A three-dimensional analytical model was used to predict the temperature distribution and thermal cycles of a 2 mm thick 316L stainless steel during laser welding process. The welding parameters such as input power, welding velocity, various thicknesses and at various time steps are predicted the temperature distribution and thermal cycles of a 2 mm thick 316L stainless steel of moving laser heat source during welding process. The optimized laser welding parameters such as laser input power and welding velocity from the analytical modeling are used to weld the 2 mm thick 316L stainless steel using pulsed Nd: YAG laser source. The experimental observations are correlated with the results obtained from analytical modeling for welding of 2 mm thick 316L stainless steel and found very close association with each other.
