Claims

[Scope of utility model registration request]

A plate to be welded having a through hole and a nut to be welded to the plate to be welded corresponding to the through hole between a fixed electrode and a movable electrode which is disposed facing and capable of moving toward and away from the fixed electrode. In a nut welding device in which a guide pin is supported by a fixed electrode, the guide pin is disposed with the nut facing the movable electrode, and the guide pin protrudes through the through hole to insert into the nut for positioning. movable and supported by the fixed electrode and biased in the direction of protrusion;
The guide pin is provided with an engaging portion that engages with the nut when inserted, and the fixed electrode is equipped with a detector that detects the guide pin when the nut is pressed toward the fixed electrode by the movable electrode. Characteristic nut welding equipment.
