I’ve watched a lot of oxy welding videos and that was the best welding technique video I have seen so far.
Nice oxy fusion welding .i still use my N Z Industrial Gases Prince torch bought in 1968 Same as when I started in 1959
Good teaching ,! Thanks
Thanks! My grandfather passed away and left me all his torch and tanks, so I'm trying to learn how its done.
It's great to hear you're trying to keep your grandfather's legacy alive Kevin Drury - keep at it!
This is great Mr. Natoli! I just started, well going to start gas welding, and your video completely changed my paradigm due in part to my discovery of the Gas Economiser! I've watched dozens of oxy-ace videos and this is the only one that displays it. Also, as a medical student type, i must say your skill is on par with the best heart surgeons. If I were a Tin Man, you could operate on me anytime! Thank you.
Fascinating ! Thanks for the instruction!
Great vid. Haven't welded in a decade. Your channel is helping me to get started again. Thanks!
Great to hear alvaro perez. Cheers
Great video !
Simple straight forward instructions, no bs . Great video
love watching a skilled craftsman- great vid-
Cheers carlo d'angelo - check out the other videos on the channel if you get a chance
GREAT JOB!THANKS I WANT TO LEARN THIS INSTEAD OF MIG WELDING!
Mike Folchetti Start off with stick welding, trust me you'll start off ahead of the learning curve. Watch AVEs vid on it.
Thank you for your fast reply and your videos, extremely helpful for this tin horn!
Of late my welding has become more of a way to waste steel and gas. Not good when I can't afford to have 2 of my cars welded professionally. I'm still not ready to risk my motahs, but just this one lesson has improved things several hundred percent. I look forward to more of the same and have subscribed.
Terrific lesson, thank you.
Awesome video, I learned a lot about oxy/fuel welding sheet metal, like the tack spacing and 15 count between tacks. I think it's too bad that has welding is going by the wayside, there is so much to learn about the fundamentals of welding starting with gas before moving on to other processes. Thanks for sharing your skill with us.
You, sir, are an artist. Great video. Watch those fingers.
Looking the goods Mark, makes me keen to give welding a go!
excellent job.
Great video! Thanks!
Thanks for watching Jay Williams
Fusion welding is underrated and practical is many circumstances when someone is about to scrap a piece saying it cannot be welded since it will not hold up. It keeps the material uniform and if after weld can get the material normalized, you may have given it new life.
good tip, we covered that in welding basics at college
Great stuff. I've done this before, and I just learned a few important things. I'm only on minute 8 so far.
great work!!!!!
I keep getting brittle and crumbly welds on mild steel. Is my acetylene over oxidized? I don't know what's wrong.
The economizer gas switch is fantastic. Where can I get one?
CIG made them ...I believe they are still available...not cheap but saves lots in Gas over time!
You can find them from various makers on Ebay etc. Smith still make them (Smith Gasaver WDW100) new and Smith equipment is outstanding. I collect and rebuild gas apparatus and it's hard to go wrong with US-made equipment since the designs were refined at the peak of OA welding in the 1930s and 40s.
The Oxweld V-31 is a good gas valve. For oxy-acetylene you want part # 16X22. Part # 22X18 is identical except for the pilot assembly, which is designed to use fuel gases other than acetylene. The fuel gas valve is intended for torch brazing with fuel gas. If you find a 22x18, the pilot assembly can be changed out or modified to run acetylene. Alternatively, you can simply plug it and use one of the little electric automatic lighters or even the ol' trusty spark lighter.
I'm having a hard time doing this with 22 gauge, a bit thinner than the 1 mm (19 gauge?) metal in this video. Is it much harder to do this with 22 gauge?
Hi I wear glasses too, so I will like to know the name of your helmet and where to get it. Thanks in advance.
I have 1.6mm steel that need to be welded @ 90° and interlocks every couple inches = to the the thickness of the material so it is thick like a butt weld where it contacts.
How do I deal with the expanding and contracting?
Could we just use a piece of square stock to hold everything together and straight?
Do you feel Oxy fusion welding works better for 2 stroke exhaust pipe welding (rolled cones? thanks
definately ...be careful welding pipes and tanks with fuel vapour around!
It is good to burn the carbon off where mig would not like it so much!
Good Show thar matey.
I can spot rusty beer rings on a welding table a hemisphere away ;) Cheers. Nice clean, well thought out looking shop, and I enjoy your demeanor and teaching style. It's easy to distinguish a man that knows his skills (and probably developed them himself with little formal training) and has a mind for this sort of work from a UA-cam professor or a hobbyist talking basic things or even misinformation as if a professional. I'm sure you're aware of them.
I don't have much experience with gas welding. Perhaps you can offer me some arguments to learn it? I was really surprised to see how straight that example stayed after all that heat. I mean that whole sheet looks pretty cooked to a TIG guy, but not nearly as warped as I would have expected. I'm assuming that has something to do with the more even application... and perhaps if I continue this conversation with myself I'll find the answer to my next question... Surely there are some advantages over TIG in certain applications? Aside from when they shut off the utilities? ;) Would you be able to achieve the same results in hand formed panels with a TIG? Is warpage mostly accepted during welding and then beat out later in your field? I must know! Thanks, and best of luck to you and your endeavors from New York. Precision sheet metal fabricator/designer type person here. Mostly CNC. Auto/Aviation/etc nutcase.
Hey tigweldNY - few good questions there...
Oxy acetylene is the softest of the welding processes and I am used to it's capabilities to be shaped after welding. TIG however is the next (and you may know more than me) still shape-able after welding, with no excess metal. The key is to not over heat and watch the metal as you work it - patience is very important in the oxy welding process. Yes I think that with less heat you would be able to achieve the same results in hand formed panels with a TIG welder - especially with your skills. Warping can be shrunk using heat shrinks and the oxy torch in old panels (not so much the new high tensile modern steels). The 'beer rings' are actually just acid from a flux - don't want to waste any good beer!
Thanks for watching and the good feedback. Cheers
good job on this video...
Is that a flat-faced hammer that you are using to dress the weld?
When burning rod you're adding a filler metal to strengthen whatever you are welding up. The benefit is strong welds that can be used on anything from back yard repairs to x-ray quality pipe welding, fusion welding is for non structural stuff.
Douglas its done to hide welding seems, like for autobody. Its for Looks. Also used for non structural weight supporting Welds. Ie fenders, metal art, jewelery, many other uses.
What is the benefit on this fusion welding versa burning a rod down it ?? Thank you for sharing.
Welding small stuff:
I have a metal lens adapter ring super-glued to my camcorder to attach wide angle lens or filter or lens hood. It has been knocked off a few times and super glued back on.
I want to weld it to my camera instead so it stays forever. The front part of the camera is metal too by the way.
extremely high heat will not be good for the camera, nor would the high current of arc welding. Use a 2 part epoxy or something other than super glue, super glue is actually a pretty weak bond it just dries fast. Clean both surfaces of existing glue and stick it on there, just don't get anything on the lens
i love the torch
Do you have any specs for how much gas those small torches use? I have an old AGA X11 torch I got from my dad, there are low pressure mixers and tips for both propane and acetylene, I think the smallest tip uses 40l per hour. Dunno what units you use for measuring,
+1873Winchester Also are those gas saving thingies safe to use? Seems like they don't follow proper shut down and start up procedures doing that? I'm new to this so I am a bit jumpy about OA.
try putting a tack on each end of the metal first then it wont pull apart just a suggestion
mantap... tanks...
What brand of torch is that you use and recommend? What size tip. thank you
It is a CIG Colt torch with no6 tip for 1mm sheetmetal
what diameter tip are you using???
This type of welding is still more practical than forge welding though. No one forge welds anymore, afaik.
I think Ren Fair blacksmiths forge weld when making swords, and possibly ferriers do occasionally, but other than that, probably not.
You know where I am mate!
Enjoyed your video but you neglected to explain the first thought many have and that is tacking both ends rather than manipulating the gap by going from one end to the other
What is the switch/pilot light device called in the background?
Just Google "gas saver."
I have one made by Murex in the UK. It's called an economiser.
Why do you adjust your tip to neutral without your mask? just wondering, because I was taught otherwise. as well as, when in the real world is oxy-fuel welding applicable?
Oxy-acetylene welding nowadays is used mainly for maintenance jobs and hobbyist metalworking.
Hey Essentia Gaming - good call, I am used to adjusting it the old school way. But your gear and workplace safety is very important.
In terms of when oxy welding is applicable - mainly in vehicle restoration on vintage cars and bikes - both aluminium and steel. Coach builders still use oxy. It really depends on the project and what welding process is most appropriate for the job.
thank you....
What's that C or K word he keeps saying? "Distance of the caern(?) is what you want"
"Cone", there is a tiny blue cone formed by the gases as they come out of the nozzle.
I wonder if this guy has heard of the Cobra torch, which provides the closest welds to TIG that oxy-fuel can deliver. It's even more practical than the regular torch and saves a lot of gases. I love how Cobra outweighs the disadvantages of the 111 year-old oxy-acetylene torch.
He mentioned it in the video-the Henrob 2000 (same thing).
Yes Seph Angelo I prefer the small 111 year old torch as its more comfortable than holding the gun style... Both of which are closest to TIG in case you didn't know, low pressure save heaps of gas especially when you have the cut out switch. Cheers.
All that is subjective and mostly a matter of ergonomics. That's why many users have a variety of OA torches from jewelry size to heavy scrap cutting. It's fine for you to prefer the Henrob/Cobra design but less so to talk silly shit about the others. Henrob/Cobras are heavy (though you can skeletonize them by removing the body castings) and the pistol grip isn't idea for every job or user. I've used Henrob/Cobra, Smith, Victor, Oxweld/Purox/Linde and their relatives, Airco/Concoa, Meco and others (I collect and rebuild OA apparatus). I own all the above mentioned brands in multiple models except then Henrob design which I don't want after trying it out.
The operator produces quality welds. The torch isn't critical provided one uses a clean, undamaged tip of the right size at the right pressure settings.
Everyone's heard of Dillon/Henrob/Cobra and relatives. They've been out for many years yet have not replaced other OA torches in industry and remain a hobbyist piece. They are nicely made yet pistol-grip torches from other brands are rare. They are nice for out of position welding but their bulk and lack of reach compared to conventional torches is a factor for many users.
It's cheap to collect quality torches so try a variety. Most gas welders have multiple torches. Torches don't get jealous of each other.
Ob Fuscated ...I’m pretty sure the original Dillon/Henrob was invented in Australia. I agree, it’s a bit on the heavy side, and the ergonomics are average. I picked up a really small torch from the States that’s used a lot in classic auto restoration, really good for filling pitted surfaces in spoked wheel rims etc, and also good for OA welding of aluminium, the name escapes me at the moment but I’m sure you’ll know the one
I thought it was bad for your eyes to look at the flame? 3:02
Maybe if you did all day, but oxy-fuel torches aren't that bright.
This is ripper stuff, mate! I've been scared to death of MIG ever since I had a joint fracture on me! (Probably my shitty welding!) Next challenge is to do a vertical run!
Dude, you’re fuckin’ awesome!
With this type of welding that would cause massive warpage.
Thanks, gas welding isn't taught at our school unless you can prove a future employer requires the knowledge, odd. We use gas for cutting and soldering only...
This doesn't seem that efficient. Why not clamp both ends squarely in place... then just run the 2 plates under a spot welder? I'm not a welder but that's what I'd do. It should be much faster and provide the same results..... no?
That a way to do it ! But i think you're missing the point here ,the point is to learn oxy-acetylene fusion welding and not to show the best way of going about the job !
Rob, the object of the exercise is not to join two rectangular pieces of panel steel, it's to show us how to gas weld panel steel, the best method of joining panels.
it's fusion welding
Never need a MIG.
Anyone from Ford motors😁
22 minutes to weld 8inches.
It's called doing q good job
+GAMEMASTER2429 I guess.. but I weld sheet metal for my job and it took me that long I wouldn't have a job
613repforme true i guess there has to be a mix of quality and speed but i think its also taking him a while because hes talking and explaining you know
