Zusammenfassung:	An objective of the present invention is to provide a friction stir welding machine and a friction stir welding method using the same, which prevent concentration of frictional heat directly below a shoulder. According to the present invention, the friction stir welding machine comprises: a device frame equipped with a rotary driving member; and a joining tool having a shoulder and a probe installed on the device frame. The shoulder and the probe are made of a non-integral structure so that only the probe is rotated by the operation of the rotary driving member. A portion of the joining tool in contact with a welding target surface of a welding material is inclined upward in a radial direction. 본 발명에 따른 마찰교반용접기는, 회전구동부재가 장착된 장치프레임; 및 상기 장치프레임에 설치된 숄더와 프로브를 가진 접합툴;을 포함하며, 상기 회전구동부재의 작동에 의해 상기 프로브만 회전되도록 상기 숄더와 프로브는 비일체형 구조로 이루어지고, 용접소재의 용접대상면에 접하는 상기 접합툴의 부분이 방사방향으로 상방경사지게 형성된다.
