Fixing undercutting on a weld
Posted: Wed Oct 02, 2013 9:54 pm
When I built my leafer I had undercutting on the lower leg welds where the tube meets the .5" bar. I haven't ridden it yet bc I haven't found a hub narrow enough to fit that allows for disc brakes, and bc these welds bugged me. I cleaned them up today and made narrow passes above and below the weld where the undercutting was and finished with a cap. My question is, does doing this on the tubing cause it to become brittle and unsafe? I have used this same technique (multiple passes with a cap) on thick stock with no issue but not sure about tubing.
