Deformation must be induced forcibly in order to compensate for the warpage that occurs during welding of large plates used in large structures. In the existing process, a powerful pushing jack was inserted between the support that acts as a pedestal and the plate that needs correction, and the process of correcting the plate was performed. When adjusting the steel plate to be welded, Jaw teeth are lodged in the iron plate and the bottom surface. In order for the teeth embedded in the steel plate to transmit sufficient force, the jaw should be designed to have an optimal tooth shape. In this study, the structural analysis technique was applied to design the tooth shape of the jaw to transmit the force required by the teeth embedded in the steel plate. The optimal tooth shape was selected by comparing the stress distribution and deformation amount due to the applied force for the three tooth shapes of jaw.
