Abstract
The present invention can weld two parts of component metal fitting constituting the parts as a welding apparatus used in manufacturing automotive parts such as a strut mount upon positioning and laminating. Furthermore, a welded part can be easily recovered to improve the operationality of welding. This welding apparatus has support tables to support two parts of component metal fitting. The support table has thereon a positioning pin provided standing in a position corresponding to the penetration holes possessed in the both parts of component metal fitting and a lower electrode to support the two parts of component metal fitting in their joining points. In a position further above thereof, an upper electrode is provided that is held vertically movable. The positioning pin in its upper end is made in a tapered form. The pin is supported elastically pressed down by spring means. Furthermore, urging means is provided to press down the pin against the spring means separately from the upper electrode. Due to pressing down of this urging means, the pin is pressed down from a state that the tapered upper end is positioned above the penetration hole of the parts of component metal fitting supported by the lower electrode. The pin and the penetration hole at its peripheral edge are to be disengaged.
