every now and then, hitting the tip to get rid of carbon on a chunk of wood.... damn, ..... I have good memories of the possibility of going home those days... but the light was great.
When I was taught oxy acetylene pipe welding many years ago , flat , vertical up . Horizontal vertical. Butt, branch , also the leftward and rightward method, oh what fun , popping and banging, blowback, sparks in your ears , down your shirt and underwear, many a time you'd set your overalls on fire when you'd got into a comfortable position and didn't want to move , oh and the welding with a mirror when you couldn't see around the backside of a joint ,, all good fun .
Oh and the dreaded overhead , where you control the weld pool from falling on your head with the pressure and angle of the flame and placing the filler rod in at just the right angle and time, now that is a skill . 💥
The Mancub! Gotta love it. Only thing missing was the end of video flatulence! LOL. Not bad Cub, not bad at all! Now you need to find something that belongs to Uncle Bob and sabotage it! Oatmeal in his umbrella, Vaseline in his welding cap, etc. etc .etc.
@@Nate-uf3kw its a pretty easy cop out to say a welders on drugs lol but let’s be honest , if your a good welder chances are that your not used to making tutorial videos 🤷🏻♂️
Don’t leave a gap in the plates. Butt them up tight, then you can weld them and the only adjustment will be your depth of penetration which sets your travel speed. If you don’t have a puddle in three to five seconds, adjust your heat or get a different tip.
Great video. Bob would approve. Relax, your voice sounds nervous, but more time on camera will take care of that. Try holding the flame back a bit. You might get less sparks. Blacksmith knife makers say that those sparks mean that you are burning the blade.
Im also learning how weld with a torch right know in college welding class, missed the class last fall. Thats why i asked if you can weld aluminum with a torch
Stepping up to the plate Mancub... well done, would have liked to see you set up torch and regulators and pressure setting. Also explain carburizing, neutral,and oxidizing flames. Good to mention not using gloves to move hot stuff, drives me nuts to see others do that. Also the safety glasses info... best wishes, Paul in Orlando
Thanks for the feedback. We did another video specifically on setting up the system where we went over different flames. Be sure to check it out if interested.
I haven't don't this since high school 16 years ago. We had a contest to see who had the Strongest welds. The machine would pull the two pieces of metal apart until the weld broke and would show how many tons of force it took. I remember getting 2nd place in my class, but I don't remember the specifics of the test (how strong my weld was or anything like that)
Wow that is interesting. I don't gap my weld at all on thin steel like that. I would guess that I gas weld more than most hobby welders and I have a very different style to make that weld. I would like to see that weld on a fold over bend test. I think a lot of the backside penetration he thinks he is seeing is cold fall through material.
I will start by saying great video showing process of gas welding. This would have been an opportunity to go into depth why a neutral flame. Is there ever a need to setup oxygen flame, or a carbon flame? Maybe follow up for Mancub.😎
This process is great for blacksmithing and doing ornamental work. Also great for minor repairs and possibly auto body work if you don't have a tig set up. We were taught this in high school shop class. The biggest advantage is oxy fuel doesn't require electricity. But it's slow. I've heard you can't use propane to weld? Not hot enough? But I can make Damascus steel on my propane forge? What's up with that? I'm an amateur blade smith and blacksmith. My side job. Working to get my welding certifications.
Since you seem to have all kinds of new equipment coming to the shop regularly, how about showcasing the Cobra (Henrob) gas torch for one episode or more.

Replaced is the best
And it's actually fun to weld with gas and rod. 👌🏻

I have never been a huge Victor fan, but they were fine until production got moved to Mexico. Now, quality has gone down, IMO. The one positive attribute is the popularity (which is also a negative, because it has pushed many far better torches out of production), and because of this popularity there are many clones available. Most are China/Taiwanese, but a couple are USA made. One is the Uniweld 71, which looks like the Purox W-200 or Harris 15, but it accepts all Victor J-28 welding tips. Of course, Uniweld makes welding tips for the 71/J-28 as well, not to mention specialty brazing tips for the HVAC trade. If I were in the market for a Victor J-28 compatible torch, the Uniweld would be the one I would probably select. If I were in the market for a new aircraft-type OAC welding torch, I'd go with the Smith AW1A.
This is excellent advice.
I am going to try this with the flame adjustment with a little bit of feather and see how welds look.
@@infinityphotorob The welds will look the same or better. As long as there isnt too much feather, strength and toughness will be equal or better as well.
I love this process it's the first I learned when I was 15 and In community College I made a beautiful outside corner joint on 10 gauge steel.
Awesome job mancub! For not doing this "old" school process for about 10 years, looks pretty good to me.
Thanks
I learned oxy-ac welding in high school 84-86. i was weld slow but my machine shop teacher was hot and fast. i've welded 2stroke motorcycle pipes with a cutting tip (all he had at the time )and a clothes hanger in my friends garage back then. what ever works for you but learn them both, slow and fast. cool video.
I work in the repair shop at a cement plant. I pull out the oxy acetylene rig when all the welders are being used. My boss always staring at me like show off
It's a lost art 🔥
@@Welddotcom Not completely lost yet and more folks know now because of this video (sharing, btw) and you've got me thinking about upping our portable oxy rig.
@@jameswyatt1304 I am slowly building up kit so I can learn how to do it.
@@Welddotcom Maybe a skill that has gone out of fashion but there are folk like me (53 and still looking to learn more) that want to to learn and videos like these really help. Thanks go to Weld.com for bringing welding skills educational tips by video to the world!
First class in welding school was oxy welding. The overhead test was sketchy.
A tip I discovered using the 3/32 wire is to lay it flat and hold it just above the weld puddle and weave the torch from either side of the filler rod and let the filler drop down onto the weld puddle. It makes oddball angles easier to weld in. I enjoy gas welding because if you can master gas, tig becomes REAL easy and there are time when gas can blend a weld in easier than even tig can such as on thin sheetmetal. Tig will leave you with a great joint but a bunch of material to grind down but gas tends to spread the weld out leaving a smother joint and less to have to grind back. Disadvantage is it creates a large heat effected zone meaning the metal will try and pull around on you if you don't plan for it. Great vid and hope it turns some folks on to the old school way to weld.
The “pop” at 3:35 or so may have occurred because your torch tip contacted the molten metal surface. I have been “old-school” oxy-acetylene welding for 40 years. I believe that extending your blue (oxy) flame tip another 1/8 of an inch would provide a helpful margin of error and reduce the possibility of overheating.
Thank you for an informative, instructive video. And, thanks for verifying that the OLD SCHOOL IS NOT DEAD! Lol.
Just curious what type of things you weld with oxy acet??
DANZ I’m planning to repair a cracked frame on a boat trailer. My stick welding is pretty poor, and I think I can do a better job with a torch.
Plan B is to bolt some angle iron over the cracked rear corner welds.
Plan C is to take it to a professional!
@@firstmkb best thing i did was a college welding course. It was 1 night a week over 12 weeks. From stick to mig to tig. Try find a community type college.
The sound of it is very cool. The power of fire is allways mesmerising.
When I first got in the fitters the old timers still used oxy-act on 2 in and under, big tip lots of heat fast moving. much faster than arc and great looking welds
Learned Oxy-Fuel welding at Hobart School of Welding 28 years ago and still use it occasionally. Excellent video 👍👍👍
If I'm not mistaken that's where Mancub learned it as well.
Thats cool.. I love stories like these..That was my first class at Hobart.
I took the combo welding program at Hobart. I believe first class was blueprint and then oxy-fuel and-built a coupon carrier using oxy-fuel. I’m still welding everyday. I build stainless steel exhaust systems and down pipes for an aftermarket Mercedes Benz company. Still love to weld.
@@jacklandismcgowan1413 That's awesome . That's exactly right. I should have said first hands on class. lol. Yeah i also took the Structural/Pipe program it was 9 months long. Ernie was my teacher for oxy-fuel and some other classes. Smart/calm old guy. He had a 55 chevy. He retired shorlty after i graduated in 2009.
Man cub so nervous on camera. Don't worry, bud, we love you no matter what.
Lol.. thanks for the support. Actually that does help. Seriously thanks.
Michael Becher Keep it up bro, definitely takes balls. So many internet experts. They think because they’ve read the process that they can do it. I’m here because I wanted to see how it works.
Can I use 70s 6 filler rod on mild steel?
ManCub Welder I’m here because you have training and a level of experience I’ll never have. Relax, and be proud to show us what you know!
I learned to acetylene weld almost 50 years ago.. We learned fusion welding, welding with filler, etc.. I have used it for many years.. One thing I use to do is weld old wire rope to new wire rope to reeve boom lines on cranes. There was no load on the weld as it just pulled the new rope through all the sheaves (12 parts) and when the new line appeared, we would make it up and the job was done.. I used #9 tie wire as filler and always used Victor torch.. Mike in Louisiana
I used clothes hanger wire for that once. (It was an an emergency)
@@blackwaterrepair10 My wife bitched me out for digging all her old wire coat hangers out of the trash.. She likes the plastic ones ..lol.. NEVER but NEVER throw away wire coat hangers!
That has always been the go to method for all us mechanics except when some good buddy tries to help you out and pulls the old cable out first LOL I'm sure you've been there a time or two
@@edwardkawecki8101 Yep.. That is something that is best avoided for sure!
It was nice seeing this kind of welding again. I used to work for a CNC router manufacturer where we had machines with aluminum vacuum bed tables for mounting the work. From cast aluminum plate to mounted on the machine and squared to the cutting head took over 24 man/machine hours. My coworker crashed the head into the machine and tried to fix a 1/2" deep x 1/2" hole using a MiG but only made a porous mess. The chief welder of the plant had us mill a larger hole in a cone shape and he used oxy fuel to repair the defect. The repair managed not to warp the top plate where the defect was repaired despite it's thickness only being .7". I remember machining less than .015" before the mill was scratching the rest of the bed.
I started welding a year ago and this was what I first learned lol it helped a lit with tig in the future for sure !
I learned how to do this back in the early 80's. This was an easy way to connect new exhaust pipes on my 73 Charger. The hardest thing is getting use to the torch weight. My dad would use coat hangers, amazing!
this is my old bosses favorite way to weld, it was his go-to.
No matter how experienced you are, you learn something from every welding video you watch, especially from other people's stuff ups. Stick welding (late 1800s) actually preceded gas (1903) welding.
Great video it's good to know how to weld old school 👨🏭
Nice job mancub, easy to follow commentary. Nice job .com team
I wish welding programs would still teach this.
Yes, it's obsolete , but imo it's the best initiation to welding you can get(instant feedback on what you're doing wrong/right)
You learn not to put the tip in it to because the unexpected pops scare the hell out of you
Love the oxy fuel welding!
Way to go Cub. Nice vid on a worthy process that is too often overlooked. Keep it up. Your cameraguy did a great job too!
High quality video! I’m taking basic Oxy fuel welding and I honestly love it so far !
I Work in Germany for A Heating/Plumbing Company and we Use Oxy Acetylene to weld all of the heating pipes for the buildings we are constructing. I've welded miles of pipe already and also all the heating pipes running to each apartment for floor heating. Germany uses the old school boiler room setup with radiators in the apartments but all modernized. when I construct the boiler room in the basement i have to weld using the right welding technique unlike the Left welding technique done in the video.
I'm a gas welder at a gas utility company in Oregon. I gas weld up to 2" pipe. My test is a 3/4x1" branch and a 2" buttweld uphill. Out in the field we do 1" and 2" butt welds and 1/2" to 1" gas service tee's on 1" to 2" mains as well as 1" and 2" half line stoppers, all on live gas. As far as oxywelding on live natural gas lines, you are constantly on the verge of burning through. I could gas weld plate with my eyes closed.
Back in the day we did all our race car exhausts like this and with coat hangers for filler now u can't use coat hangers there nothing but slobber and slag but also this new exhaust pipe has so many impuritys and galvanizing that you can't hardly even mig it
My school has a welding program and in the first class (of 3) you learn stick, oxy cutting, and oxy welding, then you go on to mig, then flux cored and tig
I don’t like Oxy acet, and I don’t have to do it, but I like watching man cub. He doesn’t get enough air time. Maybe sometime you can graduate him to his real name.
I haven't oxy-acetalene welded in years. In fact, since High School for Ag class. I use them for cutting now though. I currently have a Miller/Smith heavy duty combination torch personality. Don't have a welding tip yet though.
Soon as you mention the name Victor I knew you were the man and you've got the knowledge good video thanks for posting
Quality equipment for sure 🔥🔥
Oxweld W-17 for me. 50 years and counting!
@@edwardkawecki8101 Me too Ed , Oxweld w300 as well , my father's teaching. He only would buy Oxweld an Purox
Great start mancub.
Can you imagine welding battleships like this !!!
Battleships were always stick welded
@@meow_bastard Or originally riveted.
wayne -O I use to weld battleships with stick those were fun bring back memories
Really cool to see a back to basic welding video.... one that doesn't use a tig welder with 75 different settings! Balance, pulse rate, freq... and so on. Well done!!
OA works particularly well on exhaust pipes. Makes a nice smooth weld in the inside.
My favourite discipline in weldeng by far and I never get a chance to do it... cool vid
Thanks for watching
Why not have a look at some local trade schools or adult education centers. A lot will have welding classes go enjoy some evening classes. Also, Groupon has weird classes for cheap. We went glass blowing for $50ish
Nice work. Old school!
I'm new to this and self tought,thanks for the "'keyhole" tip.
Good video mancub! Let's see some of that oxy welding on aluminum next!!
It's coming
Nice job Oxy-Fuel Welding.
I have used the torch almost 60 years to do most of my welding.
I would like to see some demos on but welding some 19 and 22 gauge cold roil steel and some 3003 H14 0.50 - 0.62 aluminum. This is the material I have to work with every day in auto body restoration, custom work. The mig makes the welds to large and to hard to work. That is why I use the Oxy-Fuel for welding.
If you're welding paper thin steel and aluminium , why the hell are you trying to mig it
That's what's tig for
Taking a welding class in high school and we are gonna learn to do oxy/ace welding, I’m watching videos seeing how people do it so I have a good idea on what to do to impress chief with my welds.
The welding class I had when going to school to become a Diesel Technician Oxy / Acetyine welding was the first process we were taught tollowed by stick welding and then mig welding. We didn't get a chance to spend much time with Tig welding but it was only a six week course.
Great video. I always love to see oxy/fuel welding any chance I get. I enjoy using this almost as much as tig. It keeps you in practice. Thank you. Dan
That's pretty cool! I hope I never have to resort to welding with that technique!
great work i practice this home many times mild steel aluminum and stainless steel i use a carburizing flame to weld stainless steel
Oxy-Acet welding stainless?🤔
That's what i use for welding gun-barrel pipework for heating systems here in Ireland
I use a 00 to fuse sheet metal for expansion chambers for two stroke racing engines. Run the flame down the joint almost tangent to the weld and dip the cone in frequently. For me it’s faster cleaner and easier than tig.
Jeweler fine tips work great for fusing thin sheet metals.
I remember working at Mastco building drilling rigs, sometimes early early mornin, the power would go ou all over the place, we used our oxy acetylene toches on the carbonizing side of flame to light the shop every now and then, hitting the tip to get rid of carbon on a chunk of wood.... damn, ..... I have good memories of the possibility of going home those days... but the light was great.
thank god for modern welders
When I was taught oxy acetylene pipe welding many years ago , flat , vertical up . Horizontal vertical. Butt, branch , also the leftward and rightward method, oh what fun , popping and banging, blowback, sparks in your ears , down your shirt and underwear, many a time you'd set your overalls on fire when you'd got into a comfortable position and didn't want to move , oh and the welding with a mirror when you couldn't see around the backside of a joint ,, all good fun .
Oh and the dreaded overhead , where you control the weld pool from falling on your head with the pressure and angle of the flame and placing the filler rod in at just the right angle and time, now that is a skill . 💥
top notch video of the welding
Thank you for this video.. it's little things like know how to hold the torch that help.
The Mancub! Gotta love it. Only thing missing was the end of video flatulence! LOL. Not bad Cub, not bad at all! Now you need to find something that belongs to Uncle Bob and sabotage it! Oatmeal in his umbrella, Vaseline in his welding cap, etc. etc .etc.
Thanks
calm down broski...you look extremely nervous in front of a camera.....breath!!!!
Cocaine's a hell of a drug
Thanks
Drugs
@@Nate-uf3kw its a pretty easy cop out to say a welders on drugs lol but let’s be honest , if your a good welder chances are that your not used to making tutorial videos 🤷🏻♂️
Oxy was the 1st class in the welding program at my HS/community college. Haven’t touch a torch in too many years. I need to get back to it
Don’t leave a gap in the plates. Butt them up tight, then you can weld them and the only adjustment will be your depth of penetration which sets your travel speed.
If you don’t have a puddle in three to five seconds, adjust your heat or get a different tip.
...and grind a bevel.
On 1/8” plate there is no need to bevel. If you can’t get full penetration on thin plate then adjust your heat and travel speed.
Great video. Bob would approve. Relax, your voice sounds nervous, but more time on camera will take care of that. Try holding the flame back a bit. You might get less sparks. Blacksmith knife makers say that those sparks mean that you are burning the blade.
Ok..Thank you sir for the tip.
Second thing I was taught was welding cast iron, got real good at it. Only to find out nobody ever uses it any more!
Nice job mancub!
That does not look easy, but boy does it look cool.
As Mr. Moffatt said. It's a good introduction to tig welding. Learning to manipulate the weld pool with the use of filler rod.
old school cool.
Im also learning how weld with a torch right know in college welding class, missed the class last fall. Thats why i asked if you can weld aluminum with a torch
These vids r def helpful i learned to weld using Oxy/Ace from these vids here
Excellent video and your welding skills are amazing. Thanks.
This is the first process I learned
Great procedures steps by steps, thank you
Stepping up to the plate Mancub... well done, would have liked to see you set up torch and regulators and pressure setting. Also explain carburizing, neutral,and oxidizing flames. Good to mention not using gloves to move hot stuff, drives me nuts to see others do that. Also the safety glasses info... best wishes, Paul in Orlando
Thanks for the feedback. We did another video specifically on setting up the system where we went over different flames. Be sure to check it out if interested.
@@Welddotcom outstanding guys...
Nice job there !!!!!
I haven't don't this since high school 16 years ago. We had a contest to see who had the Strongest welds. The machine would pull the two pieces of metal apart until the weld broke and would show how many tons of force it took. I remember getting 2nd place in my class, but I don't remember the specifics of the test (how strong my weld was or anything like that)
Just did this yesterday, love this channel so much if I'm not welding I'm watching these videos hahaha
There is a exhaust shop in Kentucky that welds with oxy
Got a couple gloves like that. Man I love 'me. Best gloves I ever bought
Thank god for technology!
Real men weld with oxy-acetylene.
Man Cub is doin lines in the bathroom again.... little bit of warm water up the snooter before you exit keeps the sniffles down
Thanks. Dang bronchitis
I knew a man that could weld a muffler the same way... didn't seem to matter how thin the steel was he could weld it
I'm just going to leave this time stamp here so I'll always know how to start.
4:40
This is a very enjoyable type of welding !. You can take your time, but at the same time keep your focus razor sharp ^^
Really enjoyed this one lots of good tips!!!!
Great video!
I'd like to some hardness testing and nital etching of the HAZ for an OxyFuel Weld! Some mechanical tests would be cool too.
Wow that is interesting. I don't gap my weld at all on thin steel like that. I would guess that I gas weld more than most hobby welders and I have a very different style to make that weld. I would like to see that weld on a fold over bend test. I think a lot of the backside penetration he thinks he is seeing is cold fall through material.
That's how i first welded back in 1980.
Very nice Viktor torch👑👍
City of Long Beach CA they gave a 4" pipe test with gas welding.You should do video with pipe.
We'll add it to the list
I will start by saying great video showing process of gas welding. This would have been an opportunity to go into depth why a neutral flame. Is there ever a need to setup oxygen flame, or a carbon flame? Maybe follow up for Mancub.😎
At The End , I Thought I Was Watching The " Red Green Show " Oh Geeze !!!!
This process is great for blacksmithing and doing ornamental work. Also great for minor repairs and possibly auto body work if you don't have a tig set up. We were taught this in high school shop class. The biggest advantage is oxy fuel doesn't require electricity. But it's slow. I've heard you can't use propane to weld? Not hot enough? But I can make Damascus steel on my propane forge? What's up with that? I'm an amateur blade smith and blacksmith. My side job. Working to get my welding certifications.
You should make another video but with aluminum!
Both my grandads where welders one taught the other. Both tho had a lot of health issues from it
Gorgeous weld ! I'm jealous :-)
Since you seem to have all kinds of new equipment coming to the shop regularly, how about showcasing the Cobra (Henrob) gas torch for one episode or more.
