The welding with weaving has been used widely to obtain better weld quality by avoiding lack of side wall fusion and improve the weld efficiency by obtaining the wide weld bead. But the effect of weave frequency and weave amplitude on the temperature field is not clear. In the present paper, a coordinate transformation method is put forward to simulate the weave welding process. The temperature distribution during the welding with weaving under different weave parameters are compared and discussed. Comparison between experimental and simulation results reveals a good agreement. The peak temperature and the average temperature in weld seam center decreased due to the increasing of the weave amplitude and weave frequency. But the weave frequency has less effect on the average temperature.
