Abstract: Described herein is a method for laser welding of a rim to the disk of a wheel for motor vehicles, in which the rim envisages a circumferential wall, with an internal surface, and the disk envisages a circumferential portion, which is in contact with said internal surface of the rim and has a circumferential end edge, said method comprising the operation of focusing the laser beam in the area of contact between the circumferential portion of the disk and the internal surface of the rim, in a position corresponding to the circumferential end edge of the disk.

Abstract: The invention relates to a side door of a passenger vehicle, which for opening purposes, following a sideways movement which moves the side door out of the door aperture, is actuated by auxiliary forces to pivot forwards and upwards around a horizontally aligned, bodywork-mounted bearing point, and it is proposed, in order to provide quick release from the A-pillar and to create the preconditions for a conveniently operating movement mechanism with expedient accommodation for the latter, that in the horizontal plane, in relation to the transverse direction of the vehicle, the pivot axis of the bearing point respectively runs at an angle, which does not exceed for example 25.degree. in each case, in the anticlockwise direction on the left-hand side and in the clockwise direction on the right-hand side.

Abstract: A robot for welding motor-vehicle bodies or subassemblies thereof is provided with a head for carrying out wire resistance seam weldings. The welding head includes a pair of counter-rotating welding rollers through which an electric current is passed. A copper wire is fed continuously around the welding rollers.
