Your local auto body/paint shop will have this or something similar

The repair needs to go out to good clean solid metal. If the replacement pan isn’t big enough you may have to add a transition patch.
I always use that gray putty like seam sealer with an acid brush. Seals and hides sins with one quick step.

Your basic setup sounds good. Are you trying to do a but joint or lap joint? A lap will be a bit easier. Start with spot welds, find a time that won’t burn a hole and do a bunch of spot/stitches and let things cool down. Once you have a cool spot bead you’ll have a little more material to make...

A welding table can never be to big or too strong.
Corollary: my next table will be bigger and stronger…...

So it’s a ‘87, $1K, clean looking. Takes a Spoolmatic 1 that I can’t find any for sale.
Really don’t need two 80’s welders and to spend a bunch of money on an old AL MIG setup.
Still drooling for a 255 with a push pull setup.
