In these years, connecting wires are being more complicated in home electric appliances and cars are being more electrically equipped. Against these trends, fusing is being applied more frequently as a joining method between electrical parts and wires, where partial melting and plastic deformation occur simultaneously in the core and surroundings in the junction, respectively. For fusing, spot welding machines are used with tungsten or molybdenum electrodes. Since the work is usually highly electrically conductive such as copper and aluminum, resulting in extremely large electric current, degradation of the electrodes is prone to occur, whereas the mechanism. In this study, the microstructure of the electrodes was closely observed by SEM, and attempts were made to elucidate the degradation mechanism.
