In order to explain the phenomenon in laser welding melted. Through the heat conduction and thermal deformation plate heat elastic-plastic explained. Using finite element method(FEM) for 3D nonlinear heat conduction explanation. Experiments to achieve a good welding process and result. On the heat distribution, thermal deformation and residual stress three aspects to conduct an investigation. Eventually, Using finite element to the welding deformation forecast. Should look to build hot delivery and hot elastic-plastic explanation. And So that the needs of various processing. Combined with welding predecessor essence. For a good prediction performance to verify and review. And to get the last occurrence good results.
