I've seen guys at expos and fairs, etc., use a torch to do what looks like soldering or brazing two pieces of aluminum together with some sort of aluminum-friendly rod,.. making it look as easy as soldering copper with lead solder.
WOW! That must take some kind of amazing skill, or at least some trickery I don't know about. I'm a barely functional welder as it is, but I've always been told that Aluminum can't be welded with a torch because it dissipates heat so quickly that by the time you melt the part you are trying to weld, the whole thing slumps into a puddle.
But yeah, I suppose if you used a cooler temperature torch, you could probably solder it together in some form? Definitely going do some research on that idea. It could make sometimes costly repairs to engine cases a lot more manageable... even if you just find the right guy to do it for you!
