用ガイドピン。 The metal pin body has a guide protrusion at the top, which is movable up and down on the lower electrode side, and projects through a screw insertion hole formed in the plate when the plate is transferred onto the lower electrode. The nut and the plate are sandwiched and welded between the upper electrode and the lower electrode by fitting the threaded hole of the nut into the guide protrusion, and the guide protrusion is made of a high-quality material such as alumina or zirconia. A guide pin for a nut welding device, characterized in that it is made of strong ceramics and a ceramic sprayed layer is provided on the outer surface of the pin body.
