Abstract
PURPOSE:To facilitate charging parts and taking out a weld-finished product by constituting supporting pins to hold respective cylindrical members at the prescribed positions of split pins and providing core pins to be inserted into the split pins to expand the diameters. CONSTITUTION:The plural cylindrical members 17 for spacers are arranged lengthwise and crosswise on a welding bench 10 and the split pins 13 provided to the welding bench 10 are inserted into the spaces formed by the four cylindrical members 17 to adjoin to one another. When a reference base 14 is moved upward to the upper limit position, the core pins 16 are inserted into the split pins 13 which are expanded. Accordingly, the cylindrical members 17 to adjoin to one another by the outside peripheries of the split pins 13 are properly restrained at intervals of the length and breadth, etc., and adjacent parts of the respective cylindrical members 17 are welded. On the other hand, when the welding is finished and the reference base 14 is moved to the lower limit position, the core pins 16 are extracted from the insides of the respective split pins 13 and the expanding forces of the outside diameters of the respective split pins 13 are released. Accordingly, the weld-finished product can be easily extracted from the split pins 13 of the welding bench 10.
