Abstract

Aiming at the Mag welding between the drive axle housing and the axle tube of commercial vehicles, the finite element numerical model of the welding process was established by using the finite element software Sysweld. Combined with the actual welding process parameters and the thermophysical and mechanical performance parameters of the material, an appropriate heat source model was selected, and the simulation results of the welded joint and the actual molten pool morphology were compared to verify the correctness of the heat source model. The temperature distribution cloud diagram of the welded joint at different times and the thermal cycle curve of the key nodes were obtained by analysis. By comparing the test results with the numerical simulation results, the reliability of the numerical simulation of the axle tube and the axle housing was proved. When analyzing the axial residual stress and circumferential residual stress of the welded joint, it was found that the peak value of residual stress was located at the welding root, which is consistent with the actual failure position of the axle housing.
