Abstract: A method and device for joining coated metal sheets by laser welding is provided in which the metal sheets (1, 2) are placed one on top of another such that the marginal strip (4) of one metal sheet (2) protrudes over the marginal strip (3) of the other metal sheet (1). The marginal strips (3, 4) are pressed together at least in some areas and are joined by laser welding with a laser beam (14) directed at right angles or at about right angles to the plane of the marginal strips (3, 4). The protruding marginal strip (4) is pushed away from the other marginal strip (3) during the laser welding to form a degassing space (10).

Abstract: A processing station in motor vehicle assembly lines has two receiving frames (20), for a motor vehicle part (33), which are mounted on associated columns (2, 3) at mutually spaced locations in a synchronously height-adjustable manner and are synchronously revolvable about mutually aligned horizontal axes of rotation. Each receiving frame (20) is mounted on two said columns (2, 3) arranged on both sides of the axis of rotation and that the mutual distance between the columns (2, 3) is greater than the width of the motor vehicle part (33) or of a transport element (29) for the motor vehicle part (33).

Abstract: The invention relates to a method and a device for installing door hinges on car bodies, whereby the actual opening width of the car door on the side frame receiving one or two car doors in the longitudinal car axis is touch-sensitively determined by means of a sensor in a direction X and the arrangement of the door hinges is adjusted in said direction X using a positioning system connected to the sensor by a cranking device, depending on the tolerance margin, which should be calculated so as to have at least vertically (direction Z) as uniform a slot width as possible once the car door is mounted.
