Analysis on Finite Element Simulation of Laser Butt Welding for Stainless Steel Sheet
Based on the thermal-structure coupling function of ANSYS software, finite element analysis of laser butt welding for AISI202 stainless steel sheet was studied. In order to realize the dynamic simulation of temperature filed, gauss heat source model was adopted, and APDL language was used to compile program to apply moving heat source load. Finally, with the simulation of welding residual stress filed, distribution rules of residual stress were studied. The comparison analysis among the measured data and the numerical simulation value shows that they have good consistency.
