Finite element analysis of residual stress from welding process

Finite element analysis of residual stress from welding process

This study investigates residual stress from welding processes which are butt welding and laser cladding with the use of finite element software, ANSYS parametric design language. Two models were simulated for each welding process. First model does not take into account material addition during the...
