How can I weld aluminum with oxy-acerylene?

[AntoineJackson]

Although Oxy-acetylene is not recommended for Aluminum welding, but still I want to weld aluminum with oxy-acerylene how to go for it?

You need Hydrogen. Gab a torch and some filler and go for it with oxy/acet and send us some pics. We will be dying to see the results...Bob

Check this thread. I have not seen the old Alcoa video mentioned but I suspect it would be good

The Linde Oxy-Acetylene Handbook has a good chapter on gas welding aluminum-available at Amazon. Also, the following link is apparently some military version of that book and is available free on line.

Still common on aluminum bodies and aircraft...
(I still have my BurtWeld goggles)
several old threads here if you search

I have a good friend. He is the mechanic, second in command for a family excavating business. He's brilliant, sort of a real life McGyver, the kind of guy you want around in an emergency. Oh, and he's assistant fire chief, his father, by the same name is chief.

After a family/corporate vacation in Las Vegas he proudly showed me a new product he'd found. In showman style, he punched a hole in the bottom of a Coke can. He scrubbed it with sandpaper, and picked up an oxy acetylene torch. Working slowly around the hole, he built up filler until he closed the hole.

This was before I owned a TIG welder, I was impressed. Later I bought some of his product. I couldn't find practical application for it.

I've heard there are people able to weld AL with acetylene. I can not.

I have some of that stuff. The pitchman does a really nice job of filling a hole on a coke can, but that seemed to be the end of the line for that stuff. I've used it on a few small jobs, but that was before I had AC HF tig. I think they sell it as a high tensile strength, low temperature brazing rod. Looks like soldering to me.

It really is because it doesn't melt the base metal. That's why they "butter" the edges on some parts first so the solder will stick to itself. Aladdin 3 in 1 makes a good product...Bob

THAT is soldering

BUT oxy/fuel aluminum welding is a real learned skill....

and yes you do fuse the base metal

Do you know if the other products that company makes also work as advertised?

Looks like they would be useful for ornamental projects, when epoxy or TIG is not suitable. Especially the ability to join dissimilar metals.

Thank you.

Oxy-Fuel Aluminum Welding has advantages over TIG in some applications like car bodies and aircraft fairings .....
