Abstract

In present study stainless steel 316L grade was 
chosen for joining using 400w Nd-YAG laser beam 
welding process. 2D transient thermal-structural 
numerical simulation model was developed to simulate 
the complete laser welding process. The effect of each 
parameter has been studied numerically. The optimized 
values of process parameters are utilized to get the 
thermal profiles and heat affected zone using finite 
element simulations. The finite element calculation of 
process was carried out by a parametric design language 
APDL available in the ANSYS finite element code. The 
temperature values obtained using finite element 
simulation match reasonably well with an error of 12% 
hence the developed simulated model can be used to 
study related parameters.
