I have seen a bit of discussion about spot vs MIG welded panels. I am
no expert on weldong but, spot welds can be done with a MIG. To do this
drill a small hole (~1/8" or so) in the front panel where it touches
the rear panel.

Next weld the rear panel to the front panel inside the hole and fill the hole

grind the weld flat and you have what looks and acts like a spot weld.
Any MIG experts out there that can describe this better than I did?
Also a trick to filling holes in sheet metal is to place a piece of copper
behind the hole as you fill it in. The steel won't stick to the copper
so you have something temporary as a backing. Just be sure to do a small amount
at a time so you don't heat the panel and warp it!
