Evaluation of residual stress distribution in laser welding process including the effect of phase transformation kinetics

Abstract

The accurate assessment of welding induced residual stress is pivotal due to its detrimental effect on structural stability and mechanical performance of welded structure that can reduce the fatigue life and premature failure of the welded joints Especially the thin structure is susceptible to severe distortion and locked in residual stress development due to relatively low stiffness and high heat input during the fusion welding process In the current research this takes as a window of opp...
