    • Abstract
  • The welding process of frequently-used T-shaped pipe in heating transportation pipeline was numerically simulated. Based on the SYSWELD software platform, the double ellipsoid heat source distribution model was used. Firstly, the three-dimensional model was built by UG and the mesh for the model was divided by hypermesh, then the welding process was simulated by SYSWELD. The distribution of temperature and stress-strain fields were obtained. The temperature contour and the overall deformation of the welding parts in the welding process were analyzed in details. The results show that the temperature of the heat source can reach as high as 2500℃. The heat affected zone is obviously formed around the weld. Stress concentration appears in the weld area. The maximum stress is 277 MPa, which is within the material's yield stress that is 345 MPa. The phenomenon of concave is appeared in the weld. The maximum deformation is 0.29 mm. The analysis provides a theoretical basis for the actual welding.
