알루미늄 합금의 겹치기 마찰교반용접시 프로브 형상과 판재 위치가 기계적 강도에 미치는 영향에 관한 연구 = A study on the effect of probe shape and plate position on the mechanical strength during lap joint friction stir welding process of aluminium alloys

다국어 초록 (Multilingual Abstract)

Unlike the existing melting welding process, Friction Stir Welding(FSW) is an environmental-friendly solid phase welding process that is used for welding light metals such as aluminium alloys, which exhibits less deformation by thermal stress, and does not generate toxic gases. This paper performed lap joint welding for aluminium alloy through friction stir welding process. During the welding process by using a threaded cylindrical probe tool, defects occurred on the welding surface in respect to the rotating direction of the tool.
