Abstract: A method for soldering or welding components in a series production wherein: a fixing seam which connects the components (1, 2) is produced by melting a connecting material (3), which is supplied as an additional material or is formed by a base material of the components (1, 2), along a joint formed by the components (1, 2); and a volume-forming layer of connecting material is deposited onto the fixing seam by melting, or the fixing seam produced by means of the connecting material supplied as an additional material is re-melted.

Abstract: A joining surface treatment device and a joining surface treatment method for treating a joining surface of a component which joining surface is used for joining two components, the joining surface treatment device comprising at least one heat source for heating a portion of a surface of a first component at which portion the first component shall be joined with a second component; and a primer application device for applying a primer to a portion of the surface of the first component which portion is heatable by the at least one heat source, wherein the at least one heat source is arranged so that it can heat the first component before and/or after applying the primer.

Abstract: A composite of sheet metal parts on or for a vehicle comprises a first sheet metal part forming a first outer shell region and comprising a first joining region which projects from the first outer shell region via a bent transition towards an inner side of the composite. The composite further comprises a second sheet metal part forming a second outer shell region and comprising a second joining region which projects from the second outer shell region towards the inner side of the composite, the second joining region facing the first joining region. The composite also comprises a welding or soldering seam along which the sheet metal parts are connected, wherein the seam runs along or alongside a flange edge formed in the first joining region at a distance from the first outer shell region, a flange deviating from the first joining region along the flange edge.

Abstract: A roll-flanging tool, including a bearing structure having a connector, by which the tool can be connected via a connection plane to an actuator which can be moved spatially. A first arm and a second arm are spread apart from each other and connected to each other in a connection portion which includes the connector. A first flanging roller is mounted on an end of the first arm which faces away from the connection plane, such that it can be rotated about a first rotational axis which extends along the first arm and pierces the connection plane. A second flanging roller is mounted on an end of the second arm which faces away from the connection plane, such that it can be rotated about a second rotational axis. The first rotational axis intersects or crosses a perpendicular dropped onto the second rotational axis, in or on the roll-flanging tool.

Abstract: A monitoring device (10) for a laser machining device (12) that has one or more laser beams (13) that are displaced along a predetermined adjustable trajectory (14, 16) along a workpiece (18) includes one or more sensors (20, 22) which monitor(s) the processing signal (24) of the machining process in a three-dimensional section (26). The one or more sensors (20, 22) activate an alarm device or interrupter (28) for the one or more laser beams (13) of the laser machining device (12) if the one or more process signals (24) in the section (26) exceed a predetermined threshold value or fall short of it, the one or more sensors (20, 22) being independent of the laser machining device (12).

Abstract: The invention relates to a device for shielding coherent electromagnetic radiation, especially laser radiation. The device comprises at least two partially converging faces (6, 7) between which two opposite openings (8, 9) are configured. The distance of the faces (6, 7) between the two openings (8, 9) varies to such an extent that the electromagnetic radiation is prevented from going from the one opening (8) straight through the other opening (9).
