on 3/27/2009 I thought your supposed to weld on clean metal not primed/painted. Why are you welding that way? Does it have an effect on the structural integrity?

Video Transcript

"Hi, I'm Doug I work with 20 great guys in Saint Louis at Doug Jenkins Custom Hot Rods and we are going to do some work for you today on Expert Village. Alex takes the primed piece that he has and he gets it all trimmed in the edge. Gets everything fitting perfectly and then he welds it in place. The tact weld because you want to get it in the right shape, in the right place and you want to be able to make sure that it fits correctly if you weld the whole thing in and try to cut it out that is a hassle. So tact weld is easier to cut out. Then he stitches it together short welds so that the metal does not get to hot. If you weld the whole thing all at once from one end to the other and don't stop you would warp the steel because it would get to hot in one spot and not the other. The differential heating would cause it to warp."
