Which brings me to another point, since you've mentioned SS wire... I learned from a guy who worked at the power plant and has to have all his welds X-rayed, if you run into porosity problems for what ever reason, and you pop a pore, everyone knows if you go over it with mild wire, the pore will just reappear. Go over that section with 309 SS filler, works like a charm! But you didn't learn that here, I'll deny everything! It only works if you just have 1 little bad spot and the proper thing to do is grind it out and re-weld it.
I have never welded anything as bad as this pipe. I cleaned the outside, but did not notice that the inside was also painted. It came to me tacked together. The weld just bubbles as the air escapes. I thought I could welded it with stainless filler, although the bubbles were not as bad, they still appeared as the weld cooled. Do you think it was the type of pipe or just that the pipe was painted on the inside?
I told the person that brought it to me, to cut the tacks apart and glass bead the inside of the pipe and I would try again. But this company feels that the paint has nonthing to do with the problem. Since then I learned that 3 other welders refuse to even try to weld the pipe. |
