Hi everyone. I have been doing a lot of practice tig welding with .040 er70-2 filler rod and .035 wall 4130 tubing from Aircraft Spruce. It has been a long steep road but I am finally getting a handle on it. I have been using pulse settings (80A peak, 15 base, 2 pulses per second) with the lay wire technique. My torch is a CK130 with 1/16" 2% lanthenated tungsten. My welds are looking better on the first pass. I can make them look better if I take a second pass adding filler rod in the thin spots. I am still practicing and my goal is to get it on the first pass but I was wondering if it is a bad practice to go over the welds twice?
