For purposes of informal survey, what welding technique were
you using? Did you do the seam in sections or as one pass?

Does it look ok, other than the tension? If it looks fine, leave it.
Let
the tension stay.
Anything you might do to remove the tension might cause you more
work. You could heat the whole piece up and let it cool again, and
it might take the shape it is held in. It also might crumble into
an accordion, leaving you with a lot of filler work.
If this was aviation welding, the stresses in the panel would
be very bad. But for cars, I wouldn't worry.
To stop this kind of problem, weld in really small bits and let
it cool. You can also use the million dollar putty, but I am not
sure it's necessary. I bought some and used it, and it works, but
at $25CDN a pound it might be something I'd do without unless
I was REALLY trying to protect something nearby like glass,
plastic, or paint-that-must-be-saved.
