Summary: This paper discusses weld procedure development and unique concerns when welding 316L stainless steel with dissimilar sulfur contents and 100% He shielding gas. Welding procedures were optimized to reduce the effect of dissimilar sulfur concentrations between the lid and can. Discussion of multiple approaches taken to eliminate porosity in the closure region of the weld along with welding procedures used to minimize bead shift during welding will be presented. This paper is of interest to fabricators producing welds on stainless steel with different sulfur levels and fabricators making closure welds in cans.
