Description

최소한 한쪽면 이상이 아연도금된 디이프 드로윙 철판 또는 철편의 버트 용접방법Butt welding method of deep drawing steel sheet or iron sheet galvanized on at least one side

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제 1 도 및 제 2 도는 본 발명의 실시예를 보인 버트 용접(butt-welding) 장치의 단면도임.1 and 2 are cross-sectional views of butt-welding apparatus showing an embodiment of the invention.

Claims (8)

판상체 또는 설편상에 세로방향으로 0.04mm 이하의 파형을 가진 절단부가 형성되고, 이 판상체 또는 설편을 이들 절단부와 접촉되도록 이송시킨 다음 0.2mm이하의 지름을 가진 절단부를 덮는 체점을 가진 레이저 비임에 의하여 서로 용접함을 특징으로 하는 최소한 한쪽면이 아연도금된 철판 또는 철편을 반드시 장방형의 절단부를 가진 레이저 비임에 의하여 용접시임이 부식으로부터 보호 받도록 하는 버트 용접 방법.A laser beam having a body point formed on the plate or tongue with a wave length of 0.04 mm or less in the longitudinal direction, the plate or tongue being brought into contact with these cuts and then covered with a cut having a diameter of 0.2 mm or less. A butt welding method in which a welding seam must be protected from corrosion by a laser beam having a rectangular cutout of at least one galvanized iron plate or a piece of steel, characterized by welding each other. 제 1 항에 있어서, 서로 용접될 판상체 또는 설편이 용접시임의 양측과 그 전체의 길이를 통하여 용접하는 동안 냉각되고 용접에 의해서 영향을 받는 부분은 1mm 이하의 폭을 갖는 것을 특징으로 하는 방법.The method according to claim 1, wherein the platelets or tongues to be welded to each other are cooled during the welding through both sides of the welding seam and the entire length thereof, and the portions affected by the welding have a width of 1 mm or less. 제 1 항에 있어서, 판상체 또는 설편을 양쪽에서 냉각시킴을 특징으로 하는 방법.The method of claim 1 wherein the platelet or tongue is cooled on both sides. 제 1 항에 있어서, 용접시임의 후면이 보호가스 기류중에 놓여있음을 특징으로 하는 방법.The method of claim 1 wherein the backside of the weld seam lies in a protective gas stream. 제 1 항에 있어서,용접부의 후면(저면)에 여분의 압력이 가해짐을 특징으로 하는 방법.The method of claim 1, wherein extra pressure is applied to the rear face (bottom face) of the weld. 제 1 항에 있어서, 서로 용접되는 판상체가 용접부 바로 다음에 놓여 있는 냉각된 용접 죠우에 의하여 용접하는 과정의 한 위치에 놓여 있음을 특징으로 하는 방법.2. A method according to claim 1, wherein the platelets to be welded to each other are placed in a position in the process of welding by a cooled welding jaw placed immediately after the weld. 제 1 항에 있어서, 상이한 두께, 특히 0.5mm 내지 0.3mm 사이의 두께를 가진 판상체 또는 설편이 용접과정에 상대적인 위치내의 단부에 놓여있고, 레이저 비임으로부터 떨어져 있는 후면 또는 레이저비임쪽으로 향한 판상체 또는 설편의 전면이 반드시 같은 평면내에 놓여있는 것을 특징으로 하는 방법.2. A plate or body according to claim 1, wherein a plate or tongue with a different thickness, in particular between 0.5 mm and 0.3 mm, lies at the end in a position relative to the welding process and faces toward the back or laser beam away from the laser beam or And the front face of the tongue must lie in the same plane. 제 1 항에 있어서,상이한 두께, 특히 0.5mm 내지 0.3mm 사이의 두께를 가진 판상체 또는 설편보다 더 두꺼운 판상체 또는 설편은 절단부에 인접해 있는 전면 또는 후면의 적어도 한 모서리를 죽여서 두께를 엷게 하는 것을 특징으로 하는 방법.The platelets or tongues thicker than the platelets or tongues of different thicknesses, in particular between 0.5 mm and 0.3 mm, are thinned by killing at least one edge of the front or back surface adjacent to the cutout. Characterized in that the method. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
