Abstract: In the process of multi-layer laser cladding of H13 die steel, the residual stress of the cladding layer after laser cladding is reduced by presetting the surface texture. Firstly, the surface was pretreated, the square surface texture was preconfigured, and the laser cladding process was simulated by the APDL language of Ansys software, and the temperature field and stress field in the cladding process were analyzed and studied. Secondly, the influence of preset texture on the temperature field and residual stress of the laser cladding layer is studied by orthogonal simulation results. Finally, the experiment was carried out. The research results show that the average analysis of the orthogonal simulation experiment results shows that the optimal cladding parameters are laser power P = 400 W, scanning speed v = 20 mm/s, and laser beam radius R = 0.8 mm, and the sequence of factors affecting residual stress of cladding layer is laser power > laser beam radius > scanning speed. A comparison between the results of simulations and the actual processing results under optimal parameters showed a 25.96% reduction in residual stress on the surface of cladded workpieces with textures compared to those without textures in simulations, and an 18.55% reduction in residual stress on the surface of cladded workpieces with textures compared to those without textures in actual processing. Therefore, the application of pre-setting textures on the surface of H13 mold steel has been demonstrated to effectively reduce residual stress within the cladding layer, thereby minimizing or eliminating crack formation. This has been shown to play a positive and effective role in the mold remanufacturing process using laser cladding.
