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.
