Fatigue Life Evaluation of Joint Designs for Friction Welding of Mild Steel and Austenite Stainless Steel

The purpose of this work was to assess three joints, namely vee-joint, square joint and plain joint, used for joining of dissimilar mild steel and austenite stainless steel materials by continuous drive friction welding. Three joints were evaluated for their strength, hardness, fatigue life, heat affected zone and metal flow across the weld joints. This article dealt with complete failure data (all samples were tested until they failed). The vee-joint found to be the superior alternative for the dissimilar materials in continuous drive friction welding.
