Paper Title:
Study of Type 316L Stainless Steel TIG Welding with MoO3 Powder
  Abstract

In the present work, a specific oxide flux was used to systematically investigate the effects of activated tungsten inert gas (TIG) welding on the surface appearance, weld morphology, angular distortion, residual stress, and ferrite structure in type 316L stainless steel plates. MoO3 flux used was packed in powdered form. The results showed that MoO3 flux assisted TIG welding technique can produce a significant improvement in power density of heat source and weld aspect ratio, resulting in low angular distortion and residual stress levels. The MoO3 flux assisted TIG welding associated with a rapid cooling rate of the welds, therefore exhibiting higher ferrite content in austenitic stainless steel 316L weld metals during the solidification after welding.
