Abstract

A numerical simulation of temperature distribution of laser welding of 316L austenitic stainless steel has been investigated in the present research. A three-dimensional Gaussian conical moving heat source has been implemented in the present numerical simulation. ANSYS with certain modifications has been used to account for thermomechanical analysis during laser welding. Temperature-dependent thermal physical properties of 316L austenitic stainless steel have been considered, which influence the temperature profile in the weldment. The temperature distribution was measured at different process parameters. The effect of laser welding process parameters such as average beam power, welding speed, and laser spot diameter on weld bead geometry has been studied. The temperature distribution obtained from the numerical results is in good agreement with the experimental results. The shape of the weld pool profile obtained through numerical simulation is in good agreement with the experimental results.
