要望されていた。 In a metal deposition machine using this type of welding equipment, the workpiece is positioned on the base metal and metal is applied by welding while rotating the workpiece, but it is difficult to attach the workpiece to the base metal accurately. If not, welding accuracy will drop significantly. Therefore, in the past, a workpiece mounting recess was provided on the base metal, and the fitting dimensions between the recess and the workpiece were made to be highly accurate, in order to ensure accuracy in the workpiece mounting position. Therefore, when attempting to automate the setting of the workpiece to the base metal, the workpiece could not fit into the recess of the base metal, often resulting in defective products. For this reason, the current situation is that most workers manually fit the workpiece into the recess, and there has been a demand for complete automation of this type of automatic metal-plating machine.
