Study on the deformation of the butt weld by 3D scanning measurement and finite element analysis
In this paper, based on the material properties of SMA490BW steel,the welding deformation of plate butt joint under two typical restraint conditions was analyzed by thermal elastoplastic finite element method. In order to verify the accuracy of the calculation,3-D scanning was used to scan the post welding deformation. The results show that the results of simulation are in accordance with the principle of deformation for plate butt joint. The results of simulation and three-dimensional scanning are in good agreement,which proves that the thermal elastoplastic finite element method can acc-urately predict the welding deformation.
