Fatigue Analysis of Stainless Steel Overlap Joining Panel Partially Penetrated by Laser Welding

Abstract:

Article Preview

Experiment, finite element method, and theoretical analysis were performed to understand the fatigue phenomena of stainless steel overlap joining panels of different thickness partially penetrated by Nd:YAG Laser welding. The fatigue life curves are obtained through fatigue tests with various levels of applied load. The fatigue life is related with parameters such as thickness of plates, bead width, gap size, and penetration depth through experiment. To understand the fatigue test results, the effects of local stresses around a weld bead are calculated by FEM and theoretical stress analysis as a guide to the laser welding process control.
