Continuous Drive Friction Welding Studies on AISI 304 Austenitic Stainless Steel Welds

Abstract

Abstract An attempt has been made to study the friction welding characteristics of an austenitic stainless steel AISI 304 employing a continuous drive friction welding machine. The central region in some of the welds exhibited abnormal grain growth. Optimization studies revealed that the optimum parameters depend on the property of interest. In general, friction welds exhibited lower notch tensile strength and impact toughness than the parent metal due to aligned microstructure features. An inverse relationship has been observed between notch tensile strength and impact toughness.
