要約(日本語): The TIG arc welding is the high-quality joining technology. However, the weld pool is shallow in the TIG welding because the heat transfer to anode is poor. So, the weld defect sometimes occurs. The pulsed arc welding and mixing oxygen are used in order to control the heat transfer and prevent the weld defect. However, few reports has reported the variation of heat transfer to anode and the physical arc phenomena. In this paper, the time variation of heat transfer to anode in pulsed arc welding was elucidated.
