I am just starting to build my 1st real project but have been planing for some time now. I am great with my MIG but I am going to braze my chassis I think. I have a butane fueled soldering torch. I can remove the interchangeable tips and just use the flame that is produce like a small oxy/acet torch.. Would that work to braze the metal?

Or do I have to use another process for alum tubing? Sorry for the dumb one but I'm just used to welding steel on my 1:1 projects and don't have much time welding other metals in other ways then Mig

Thanks

Tigging aluminum is the best. But needs to be high frequency. You can mig aluminum with argon gas. Brazing aluminum is a tough one. I've seen and heard about durafix, but havn't tried it.

I brazed ally for the first time ever this past weekend. I used durafix and a normal (cheap) butane torch. I had one real bad looking weld, then I started pulling it off one weld after another. I have only arc welded and tig welded stainless before. Problem I found was that the torch takes very long time to heat the ally.

Yeah i tried brazing alu with a mapp gas torch and well it melted it was going good until i touched the bumper with the brazing rod. After i kinda figured out the melting point it went good.
