Simulation on Ring Welding Temperature Field for Ring Welding Seam of Coiled Tubing

The coiled tubing ring seam 3D welding temperature field numerical analysis model was set up by finite element software ANSYS.The double ellipsoid heat source distribution model was imported,and the corresponding APDL programs were developed.The backing welding temperature field curve was calculated.The simulation results are basically consistent with experiment results,which show that the method can accurately calculate the welding temperature field.
