Lots of good advice here.

Crash0637, that is sunken from welding. If it was butt welded, you should be able to work it back out by stretching the heat affected zone (HAZ). If you cut the angles wrong, you will have to cut it back off to re-align it. Also, grind the bead off the back side before hammering.

ALL welds shrink. It doesn't matter if you cool it or hammer while hot. They ALL shrink. The secret is keeping the HAZ as small as possible. ALL welds shrink = ALL welds have to be stretched.

Learning to work a weld takes a lot of practice and experience.

There are only 5 rules of metal shaping. You can CUT, WELD, SHRINK, STRETCH, or BEND metal.

Also, never lap weld on a visible surface panel.
