When I did my apprenticeship as a mechanic, I had to oxy acetylene weld aluminium in order to pass welding. I've only done it a few times since. One of the more difficult parts of this process is knowing when you are getting close to welding temperature. You can use a match stick as a temperature crayon. You drag the back end of the match across the material. It will leave a black line when you are close to temperature. You can also use a bar of soap. Same thing happens. Have had many arguments with 'welders' on mine sites about gas welding aluminium. Just about everyone that I have met thinks it's impossible. Would like to see you do the same video with oxy acetylene. Regards Greg
One thing I’d like to point out for the new welders is that he says that gas welding is extremely picky. What I’d lick to add to that is that welding on aluminum in general is picky. The best way to fight this is to always brush in one direction when preparing the metal and clean it from other contamination along the way. Patina that covers the aluminum has a higher melting point than the aluminum underneath.
Good tips, I've only TIG welded Alum. and was also told oxides will start to form within 2 minutes of cleaning it. So don't clean it then go take a lunch break lol.

Question: If I have a TIG to tack with, why not finish the weld with TIG? If I don't have TIG, only a gas torch, what is your recommended technique for tack welding?
This is how the famous “REACTOR” car body was lovingly fabricated in the 1960’s. , it was featured on Bewitched & StarTrek and many other tv shows of the time 👍🏻
Good video, informative. Is it possible to torch weld aluminum without needing to sell a kidney? My doctor tells me I need the one I have left after selling the first to buy the oxyacetylene setup. Thanks
I used to wash my hands in bowls of acetone several times a day when I worked at a fiberglass shop. I'm paying for it though, it's definitely caused some serious health issues
With my time as a Airframe mechanic. We never weld on aircraft. Mind for a few items that parts are not available, TiG , and NDT. Usually Titanium , stainless steel alloys, Inconel, maybe a few others. In the older days they built the Airframe from 4130 all gas welded. They wrapped with thin fabric and used a resin.
Yep. Haven’t welded on my aircraft since… last year. Seriously, lots of 4130 airframes out there, and nearly all engine mounts. And tig doesn’t normalize much cross-section. (Still a lot of welded aluminum fuel tanks out there too. Usually bent to weld a doubled edge, rather than butt weld or fillet. Much simpler with a torch to do a doubled edge.)
Panel fabrication and repair. Both the weld and the surrounding parent metal are annealed, making further shaping and finishing easier, along with reduced chance of splitting.
Watching this video on how to gas weld aluminum is like watching a how-to video on making a hamburger: first, buy yourself a farm and a cow, next, get a juicy steak to make sure you’re well fed, we’re almost done, now just proceed to make a hamburger patty and cook it. Thanks a bunch.
Welding aluminum is relatively easy using oxy/acet if you have access to flux containing flouride as a major component. Lately I notice it's not available, and if you have a siurce olz let me know. thx
Interesting. Most Al stuff I do is high volume spoolgun. Truck frames and floors are thick amd dirty so the 100% cleaning action of spoolgun saves a lot of time.
Over 3mm th. use mig. Push/ pull wire feed or real on gun. Down side of OA is use of corrosive flux. So it's only for butt & outside corner joints. Fillet. Lap. are flux traps.
I would like to see how soft the aluminum is after doing this. Can you weld a boat hull or would it not stand up to the beating after. Is this a project you are willing to take on to show durability of the weld method?
@Alaska Life If you watch the extended version of this video in the WELD app, you will see Matt put the weld through a stress test and show you how strong the weld really is.
@@GRich120 the welds are like flexible. I welded together a angle piece out of two aluminum flat bars and while the weld looked pretty bad I could bend it back and forth with a hammer. Inverted angle piece...
Wow! All BS aside I enjoyed this video as much as any welding video I've seen, your delivery and weld shot were excellent, I have been welding for many years but there are always new processes to learn from. What is the main reason you choose to weld with gas vs tig. I have not ever heard that question answered. I built a Gas tank for my motorcycle with 3003 only time I ever used it, no body filler was needed when it was finished, only about 40 hrs of work.😂
haha man I have O/A for a while. I like brazing and even steel welding but aluminum welding on it was so hard. I started to think I was some how challenged but I finally got a tig and it is EASY in comparison. I don't know much about it but lets say making something that looks right is like... 10 x easier on a tig. A DHC2000 torch helped but still you really gotta practice doing it. Get the flux from that british company and make a flux tray and its better. It feels good to do and know though. And as always being able to work without electricity is wonderful. You know in case you need to fix that B52 that lands on the high way in the middle of a nuclear war when the lights are out.
I'd like to see a twin carbon arc torch being used for aluminum welding. Of course flux is allowed. I did however see rocks get molten by a single carbon arc at DCEN.
btw if you anodize it after gas welding your gonna make the skin tough and I read what that does is make parts that suffer internal cracks. If you need it flexible after gas welding I believe the proper coating is alodine and paint. I read thats why they don't annodize certain plane parts. Sudden failure after many stress cycles due to the anodization and paths of stress.
Yeah, sure, just hang out with a burning torch. No biggie. WHAT COULD GO WRONG??? (I say as I look at the Nike swoosh scar on my forearm caused by hanging out with a lit torch.)
The regular green goggles wont filter the sodium glare. You need either cobalt blue or purple didymium lenses to block yhat or uou cant see what your doing. Those lenses however eont block the ir. The lense manufacturer of the didymoum lenses specifically says they are not sufficient for welding. I caljed them and they explai ed tvst you have to back it up with the green ones. Then your good. You can use tge round cobalt or didymium ones in the green welding goggles eith the round lenses (the crazy inventor goggles) or you can use the square ones in the appropriate goggles. Just put both the green and blue or green and purple in. I use a a pair of Bolle Tracker goggles in #5 green with a "prescription" insert, but i just had them put plain didymium purple lenses in the insert with no prescription.
Funny you say that. The designer of the Blue Feather torch modeled it after the Cobra torch and made some improvements on the old design. Nice eye, man!
good torch but its heavy if you are welding standing with no arm rests up you need to be going to the gym to really maintain a bead for a long time, I had problems. Its like that scene from terminator 2 where he is holding the radio on top of the barrel.
you can tack it with gas but its some what harder. Like what you would probobly do if you only had gas is first tack it, then clean it up with like a acid, then weld it over. Its easy to get like soot contamination and stuff on it everything while your tackin with o/a. And the other problem is you get it mad hot so its like after you tack the first one you need to realign it probobly and then tack the second one and maybe work on it a little bit. Tig does it clean and easy.. O/A aluminum is weird because you see it really haul ass due to thermal expansion.... that torch puts ALOT of heat into it.
I had a leased tank because I thought I could weld Al with it but I liked O/A better so i gave it back. The flame is fucking LONG from a O/H torch. Like with O/A I got something that looked kinda like butter but with the hydrogen it looked like warts. They say its better but something was off for me.. maybe if your advanced skill level. But I mean a hydrogen tank not the stochiometric electrolysis mixture. You need a tank for O/H welding properly AFIAK. Its like a light saber lol, I burned stuff at a distance that was fine with O/A (ear protection on the shelf)
when I talked to the weld store central around here they said its like old timers that do it for fun. A few people know how to really do it good but they mostly sell big H2 tanks for gas mixers in volume welding... alot of companies have custom gas mixes with H2, or require a few diff mixes , so its easier to buy a H2 tank and manifold/mix it with other stuff (its usually a low % concentration).
You've got the Tig setup, why not just Tig weld it? Spending all that extra money for gas, regulators, flashback arrestors, hoses, welding torches, and eye protection - seems pointless ! 🤔
We have found a gas welded seam holds up far better then a tig seam for a fuel tank because it’s flexible and strong it can hold up to the massive explosions that happen in top fuel drag racing and also just normal abuse seen in racing in general
I think you get a better grain profile within the metal and potentially a better weld there are also niche applications where TIG welding might not be an option. TIG welders give off a lot of EM and other radiation that can interfere with or harm sensitive electronics. Besides this is just educational content demonstrating how a certain process works not arguing it's the best process.
no electricity, quiet, cheap. He put the ritz on it but you don't need the expensive stuff. And for doing aluminum its still 10000x less PITA then dealing with Al braze.
Neat video but I am confused why anyone would ever do this. Why spend a few thousand dollars on new torches, new glasses and special lenses just to warp, I mean weld aluminum when you already have an AC/DC Tig welder? It just does not make sense to me.
he is showing the best way you could do it with a cheap torch and normal glasses (even plasma cutter blue goggles). He put the ritz on it. DHC cobra torch is nice and cheaper but you really don't need much if you have the technique. And its sick because its a really soft part and its quiet. Not everything needs stiff parts.
@@k.c.maclachlan3227 you never saw aluminium radiators back then. They were copper or brass. Cylinder heads and panel repair, rocker covers, manifolds etc
@@theshed8802 I'm a fitter we did brazing as part of apprenticeship but even plumbers dont use gas brazing anymore. I use brazing now to repair throttle cables etc
But why not show a close up of a finished work piece?? Because the green light wasn't showing what we wanted to see The video was okay ...but the last part flopped I mean you've got to show a finished work piece to convince people that they can actually try this out..

So many different ways to weld aluminium. Neat stuff really enjoyed that.
Not sure that I'll ever gas weld aluminum....but I've always wondered about it, & a lot of great information in this video. Thanks!
One thing I’d like to point out for the new welders is that he says that gas welding is extremely picky. What I’d lick to add to that is that welding on aluminum in general is picky. The best way to fight this is to always brush in one direction when preparing the metal and clean it from other contamination along the way. Patina that covers the aluminum has a higher melting point than the aluminum underneath.
Good tips, I've only TIG welded Alum. and was also told oxides will start to form within 2 minutes of cleaning it.

🤔 could you weld thin gauge aluminum with a small butane torch & aluminum mig welding wire dipped in the correct flux ?
FYI in all the UK welding textbooks Oxy/acetylene recommended to use a carburizing flame for welding aluminium.
well you people drive on the wrong side, so what do you know

If I'm tacking with TIG, I'm welding with TIG. Sorry. ... But the hydrogen torch is interesting.
Yeah I thought this technique is primarily for cast aluminum, as thicker castings have high thermal mass and need no tacking to repair cracks.
*re: tacking, demonstrater appears to be touching tungsten to aluminum much longer than in a lift arc scenario, are they lifting at all?*
tacking with tig can be nice for stuff that is getting mig welded but you dont wanna feather the tacks after
You can tack with a torch. I guess he just can’t
@@zachcrowl8504 tig gives better heat control for tacks this is basic shit

DHC2000 torch does it but its not cheap either and you need strong hands for that thing like upper body gym stuff if you work standing
That looks difficult; thanks for showing. I'm cool with SMAW and recently added MIG.. but yikes!
Been looking forward to this video! Flame weld great for exhausts too
To prevent the blowouts, I like to put about a half inch tack on one end, then work toward that end.

When you don’t have a TIG machine.

T'es un amateur vu comment tu tiens ta torche lorsque tu pointes tu dois mettre du métal d'apport surtout sur l'aluminium et mettre aussi de la contrainte.
Quel intérêt de pointer au TIG et de souder au chalumeau après?
I hold it the exact same way
