  • Patent number: 11612955
    Abstract: A joining device and method for laser-based joining of two components includes a first laser radiation source, a first radiation guide connected to the first radiation source to couple first laser radiation into the first radiation guide, a second laser radiation source, at least one second radiation guide connected to the second radiation source to couple second laser radiation into the second radiation guide, and a focusing device coupled to the laser radiations and focusing them at a distance from each other into a joining zone of the components. To reduce installation effort, the focusing device focuses the first and second laser radiations through a common beam path and a coupling device is connected on its input side to the first and second radiation guides and on its output side to the focusing device. The coupling device couples the first and second laser radiations into the common beam path.

  • Patent number: 11383325
    Abstract: The invention relates to a method for the generative production of at least one component, a device for performing the method and a motor vehicle, in particular a passenger car. In a method for the generative production of at least one component, a powder of a material is irradiated by means of laser radiation so that it is heated and at least partially melted and the molten material solidifies in order to at least partially form the component. Information relating to the temperature of the material irradiated and/or to be irradiated, in particular thermal radiation, is detected and used for influencing the laser intensity. The laser radiation is conducted at least in sections by means of a light guide to the material and the information relating to the temperature is transmitted in the inner region of the light guide for the purpose of its detection.

  • Publication number: 20150314392
    Abstract: The invention relates to a method by which stitch welds (5) can be produced on the front faces of metal sheets (preferably on flanges) by means of laser welding. In order to produce the stitch weld seam, the following steps are repeated cyclically: pre-heating the joining partners (1, 2) in an area in front of the stitch weld seam to be produced, producing a short stitch weld section (7) at a relatively low resulting welding speed, and producing a section without a weld seam, as a result of which in each case an intermediate space (9) is formed between neighbouring stitch weld sections (7). The ratio of the lengths (6, 8) of intermediate spaces (9) and stitch weld sections (7) is selected in such a way that a degassing is achieved to such an extent that a high quality of the stitch weld seam (5) is achieved. The method is particularly suitable for producing welded joints between galvanized, heat-treated steel sheets, as are often used in automobile manufacture/vehicle body construction.

  • Patent number: 6568868
    Abstract: A fastening arrangement for joining sheet metal car body components has a locating surface on which the car body components are supported and has a fastening component that is movable in the direction toward the locating surface and can be fixed in relation to that surface and includes compression elements cooperating with a pneumatic or hydraulic pressure membrane. The fastening component advantageously pivots around a rotary joint that can be locked in relation to the locating surface. Both the fastening component and the locating surface can have three-dimensionally formed 3D contours.
