Zusammenfassung:	Provided is a spot welding method including the steps of: preparing a base material to be spot welded; pressurizing the prepared base material with an electrode and maintaining the pressure; securing a passage through which a current is applied to the base material by applying a first current to the base material through the electrode; spot-welding the base material by applying a second current to the base material through the electrode; cooling the spot-welded base material; and releasing the pressure applied to the base material. 점 용접할 모재를 준비하는 단계; 준비한 모재를 전극으로 가압하며 압력을 유지하는 단계; 전극을 통해 모재에 제1전류를 인가하여 모재에 전류가 인가되는 통로를 확보하는 단계; 전극을 통해 모재에 제2전류를 인가하여 모재를 점 용접하는 단계; 점 용접된 모재를 냉각하는 단계; 및 모재에 가해지는 압력을 해제하는 단계;를 포함하는, 점 용접 방법이 소개된다.
