AISI 321, Ti Stabilized austenitic stainless steel joints obtained by pulsed current gas tungsten arc welding process (PCGTAW) using ER347, ERNiCrMo-3 and ERNiCrMo-4 is addressed. The formation of delta ferrite was observed in the fusion zone of ER347 welds. A slight micro-segregation enriched with Mo content was observed in the fusion zone of ERNiCrMo-4 weldments. Tensile studies demonstrated that the failures occurred in the weld zone for ER347 and ERNiCrMo-3 and in base metal for ERNiCrMo-4 weldments. The formation of deleterious Laves phase in the fusion zone lowered the notch impact toughness and weld tensile properties for ERNiCrMo-3 weldments. The structure-property relationship of AISI 321 welds are addressed in detail and suitable recommendation on the choice of filler material is made based on the research findings.
