Assessment of Mechanical Properties of AISI 4140 and AISI 316 Dissimilar Weldments

Procedia Engineering, 2014
AbstractBimetallic joints of low alloy steel and stainless steel are widely used in high temperature corrosive environments. In the present investigation, an attempt has been made to investigate the weldability of AISI 4140 and AISI 316 by Gas Tungsten Arc Welding (GTAW) process with and without filler metal. The filler metal employed for joining these
