Abstract

레이저 용접을 이용해서 금속띠로부터 용접관을 제조할 때에 레이저 용접전의 금속띠 끝부의 온도가 소정온도 이상이 되도록 금속띠의 끝부를 미리 가열해서 예열한 금속띠의 끝부끼리를 레이저 용접하여 제관하고 제관한 용접관의 외면 및/또는 내면의 용접비이드를 절삭에 의해 제거한다. 이 소정온도는 금속띠의 두께 및 레이저 용접으로부터 용접 비이드 절삭까지의 시간에 대응해서 결정한다. 제조한 용접관의 용접비이드를 절삭할 수 있도록 용접전의 금속띠 끝부를 예열해 두고, 레이저 용접후의 용접부의 급냉에 따르는 용접비이드의 경화를 방지한다.
