Preventing warpage from welding?
Im currently installing my floor in my 71. I noticed that when i weld over 4 inches at a time, the floor tends to warp a bit.. Im not to worried about that because it will be covered in dynamat anyways, but i am concerned about when i do my patch panels.
What are ways to avoid warpage? Bucket of cold water with a rag? Tack weld the whole piece?? Any and all tips are appreciated... |

On flat areas anyway. Curved and bent areas are more tolerant to running small beads. |

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!!!

Re: Preventing warpage from welding?
 4" bead is just like asking "hello mr. panel will you please warp"... do like fizzle fry says and tack the whole thing in....that is the best, less destortion way to do it..

Re: Preventing warpage from welding?
I learned the hard way and had to redo a panel. but yeah, tack tack tack, let it cool down some in between. It takes a lot longer but comes out 100x better.
