Finite Element Simulation on Micro-Forging Process Inhibiting Warping of the Thin-Walled Components Treated by Laser Cladding

During the process of laser cladding thin-walled components, warping deformation generated on the thin-walled components due to the difference between the change of temperature field and thermal expansion coefficient of materials. Through the micro-forging regulation, the internal stress of laser cladding layers changed, reaching the purpose of suppressing the warping plastic deformation generating on the thin-walled components. This paper utilized Ansys software to calculate the temperature field and stress field of the process of laser cladding 304 stainless steel regulated by micro-forging, and compared to the measurement result of the warp deflection and stress. The results indicated that reasonable effective micro-forging can effectively restrain the warp occurring on the thin-walled components treated by laser cladding.
