Buzz little spots with plenty of space between to keep heat down to prevent warping. Planish the welds after completing each pass across the panel while they are still hot. This counters the shrinkage of the panels as they cool. If you ever feel like you're making good time on stitching the panels together, you are likely going 3 times too fast.
