要約(日本語): High-quality welding is performed by technicians. However, the number of technicians is decreasing. As a countermeasure, it has been suggested that the control of heat input to the base metal with applying a magnetic field. However, few analyses of arc have considered welding torch movement and the application of magnetic fields. In this research, the arc temperature distribution was analyzed with applying an alternating magnetic field in welding torch movement. As a result, the melt volume under the condition with an external magnetic field was larger than that under the condition without an external magnetic field. Therefore, it is suggested that the melt volume increased because the magnetic field application created a temperature distribution that increased the heat input to the base metal.
