Abstract:
(EN) Disclosed is a method capable of optimizing laser welding of different kinds of metals by using a quantitative analysis of a binding structure of an intermetallic compound generated from a laser welding portion. The method comprises a step for optimizing welding conditions by measuring content of an intermetallic compound generated at a laser welding portion of different kinds of metals, and by calculating a ratio of a molten area of each of the different kinds of metals and controlling the same with a predetermined value.
(FR) Procédé permettant d'optimiser le soudage au laser de différents types de métaux à l'aide d'une analyse quantitative d'une structure de liaison d'un composé intermétallique produit à partir d'une partie de soudage au laser. Le procédé comprend une étape consistant à optimiser des conditions de soudage par la mesure du contenu d'un composé intermétallique produit au niveau d'une partie de soudage au laser de différents types de métaux, et par le calcul d'un rapport d'une zone fondue de chacun des différents types de métaux et la régulation de celui-ci avec une valeur prédéfinie.
(KO) 레이저 용접부에 발생하는 금속간 화합물 결합 구조의 정량적 분석을 이용하여 이종 금속의 레이저 용접을 최적화 할 수 있는 방법이 개시된다. 상기 방법은 이종 금속의 레이저 용접부에 생성되는 금속간 화합물의 함량을 측정하여 이종 금속 각각의 용융 면적 비율을 산출하고 이를 소정 값으로 제어함으로써 용접 조건을 최적화하는 단계를 포함한다.
