Abstract

본 발명은 용접하고자 하는 한쌍의 플레이트에 형성하는 용접시임의 면적을 확대시켜 줌으로써, 외력에 의하여 파손되는 것을 방지할 수 있도록 하고, 동시에 주사되는 레이저 빔에 의하여 플레이트가 짧은 시간에 융해가 이루어질 수 있도록 하는데에 있는 것으로써, 그 구조는 레이저 빔을 주사하도록 된 제2레이저 토치가 플레이트상에 수직방향으로 설치되고, 이 제2레이저 토치로부터 소정의 거리만큼 이격된 위치에 레이저 빔이 주사될 수 있도록 안내하는 제2렌즈가 제2렌즈 마운트에 결합되어 설치되는데, 상기 플레이트의 상부에 레이저 빔을 주사하도록 된 제1,3레이저 토치가 레이저 빔의 주사를 안내하는 제1,3렌즈를 구비하면서 설치된 레이저 빔을 이용한 용접방법에 관한 것이다.The present invention enlarges the area of the welding seam formed on the pair of plates to be welded to prevent damage by external force, and at the same time the plate can be melted by a laser beam scanned at the same time As a result, the structure is such that a second laser torch adapted to scan the laser beam is installed on the plate in a vertical direction, so that the laser beam can be scanned at a position spaced a predetermined distance from the second laser torch. The guiding second lens is coupled to the second lens mount, and the first and third laser torchs configured to scan the laser beam are provided with the first and third lenses guiding scanning of the laser beam. It relates to a welding method using a laser beam.
