Abstract
A 3D parametric model was established for the die steel whose matrix material was H13. Ni60 alloy powder was used to cladding the matrix, and a single-layer multichannel finite element model of heat-force coupled laser was established. The laser power P=600W, scan rate v=20mm/s, laser spot radius R=1mm were selected as simulation parameters. The temperature field and stress field in the process of laser cladding are analyzed by finite element method.
