Abstract

A method for spot welding includes applying preset welding heat input to a welding device in correspondence to a welding base material positioned at the welding device by a controller, applying the preset welding heat input to the welding position by moving the welding device by the controller, measuring height variation of the applied welding position through an encoder, and providing target heat input by compensation for a current value that is applied to the welding position by comparing real-time height variation of the welding position measured through the encoder and a gradient set in the controller.
