By the way -- I don't think you could NOT have warpage on that flat plate of some kind. Any time you heat metal you expand it and when it cools it shrinks... since you're welding in only one area that area is going to expand and contract more (warpage).
What you may need to do is to make your gauges match --- but we don't know what you're building...
Does the piece require the two gauges of metal? Could you use an L shape and just plug weld it? Or use a thicker gauge and drill and tap it to attach your flat?

It is a radiator support. The "flange" is basically a close out to clean up the transition to the radiator core and giving a recessed area where the A/C condenser will sit. The flange is not structural- mostly cosmetic but having the added benefit of stiffening the panel. I know it can be done... I've done it on smaller pieces without the warpage- I've just never tried a large flat panel like this before. I'd rather not use angle iron as this is a high end build and I'm trying to make it as nice as possible. I just need to figure out what I'm doing wrong with my technique. I guess I could build a separate sheet metal "L" flange that I could spot weld instead of having to weld the entire edge...
