I notice from the sites that this is technically a brazing technique, not
welding, in that you do not actually melt the base metal. This must be how
they get around the problem of weakening the joint by overheating the metal.
Just be VERY sure to get the joint clean because Al oxidizes VERY quickly
and oxides included in the joint will severly weaken it.
