I took a 3 day metal shaping class. Part of the curriculum was oxy-fuel (iirc, hydrogen) aluminum welding. You had to get the material scrupulously clean. You had to use a very tiny torch tip (think jewelry) and you had to dip the rod into the flux each time you took the rod out of the flame. I suppose with some significant time trying, I could get the hang of it.... but I'm a pretty good hand with TIG already, so why? It's said that TIG welds are harder than gas welds, but if I have gas welding capability, I can anneal my TIG welds.
