Technical '36 fuel tank question.

Yes or no, can I mig weld this back together after I finish cleaning it out and it still be useable?

I don't see why not.

 

When I cut my 40 Ford tank like you did, I gas welded it back together. I did notice that a tiny crack would appear
in front of the weld bead. So I drilled a hole at the end of the crack and applied a fiberglass mat strip on top of the weld bead. It never leaked. That was 50 years ago. Today I would MIG weld it, 1 tack at a time, spaced out evenly.
