。[Scope of Claim for Utility Model Registration] (1) When multiple workpieces made of formed steel plates are overlapped and spot welded by sandwiching them between electrode chips from both sides, there is no intervening between one electrode chip and the workpieces. The deformation prevention plate has a main body made of a heat-resistant synthetic resin, and has a mating surface having a shape corresponding to the shape of the joint on one side of the workpiece, and also has a mating surface corresponding to the shape of the joint part on one side of the workpiece, and also has a mating surface corresponding to the spot dot portion of the workpiece. A through hole is provided at the position where the copper chip plate is placed, and a chip steel plate is removably disposed in the through hole, and the tip surface of the chip copper plate and the mating surface are formed in the same plane. Features a deformation prevention plate for spot welding. (2) In the deformation prevention plate according to the first claim,
A deformation prevention plate for spot welding, characterized in that the chip copper plate is disposed such that its tip surface is movable in a direction protruding from the mating surface of the main body. (3) In the deformation prevention plate according to the first claim,
A deformation prevention plate for spot welding, characterized in that the chip copper plate is arranged in a through hole of a main body so that its position in the front and back direction can be adjusted by screwing means.
