Yes Tig welding, 0.040 rod and the gap is 0.02 or less. Spot tacked every 2" adjusting as I go working my way around the perimeter & grinding after every 5 or so tacks. Then I jump around with tacks 1/2" off of those then jump around with 1/2 off the first set the other way. Grind and adjust. I weld the 1" open sections and adjust hammer dolly as I go. Then I come back jump around and weld the 1" thru that first tack doing the same thing. It might take me a to week scrape up enough time to weld that much on this car. It's like 120" on each quarter and half of it is in the open field 2'' away from the beads - might as well call it the middle of a low crown panel. Now it looks like it's been kicked by a really pissed off mule. I'm going to guess here that it's being hammered too much during the process. Instead of the welds pulling the distortion in that its my hammering stretching the edges of the panel. There's metal magician guys who fit the panel tack it and weld it from one end to the other without stopping, then come back and finish it off and you can't even tell they were there. I wish I didn't know that because it's really pissing me off.
