Abstract：Welding temperature is the key factor for the quality of straight-line welded seam of high-requency electric resistance welded pipe.To improve weld quality of highfrequency electric resistance weld (HFW) pipe，the effects of the main control parameters of welding speed,welding current and pipe thickness on weld quality were discussed for the high-frequency induction heating process. According to the heat equation of high-frequency induction heating process，the proper model of line heat source was established to obtain APDL program based on the thermal analysis module of ANSYS finite element. By adjusting three main control parameters，the welding temperature contour plot was achieved for various parameters. The temperature at welded seam is decreased uniformly at HFW motion direction. With a set of parameters for Ф219 mm high-frequency welding machine of Jinzhou Company，the temperature of temperature field on welding seam was mearured. The results show that the simulation temperature field is consistent with actual temperature field .
