Abstract

Abstract At present, the traditional welding temperature field and stress prediction mainly rely on the experience curve or empirical formula based on experiment and statistics, which cannot comprehensively predict and analyze the impact of welding on the overall structural mechanical characteristics and objectively evaluate the welding quality. In this paper, based on simulated welding software, the temperature field stress field and residual stress deformation after welding are simulated by the finite element method, and a set of feasible 3D welding temperature field calculation methods, stress field, and deformation dynamic simulation analysis methods are established.
