Abstract

The pipeline steel X70W submerged-arc welding was simulated by FEM using ANSYS, for the issue that the cracks were frequently found in the base metal when the pipeline steel was expanded holes after welding. And the residual stress was analyzed at three different welding speed through temperature field distribution and stress field simulating, a conclusion was obtained that the residual stress reduces as the welding speed reduces.
