This article uses numerical simulation software to simulate and analyze the forming process of the laser cladding process, and then uses the solikworks 3D modeling software to establish the geometric model of the workpiece, and then imports the drawn model into simufact.mesh.simlab for meshing . Then import the mesh model into simufact.welding welding simulation software to define the process and set its parameters. Finally, the simulation results are analyzed and discussed. Because this article is the technological process optimization, and the important factors that affect the quality of the cladding are the laser power and scanning speed, so focus on changing the scanning speed of the laser and the power of the laser, and then the total deformation and stress of the workpiece after cladding The changes of the field and the temperature value of the lap weld are compared and analyzed to find the most suitable laser process parameters, and strive to obtain an excellent alloy surface for the workpiece to obtain the optimal process parameters.

In this paper, the forming process of laser cladding process is simulated and analyzed by numerical simulation software, and then the geometry of the workpiece is built with the help of solikworks 3D modeling software, and then the drawn model is imported into simufact.mesh.simlab for meshing. Then the mesh model is imported into the simufact.welding welding simulation software to define the process and its parameters, and finally the simulation results are analyzed and concluded. Because this paper is the technology optimization, and the important factor affecting the quality of the cladding is laser power, scanning speed, so focus on changing the laser scanning speed, laser power research, and then the total deformation of the die after the workpiece, the change of stress field and the temperature value at the seam weld for comparative analysis, to find the most suitable laser process parameters, and strive to get the workpiece excellent performance of the alloy surface, in order to obtain the optimal process parameters.

In this paper, numerical simulation software is used to simulate the forming process of laser cladding process, and then the geometric model of the workpiece is established with the help of solikworks 3D modeling software, and then the drawn model is imported simufact.mesh.simlab Mesh. Then import the mesh model to simufact.welding In the welding simulation software, the technological process and its parameters are defined.
