This web site claims that you can "weld" aluminum with their Super Alloy 5 rods and a propane torch. And the strength of the joint is "weld strength"---30,000 psi.

I'm skeptical. Until proven otherwise I would not want to use this on a critical aircraft part. Or maybe do some destructive testing before committing to your welded aluminum engine mount, perhaps?

[Edit] Just noticed that for "thick" aluminum they recommend a oxyacetylene torch. But what do they mean by "thick"?
