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

摘要：

　　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.
