FINITE ELEMENT MODEL FOR THE EFFECT OF HEAT INPUT & SPEED ON RESIDUAL STRESS DURING WELDINGS

This report is a presentation of ANSYS FE models for the thermal and mechanical welding simulation. To develop suitable welding models, we must consider the process parameter (welding speed, Heat flux, Gap and Temperature), the geometrical constraints, the material nonlinearities and all physical phenomena involved in welding. Therefore it is a great challenge to consider all factors at the same time, so generally the models include some approximations: in the works, we can find some attempts to reduce modelling efforts, and Reduces Residual stress in welding
