[Shop-talk] Welding Sheet Metal

[Eric J Russell]

Browse around www.metalmeet.com (click on the link to 'forums' then ~ 2/3 
way down is a section titled processes  > joining metal). Be warned that 
that site can be addicting...

The MIG technique I use is to skip weld short tacks (1/4" long), hammer the 
hot welds to minimize the shrinking, grind off about 9/10's of the weld bead 
then skip weld between the previous welds, hammer, grind & repeat.

If you have access to the back of the panel a copper backer helps to 
minimize burn through.
