I am narrowing a Chevy 12 bolt for a HotRod I am building. I cut the tube 2" from the flange and offset half of the cut 1/4" for extra safety. Both ends of the seam have beeen beveled and the end were tacked welded back on using a straight rod going through the complete rear end. My question is using a Lincoln SP-135 set at G/3 and using .035 flux cored wire. How do I finish welding without warping the tubes and changing the alignment? |
