  • Patent number: 11179897
    Abstract: A laser joining method and device includes a pressure-applying clamping device, which presses a first and a second workpiece against one another at least after the workpieces have been locally plasticized, and a mask having mask structures, which allow laser light to pass only in the region of the bonding contact faces, wherein at least the workpiece facing the laser source is formed by a three-dimensional molded part, which is not planar at least on the first contour side facing the clamping element and/or on the second contour side facing the second workpiece, and wherein the clamping element, with the bearing side thereof for the first workpiece, is adapted to the first contour side of the first workpiece. The mask structures are created on the bearing side of the clamping element facing the first workpiece or on the second contour side of the first workpiece facing the second workpiece.
