摘要: Finite element (FE) simulation with inherent deformation is an ideal and practical computational approach for predicting welding stress distortion in the production of complex aluminum alloy structures. In this study, based on thermal elasto-plastic analysis, FE models multi-pass butt welds T-type fillet were investigated to obtain strain distribution a 5A06 cylindrical structure. The angular joint was used investigate corresponding mechanism. Moreover, custom-designed experimental system applied clarify magnitude deformation. With mechanism investigation welding-induced buckling by analysis using deformation, application mitigating fabrication structure developed.
