Default Welding distortion

The doors are having a folded and welded edge for strength, but
because there were a lot of switches and lights etc. there before they
left a lot of holes which needed to be filled. I made some disks of
the correct sizes and thickness and MIG welded them in the holes. This
was in the first door. Smashing, all I needed was to grind down the
welds smooth, a bit of filler and paint. Oh no! The panel has now got
two stable states, both wrong. The panel is distorted and I am
dismayed. Is there any way I can relieve this and make it flat again?

Does anyone have a solution? I would be very happy to try anything.


The welds shrank as they cooled. Try peening them to stretch them back
out. The work'll go faster hot, but doing it cold is safer and less
prone to surprises. A good heavy dolly to back up your hammering is a
must.

Are the two stable states warped with the corners out of plane?
