The Numerical Simulation on Welding Stress Field of High Strength Steel for Axle Case Steel 390Q
This paper takes the butt joint of axle case steel as research object, simulates the real-time three dimensional dynamics CO2 shielded welding of welding stress field by FEM software ANSYS and obtains the axle case steel 390Q’s transient stress field of weld zone at different welding speed. On that basis, the feasible dynamic simulation method of three-dimensional stress welding field which provides theoretical basis and guidelines for optimizing welding technology and norm welding parameters was proposed. The result of welding stress simulation shows that the welding stress is the lowest when the optimum welding speed is 5mm/s.
