METHOD FOR ONE-SIDED RESISTANCE SPOT WELDING

A one-sided resistance spot welding method is disclosed. According to an embodiment of the present invention, provided is the one-sided resistance spot welding method which forms a welding portion in a portion to be welded by applying a current to a welding electrode while pressurizing the portion to be welded of members to be welded with a predetermined pressurization force by the welding electrode after enabling the welding electrode and an earth electrode to be in contact with the members to be welded which are overlapped. The one-sided resistance spot welding method comprises the following steps of: giving a contact force to a gap between the members to be welded by enabling at least one magnet to be in contact with at least one surface on which the members to be welded are overlapped; and resistance spot welding the members to be welded to which the contact force is applied. 편방향 저항 점 용접방법이 개시된다. 본 발명의 실시형태는, 겹쳐진 복수의 피용접 부재에 용접 전극 및 접지 전극을 접촉시킨 후, 상기 용접 전극으로 상기 피용접 부재의 피용접부를 소정의 가압력으로 가압한 채, 상기 용접 전극에 전류를 인가함으로써 피용접부에 용접부를 형성하는 편방향 저항 점 용접방법에 있어서, 상기 복수의 피용접 부재가 겹쳐진 적어도 일면에 하나 이상의 자석을 접촉시켜, 복수의 피용접 부재 간 밀착력을 부여하는 단계; 및 상기 밀착력이 부여된 복수의 피용접 부재를 저항점용접하는 단계를 포함하는 편방향 저항 점 용접방법을 제공한다.
