Claims

[Scope of utility model registration request]

It has a guide protrusion on the upper part of the metal pin body, is provided on the lower electrode side so that it can move up and down, and when the plate material is transferred onto the lower electrode, it penetrates through the screw insertion hole formed in the plate material and protrudes. A screw hole of a nut is fitted into the guide protrusion to weld the nut and the plate material between the upper electrode and the lower electrode, wherein at least the outer surface of the guide protrusion is made of ceramic. A guide pin for a nut welding device characterized by being provided with a thermally sprayed layer.
