Paper Title:
Phase Formation in Austenitic Stainless Steel A-TIG Welds
  Abstract

The aim of this research is to study the effect of the welding conditions and of an activating flux on the microstructure of the melted material of autogeneous A-TIG welds, made on austenitic stainless steel AISI 304. The increase of heat-input coarsened the microstructure, changed its morphology and decreased the δ-ferrite content retained in the microstructure. The use of a TiO2 activating flux does not significantly affect the microstructures. A thin layer tends to form in the surface of the welds, which microstructure and ferrite content are different from those observed in its core.
