ABSTRACT

A simple 3D model was used to simulate the process of laser cladding for the case of 316L stainless steel powder coating on the 45 steel. Effect of overlap rate on the temperature field was discussed using numerical simulation results. Isothermal contours for each substrate showed approximate ellipse shape, which distribution was changed significantly by adjustment of overlap rate. Furthermore, history of temperature load, such as peak temperature and thermal cycle was different for each substrate region, but all temperature amplitude was increased by the raise of overlap rate.
