Numerical Simulation and Experimental Study of D-Arc Deep Penetration Welding in Straight Seam of Commercial Vehicle Axle Housing
Journal Title: Automobile Technology & Material - Year 2024, Vol 39, Issue 3
Abstract
The D-Arc deep penetration welding process was applied to the straight joint welding test of 12 mm-thick axle housing of commercial vehicles, and the weld profile, welding thermal cycle and residual stress were measured and analyzed. Based on Simufact Welding software and combined with the profile shape of the welded joint, a finite element analysis model for straight seam welding of the axle housing was established. A composite heat source model of Gaussian surface heat source and cone heat source was adopted to simulate the heat input in the D-Arc deep penetration welding process, and the process of straight seam D- Arc deep penetration welding was numerically simulated. The temperature and stress distribution of the axle housing at different times were obtained, and the simulation results were basically consistent with the test results, which verified the reliability of the finite element analysis model, and also proved the feasibility of D- Arc deep penetration welding process in the welding scene of commercial vehicle axle housing.
