Abstract
AbstractBased on ANSYS APDL, this paper simulates the welding process of the safety end of the pipe using different heat source models. The results show that the shape of the moving heat source under the body heat rate heat source model and the double ellipsoid heat source model is ellipsoidal shape. The body heat rate heat source has a larger high temperature area than the double ellipsoidal heat source. The variation law of temperature field and stress field is basically the same, but the overall stress field under double ellipsoid heat source load is about 20 MPa smaller than the total stress field under body heating rate. The comparison of different heat source models can provide some help for the numerical simulation of welding.
