Re: Preventing warpage from welding?

I space the tacks as far apart as possible when I first join the patch and panel, then split the distance between the first tacks with the next group and so on and so on until the seam is complete... In addition to that technique, the old timer at the body shop I used to work at used to immediately blow compressed air over the tacks as he placed them to cool the metal, and I NEVER saw him worp a panel... These two things have worked pretty good for me... I also use a weld seeting of .023 wire, 16Volts and 220-240 in/min wire feed speed if yoru using a MIG welder.... Good Luck!!!
