Heiple, C R; Burgardt, P

Small additions of sulfur or oxygen to the GTA weld pool in steels with low weld d/w (depth/width) ratios substantially increases the weld d/w ratio and furthermore the improved weld d/w ratio is largely independent of reasonable variations in base metal sulfur and oxygen content. The addition of small concentrations of SO/sub 2/ to the normal argon shielding gas is a simple and effective way to add sulfur to the weld pool and increase weld d/w ratio. Autogenous bead-on-plate welds under otherwise identical welding conditions were made on stainless steel plate with SO/sub 2/ concentrations in the torch gas ranging between 0 and 2000 ppM.
