Purchasing switched vendors and the new vendor thought that they were doing us a fovor by providing tube mill formulation 304L SS (has a higher sulfur content). We are having a lot of difficulty welding this material with nice straight edges one edge is very jagged. How do I fix this problem any suggestions would be great. We are welding @ 45ipm, 80 amps ramp up, 215 amps middle of seam, and 130A ramp down. We are using Ar as shield gas from back top and sides. This provies a very clean weld that does not even reequire polishing normaly if the edges are straight..
