[Shop-talk] Welding Sheet Metal

[Bob Spidell]

I need to make a car body panel repair.  I can either MIG or TIG.  This will be 
a butt weld on thin (22-24 gauge) sheet metal.  I've done it before with a MIG; 
it seems the best way is with a small gap to start and a series of tack welds or 
short beads that eventually join up.  With a  TIG, I think I could have less of 
a gap (or no gap at all), could run more of a bead and hopefully deposit less 
metal, but I'm also concerned with burn through.  I'm an amatuear welder, but 
getting better.

Recommendations?

TIA,
Bob
