Have been welding for about 30 years, have joined metal from .010 " to 2"
thick , worked as certified Aircraft welder for several years, mostly TIG or
GTAW and Electron Beam, typical aircraft tubular assembly would be either
..035 or .049 wall thickness, electron beam of Titanium would be on the order
of .25" thick, welding light gauge 4130 or 308 Stainless would require very
little D.C.to join, if one were to join two pieces of .75" ,6061-T6 Alum.,
you would need A.C. with the square wave skewed to nearly 70% negative with
75% Helium 25% Argon gas and approx. 400 amp. at the torch , this load will
pop a 100 amp. breaker in a heartbeat, and no I have never done any ship
building, thanks for your interest. Dr. Phil
