I love the old school videos showing field or emergency repairs with limited tools. I would like to see videos showing use of carbon torches (both welding and cutting) and brazing of aluminum. I have heard that you can weld aluminum with them using the right flux. Cheers and thanks.
Just to clarify (I am not sure on the terms), when I say carbon welding, I meant using a twin carbon arc torch.
Which videos? please post a link as I see alot of this stuff in old PM magizines. Thanks.
i'm watching this for my welding class and his voice and the crackling of the torch is just, so, soothing, to the point where its hard not falling asleep.
As an A/C guy, I also enjoy brazing. This is not quite the same, as my brazing is non-ferrous, but that’s exactly why I’m here. I love your instructional videos! Thanks
I learned to braze almost 50 years ago and it is still a great way to repair broken cast iron..The problems people encounter usually stem from not cleaning properly, too much heat, not enough flux, etc.... Cheers; Mike in Louisiana
Bob, you made that braze look simple and clean. I think that if I practice about 47 bazillion hours, I might come close. Thanks for your excellent videos!
It doesn't take long to learn, but when you practice be CONSISTENT and practice the same joint until you're proficient, then perform other joints. Spend say an hour between breaks so you can work without interruption.
I learned brazing in High School, took me about a week to get good at it, maybe 5-6 hours total. If you've done regular oxy-acetylene welding, this is about like that but with less melting the steel.
Glad you still stress the basics which gas welding teaches. I'm almost sixty and my first welding class in high school was gas welding and I'm thankful I learned, it made learning all other welding process easier. I also still do repairs and some artistic projects with brazing and soldering, I find it calming.
I'm not quite as old as you, but I'm up there. The first welding process I learned was MIG, followed by TIG. The reason for that is that my father was a certified aircraft welder for the Air Force, and we had MIG and TIG equipment in the garage when I was a kid. He taught me gas welding later as a teenager, and I learned stick welding on my own with the help of a welding textbook. I eventually became certified for different processes and specifications myself even though I never really worked much in the trade. This was back in the day when any college or vocational welding course still started with gas welding, and wouldn't let you touch any electric welding equipment until you had passed your gas welding course.
While my situation was unusual, I am still of the opinion that a person should learn fundamental welding first using oxyacetylene. Compared to electric welding processes, OA is unparalleled for learning puddle and heat control and rod manipulation. It's also the most versatile process, since you can weld, braze, braze weld, solder (overkill, but it does the job) and heat metal for shaping or forging, and with the cutting attachment you can cut, gouge, bevel, etc. Even if you never weld with gas, no metal shop or hobbyist is complete without an OA outfit AND the skill to use it properly.
Of course, if you do have it, you should occasionally forego the MIG, TIG, or stick on a non-appearance-critical steel weldment and use the OA, just to stay in practice. If you stay proficient it will look good and be as strong as the parent metal, and you will actually enjoy the process and won't get an arc tan :)
agreed. I'm 48 in a couple of months. Learned weld as a kid pre-teen from Dad. Went on to be a welder/fabricator in the Army..years later 2012 to be exact . For chits and giggles decided to take a college course in welding from the Local community college. Imagine my surprise looked, when the 27 year old instructor informed me the first day of class. The only OxyAcy we use is a cutting torch. I do not teach gas welding of that type. No one uses it anymore. Later I was informed he was actually a machinist who lucked into the role of teacher. After that I informed the class one day of what they were being screwed on and I would spend time with them after class showing them the real basics of welding. I've asked the college why they allowed this..they never reply..Just saddens me. Promote this kids to exceed in welding.. yet they are taught very little. And the college wonders why they are not hired.
i had a similar exp's when it took a welding program in college,,the teacher (a scotish chap who worked for rolls royce jet engine mfg) told me they wont teach gas welding no more despite there being a few rigs in the class he said it was used by some guys in refrigeration or some other class and that teacher would be pissed if gas was low in the tanks,so i learned mig and stick first then tig where we moved from ms to ss but the sob teacher would not let me work on SS (or was it al?)because it was too costly and he was worried about having the school waste money buying more of it and affecting his class budget or whatever ,so instead he tried to cheat us with steel saying it was the same ,no one else noticed or asked despite us paying for a tig course in that specific material,so i went to the dept and complained and the very next day he gave me the material ,i think he knew i was the one who must have complained lol but seriously they only teach you safety,some basics on electricity with the machines and how to run the machines and basics in welding techniques and its mostly you on your own hands on ,no metallurgy science or nothing like the old days ,all that stuff you need to pick up on your own
Welding with a torch first is the best way because as I have seen it makes you more aware of heat transfer and what it takes to heat up metals.
Most of the places I have worked and most of the knucklehead welders I have worked with don't seem to pay any attention to heating of metal or heat flow or anything. They think just strike an arc on an ice cold heavy block of metal and everything will be fine.
Or lay down a nice fast cold MIG weld that you can peel up with a chisel.
AHH the great smell of brazing ,The oxy acetylene process/ brazing was the first welding process I learned in vo tech. Many people dont realize the incredible strength of brazing I remember brazing broken gear teeth that saved thousands of dollars. To replace the gear was over $2700 dollars and to repair it was about $20.... great job.
Yup. It's still the only process commonly used on saw blades. Have you see what a well made saw blade costs? Check out Forrest blades, they're the best made in America blades you can get and you pay for it, too! I was surprised to see even the diablo blade I bought from Freud for my sawzall even has brazed carbide teeth on it. She's an absolute beast with that blade on it!
Damn your right thinking about it. Never thought brazing was that strong
@@jamesavery6671 50,000psi typical, up to 65,000psi for a good braze weld with low fuming bronze. Silicon bronze and the aluminum bronzes are even stronger, but less ductile and shock resistant.
@ARCTURUS "...The oxy acetylene process/ brazing was the first welding process I learned in vo tech...." Same with my son. He did some very nice braze welds, as well as steel. When he got around to TIG welding, it was a cinch.
I learned more in 14.5 minutes here than I have in the last year trying to learn this through practice. Thank you so much!
Thanks for doing this video Bob. Haven't brazed in about a thousand years but can remember using it on a lot of things in the past and recall admiring how surprised I was at the strength of the bond. I hope the students attending your class realize how lucky they are to have someone like you teaching them.
Oxy acetylene, or gas welding and brazing is great! I learned it first along with cutting. Then I learned using propane. It is still my failsafe go to. I will never forget the comments the first time someone watched me literally weld a copper heat exchanger with gas. I use a lot of high tech today but still love old school gas.
Keep your great videos comming! You are doing the trade a great service by being a excellent teacher!
What is the difference with Propane? What pressures do you use for oxygen and propane, do you use the tip of the cone? Do you get more blackening of the tubes? Love the answers to those questions please.
Its such a pleasure to watch your videos. Its obvious that you are passionate about your trade and a great teacher. Thanks for doing what you do!
Started gas weldng/brazing this weekend. Your video has helped in knowing what I SHOULD be doing and what to expect when it is done correctly.
this guy is a great teacher. one detail for those who are interested - it is not capillary action that joins the surfaces, they join as a result of molecular interaction of the liquid metal with the solid metal, caused by wetting.
Genuinely love your guy's videos, old and new. Your use and expertise of not only the welding methods and knowledge but also the camera footage you provide makes it so much easier for me to learn how to do these processes myself. Thank you!
Thank you for showing us all how to make brazing happen. This was taught when I was in school metal shop. Some of the fondest time spent in shop class. Today they do not even have shop classes or even music class so i am told. Nicely done fella too.
Very enjoyable seeing little used techniques. I was taught at General Motors Fisher Body in NJ in 69 oxy acetylene wire weld and lead joints and using weld wire to make rivets on metal to join panels . I miss it and really enjoy seeing a welder doing his craft well. I am always telling young kids there is so much out there And it pays well and you have a nice product when you are done . Such a Blessing !Thanks you for providing Good resource.
So happy to see and hear someone still teaching base welding tech. Gas [oxy-act] along with brazing. Low Fuming Bronze brazing is what I learned first back in '75. Glad I rolled into your channel.
in school my old agg teacher was a retired pipeline welder this was my first weld he taught me
I truly dig this tutorial, it shows or teaches so much in such short time, the distance of the tip not being constant was the biggest tip I learned. I also watch your videos more than others because being left handed, I can mimic/ follow your movements easier. overall, everything makes more sense. thank you.
Bob. Thanks for this. Thanks for what you do here and how you teach. Your teaching style is nicely refined. Your knowledge and talent being shared is greatly appreciated by me and by many I'm sure.
This 60yo firefighter is learning a bunch from you.
I have a 1200 sq ft "man shed" that has just gained a budget arc welder. With your assistance, I am teaching myself how to weld and work with metal. Something I've always been interested in but never had the funds nor time to pursue.
Now? Bring it on, buddy. I'm ready.
Thanks for this. There are some of us who can't weld anymore because the welders can interfere with implanted pacemakers and defibulators. Yep, that's a thing.
That is how I learned. Bare P bronze with AntiBorax flux. Victor 100. The phosphor bronze rod is eutectic so once it reaches melting point, it flows like water. Also used food grade silver bearing for stainless matching. Still have that flux in my tool box.
My father in law restored his 1957 by brazing all the replacement panels in. We worked on an old 68 Chevelle we pulled out of the weeds and we started to strip the body. The quarter was replaced and at some point in the past, once we got down to the seam...by George it was brazed! Very very strong!
Learned braze welding in navy weld school years ago. We were taught a different technique that that leaves the bond looking like a really nice weld bead. I see that you pull the flame outward. What we were taught was more similar to SMAW with say a 6011 rod. The filler rod and the flame move back and forward together like a dance. We'd move the flame back (not out), bring the rod in and "dip," then move the flame and puddle forward. The rod always remaining in the flame envelop as well. A very intimate dance. In this way, the flame envelope seems to better prevent contamination and I found that it allows you to control the process better and without as much manipulation. It also seems faster to me. Like 6011, one might maneuver a bit side to side to wet in stubborn edge point, but generally a back and forth motion. We also got to do this in the over head position on . . . ahhhh! Cool video. Thanks
I took a welding class in adult education and loved it. Our class was divided in half...one side learned stick and Mig...the other oxyacetylene and stick. Unfortunately, I didn’t get the opportunity to learn the oxyacetylene because we ran out of time. I’m thinking of just going and buying a set and teach myself. Your vids help immensely!
Same technique for our shipboard repairs back in the 80's. Nice job.
It seems that if you'd have put higher heat into it, you would get partial drips on the other side. I appreciate the tight camera shots showing the technique.
Perhaps. Honestly I'm only familiar with copper and silver rods used for HVAC brazing.
The rods he,s using seems to be almost 40% zinc. Its practically brass.
It looks much less fluid than the silver rods used for brazing copper HVAC pipes.
Thank you for taking the time and effort to make an educative video in which we can learn the science behind “welding”. You show that it’s not just what you learned watching others weld but the fact that there is a science behind all. Thank you.
Brazing has a lot of haters in people who don't even know much about it. It's my go to. I've found it easy to learn, less distractions with no metal popping all over and just generally cleaner and less stressful to begin with. A lot of it is almost as strong and best of all it never rusts!
"pretty good size gap, if you can (say) see that on camera"
he said if you can see
Got my first welder for christmas and I am so excited to get fully into it
This is a really good skill to have under your belt as a welder. This was one of the first things I learned as a young kid with a full set of bottles and a butt load of time. I learned a skill and kept out of trouble at the same time. Idle hands being the devils workshop. Thanks for the look back.
When I still lived in England my home country I used to build race car chassis we used use sifbronze its a dying art great to see you doing this
Some of the best brazing I've seen in a while. Excellent technique and control. Thank you!
I just purchased some tanks and torches because of this awesome tutorial. Thanks for sharing
Very nice presentation! Excellent video recording! This takes me back about 40 years to auto body school and as you stated the progression of torch first and then wire welding MIG. I later in life learned silver brazing with 15% and 45% silver depending on the application. I cannot thank my junior year teacher for teaching us the techniques! (Never learned to TIG but assuming at 55 the need to learn is pretty low)
Amazing video. I watched a few videos earlier and they just didn't get quite in depth. And explain things like pressure or thickness of wire and such. THANK YOU!!!
What you are demonstrating is "Bronzewelding" Brazing involves a different joint design (lap/socket ) joint and a different composition filler metal (nearer the Eutectic).
Love this I still braze a good deal . Thank you for this video to refresh me with the basics.
I've just got into brazing. I am trying to braze some steel legs for a bench but the steel always gets covered in a black soot from the torch. Could anyone tell me what I'm doing wrong? Great video very helpful 👍
More oxygen
So good to see these videos, Bob! I learned these things in high-school and by teaching myself, and now that I'm retired, I'm picking them back up to keep busy, and fix things for family members.
Thanks again!
Good to hear.
If I were a plate of mild carbon steel with bad intent the LAST thing I'd want to do is cross paths with Bob Moffatt. Also: that weld is gorgeous. I never thought brazing would render such a clean result.
I have a table made out of 1" Sq tubing and it is all covered in brass made by the best weldor I ever met his work was amazing wish I had met him sooner
We'd love to see a picture. If you've got an Instagram or facebook account, do share! Be sure to tag us so we know to look.
The type of teacher teaching the kids chemical comp of metals before striking an arc.
I do silver solder for a living. I work with stainless,copper,brass.....sometimes all in the same part! I often wondered what more i could do with this skill? Doing something neat like this looks like a lot of fun!
Great Video. Shows how its done. Did a lot of Brazing in the late 60s, early 70s and then got away from it. It is like Tig and it looks so Pretty when your done.
2nd best channel to learn anything related to welding brazing soldering. Your students are lucky to have such a great teacher with a wealth of knowledge. Who is 1st.................😃
I have finally got of my ass to learn what the definition of “brazing “ actually is and was oh so fortunate to find your video. I know nothing about welding and am developing an interest to pursue it. You sir, are an excellent instructor. Wish I was in your area (wherever that is ) so that I could take a class from you. Excellent, comprehensive video. Thanks so much.
Great video. It’s nice to see a technique that can be utilized without using a lot of expensive equipment.
I use to deliver 1000 newspapers when i was 13 used to have 3 big bags hanging off me with multiple trips back home for refills my dad introduced me to the world of fabrication and we made a trailer all brazed together to go behind my bike to carry all my papers it was awesome!!
Good stuff! Are you still fabricating?
still fabricate none of my tickets are alive anymore majority of my time is spent designing.
1000 hunh? You would have needed that trailer. I delivered 350 on Sunday and when offered it had to turn down my 4th route because my dad didn't weld/braze. I'm forever designing things in my head, some make it to paper and even fewer to real life. I'd love to build a long electric trailer. Got some 20 bmx wheels & a black rooftop suv carrier made by Porsche. Not sure what motor/s to use. Would like to have it push me and camp out of it.
Some people watch basketball, baseball or football, but I could watch this stuff for hours. I might be building a Legal Eagle XL and brazing is the main method for connecting all the frame pieces together.
Good video. Here is one little tip for you. This works especially for lighter gage materials say 14 gage or 12 gage. Should work on any thickness though when brazing. To control the width of a brazing bead try using a No.2 pencil and mark out lines say 3/8" wide and run a bead inside the lines. The brazing material won't cross the pencil lead. Don't ask me why lol. An old timer taught me that 30 years ago. Helps make a nice straight bead. Try it out and let me know what you think. It should work for you.
So glad I bumbled upon this channel. I have been thinking of learning to do some basic welding, just hobby, decorative stuff. I have found good welders to be more $$$ than I can put out at this time. Brazing will do great to meet my needs. Thank you so much.
Believe it or not I learned about brazing in jr high shop class in the mid 80s. I don't know how many districts offer that sort of thing, but it seems rare nowadays. I didn't pick it up again until about 9-10 years ago when I got a hold of a torch rig as payment for moving my mother in law out of her house. (It was her late hubby's so she didn't need it) I have found brazing to be very useful in repairs and fabrication in my garage workshop. I've used it to repair a cast iron well pump and my shop vise. The pump repair outlasted the motor on the pump.😄 I also use it to join thin walled tubing when trying to weld it would just burn holes through it.
Great video. Really interesting to see some brazing being done. You did a great job of filming the molten puddle, very clear. It really helped in seeing what was going on. Thanks!
Good video. Very easy to listen to...no pointless rambling. Learned lots already....Thanks!!
Great close up of the flame and rod intersection!
Bob , You didn't mention flame control. When I was taught gas welding and brazing in my A&P course we were told that a 2X reducing flame should be used for most carbon steel brazing.
The AWS Brazing Handbook goes into flame adjustment for brazing in more detail.
This is very controversial! I think a slightly oxidizing flame can be used here, one of the few places it can be used. The FLUX is made of oxides, and the flame is contacting the flux and not the metals, we hope. Then there's fume control, the zinc in there vaporizes, burns, makes a kind of smoke which is unwholesome. You can do a little demo here if you turn the oxygen up and down, you'll get more smoke or less, like magic. I was confused about this for years! I think the big point here is that in brazing, what the TORCH sees is glass, not metal.
I like what you said, "When do we see braising projects? Never." I need to cut some 1/4 inch copper hose out of a proprietary brass fitting, and braise it to a normal propane fitting, and be assured it doesn't leak. I am now searching your videos.
Bob, you rock! Love watching your videos. Lots of variety from a guy who really knows his stuff. Keep up the great work.
Accetelye weld using can flux, and wire coat hangers !! On the farm when you ran out of bronze wire while cutting/harvesting you grabbed what you had !!
Someone should make a channel devoted to ultra low budget and low quality fabrication.
@@shawn576 I think Oxy/Acetylene would be out of the question then!
Oh so true!!! But it frustrates me today, although the hangers are much bigger around and you should be able to fill in a gab better, mine just keeps catching fire and making little black gnats and runs everywhere??? I don’t understand why hangers today just don’t work like they used to 😂😂😂
I appreciate your knowledge and how you show others the skill of brazing. Very informative .Thank You
That reminds me when I was young used to braise in patch panels
You are a wonderful teacher sir. Thank you! Do you always hold the torch in the left hand and manipulate the rod with your right? I’m right handed and feel more comfortable with the torch in my right and the rod in my left, but I’m not the greatest, so I was curious as to whether or not I’m selling myself short. Thank you again.
Ben Rifkin Wondered that myself!
Not an expert here but holding the rod with my dominant hand worked best for me.
Great method! I use it alot on exhaust manifolds insted of welding. Works great!!
In my two year course, I started with OAW, went to TIG, SMAW, then MIG.
This was everything I could have wanted in an instructional video sir. Thank you very much!
I've recently brazed about 4ft of 3/8OD 1/32" wall copper tube to 1/8" 304 with OxyHydrogen and Safety-silv 56% fluxed silver braze rod(orange). It was a real hoot. Took some technique and finessing. Had to set the torch just barely into oxidizing in order to heat the copper enough to wick the silver and had to constantly move the torch along the copper like a surgeon with a drinking problem.
It's basically, heat the tube, move the heat into the zone where you're working until it's orange and about to blast a hole, braze 3/8's with heat concentration more on the stainless while jumping up every now and then reminding the copper to stay hot, apply heat to length of copper again, come back to push and polish the puddle around, repeat. Then go back and fill where you didn't add enough!
The flux makes a mess, but after some glass chipping, wire wheeling, and scotch brite it sure is a pretty sight when done. This was for a heat sink application where both sides of the tube were brazed. Good times.
Great to see this, I still do quite a bit of gas brazing and always enjoy it
Where can I buy the tanks, hose etc?
My son was watching one of your vids with me. LOL... he said why do all the good welders seem so calm? Just like airline pilots I guess.. Doesn't help the situation if you panic. When I got my first Harley way back when and noticed everything was tube and socket and brazed. I was told the result was stronger than a weld
You always tell me exactly what I need to know just when I realise what I need to know.
I like the hand slide technique @7:14 lol. Awesome work, we're lucky to have your videos to learn
1:20 in the books it seems super intimidating thanks for breaking it down for beginners so well
thanks i learned oxy acetylene in high school ,long ago,now im a beekeeper and want to braze copper to make a oxalic acid vaporizor for mite treating hives,solder too low melting,so im going to try oxy / map little brazing kit,i like your explanations,soon im going to harbor freight for a tig set up, to compliment my mig,ill be following...
I love that you said you love brazing because I do to and you're a welder so that's even greater 😂👌🏼
very cool video~ just did some brazing to make a condensate pan at work for hvac job. While working at a body shop years ago seen the foreman do some brazing on a wrecked truck and I was amazed at how it looked just like a row of dimes from a tig weld . I have tried over and over but could never get that look of the row of dimes
My first brazing class for my apprenticeship is in 1 month. Time to learn.
Really enjoy your instructional techniques find them very informative . Keep up the great classes. Thanks
I worked for a gentleman that loved using a torch. he was amazing with it. so of course I was excited and not disappointed in this video. if you get a chance check his company out. it's TM technologies. I no longer work there but still love the idea of using the torch. it is amazing what you can do with a torch that most people don't know you can do. Love your video's. Maybe I'm a dork but I always look forward to what comes out
That's what we love to hear! Thanks for the support
Brings me back to vo tech class I wish I'd had stuck with it drywall know
Enjoy the lesson Sir! Thank you
I seal 6" lead tubes with 2' lead solder for underground cables. They need to be air tight.
Good penatration you have with that joint..nice. 840°
Let me add some detailed explanation on that "capilary action": yes, it is that "wicking action where a liquid flows by itself into narrow spaces" - providing that the liquid in question does "wet" the solid. Like, say, glass capilary tube and oil or water (as both of them "wet" the glass), or melted brass and solid steel. If the liquid doesn't wet the solid - like, say, glass and mercury or steel and mercury - the opposite effect will be observed (mercury can't go on its own into small glass tubes).
And that force that bonds two different materials (like base metal and solder fillet) is ADHESION. And that adhesion, combined with low sufrace tension of the liquid brass (the flux is also helping to lower it a bit), creates that capilary action.
BTW, the force that holds together homogenous material (like, brass or steel, within itself) is COHESION.
brazing is easy if you got the technique down. although i struggle with it i still lay down pretty good welds for a beginner at brazing. love the video you should do brazing on t-joint.
Bronze resembles the color of brass - nice!
I live in the rust belt so brazing is a very valuable skill to have. Could you guys do some cladding oxy/fuel videos using filler metals with melting temps much higher than the base metal. This comes in handy for valve seats. Stoody makes some nice bare wire for that sort of thing.
Awesome, I have not seen this done in 40 years.
That colour is gorgeous
Awesome video. Just inherited an oxe/acetylene system. This was very helpful.
This video helped me alot I had never done it and had to find out for work and by the 4th pass I had it looking great
I learned ocyact welding on my own in my Dads garage on customers vehicles usually on exhaust systems. I eventually was able to patch a hole on rusty tailpipe with baling wire. On a hole the size of a quarter I would tack a piece of wire on one side then the other then lay one next to that one. The next thing would be to weave the two together. You had to get in and out just like you demonstrated. Rinse and repeat until the hole was plugged. In later years a guy told me if I could do that, I could weld anything. Perhaps. I am 68 and find myself still trying to be the welder my dad was. Your videos might actually get me there. A problem that I have is with my Hobert beta mig setting the voltage and wire speed is not nearly as accurate as your machines.
Great stuff Bob. I think gas brazing was tried years ago before actual gas welding. Time I tried that again - you make it look easy :-)
Informative, technical, and easy on the ears. Yeah man, you're good.
Nice work. THANKS FOR SHARING.
I like learning the terminology of welding e.g...Thanks
What are the advantages of brazing over tig or mig? is the weld more flexible for high stress joints? why would i choose brazing over another type of welding?
There are different advantages for different applications, but probably the widest reason it's considered is because of its lower melting temperature for heat sensitive materials.
Wow thank you for this , my dad was a master at this .. taught me how to do this when I was like 6 years old.. I don't want to get into it but yeah.. if I knew now what he knew then..
thanks for all your efforts making these videos , this one took me back to my grand dad and memories that I cherish ! thank you
Hey Bob, Great video you have here. I realize it is a couple years old, but I just stumbled across it. I am a "amateur" welder. I have a small stick welder and a small MIG welder just for small jobs around the farm/homestead. I wanted to ask you "how strong is the brazing as opposed to say a 70,000 psi welding rod?" I have never tried brazing, but could see it as a very useful tool in certain applications. Thanks, RR
If I can do silver soldering, I should be able to braze? I have a lawn mower deck I need to repair, can I patch holes and braze them? I really like the way you explain things. Calm, collected, very sure of yourself, got my attention early and kept it. Thanks for showing & sharing
