PURPOSE: A two-dimensional flexible fixing member is provided to control an angle and a position of a welding line profitably. CONSTITUTION: A two-dimensional flexible fixing member for a butt laser welding contains a welding fixing member composed of an upper fixing member and a lower fixing member; a curve guide and a horizontal guide installed on a welding table(10) to rotate the welding fixing member according to positional changes of welding lines(4,4') between plates(1,1',1") for welding on the lower fixing member. The welding fixing member comprises an oblique fixing member(13) to be rotated by the curve guide and a rectilinear fixing member(17) to horizontally moved by the horizontal guide. The oblique fixing member(13) and the rectilinear fixing member(17) suppress and fix the plates(1,1',1") to be inserted between the upper fixing member and the lower fixing member by suppressing force of the upper fixing member. 본 발명은 맞대기레이저용접을 하기 위한 판재고정용 장치로서 두 용접선이 이루는 각도와 위치를 조절하여 2개의 용접선을 동시에 고정하여 용접할 수 있는 맞대기레이저용접용 2차원 유연고정구에 관한 것이다. 본 발명의 일실시예인 맞대기레이저용접용 2차원 유연고정구는 용접용 판재의 용접선이 하나일 경우는 물론, 승용차의 사이드도어프레임과 같이 사선 용접선과 직선 용접선을 함께 구비한 세 개의 판재를 동시에 용접할 필요가 있을 때에도 사선의 각도와 직선위치를 임의로 조정하여 유연생산이 가능하도록 하며, 동시에 세 판재를 고정하여 용접할 수 있다는 뛰어난 효과가 있다.
