Abstract

알루미늄 도금 강판을 용접하여 탱크 등을 제조할 경우에, 도장(塗裝)의 후처리공정이 불가결하여 내면측의 내식성(耐食性)에 문제가 있다. 본 발명에 따르면, 양면이 알루미늄으로 도금된 알루미늄 도금 강판으로 된 상하 한쌍의 반각체(半殼體)(2,3)의 주변 플랜지부(2a,3a)를 용접하여 연료 탱크(1)를 제조함에 있어, 한쪽의 플랜지부(3a)에 계단부(d)를 마련하고, 이 계단부(d)에 의하여 형성된 틈부분으로 향하여 레이저 광을 조사하여 용접한다. 그리고, 겹쳐 맞추어진 면폭(대향면측)에서 발생하는 Al 등의 불요 성분을 상기 틈으로 도피시켜, 용접부(y)에 혼입되는 Al 등의 양을 저감시켜 용접 강도의 향상을 도모한다.
