Abstract: A method for working a first component and a second component comprises the following steps: providing the first component, which comprises a thermally sprayed electrically conductive layer, providing the second component, which has a longitudinally extended strip of copper, which at least in a first region has a thickness transversely to the longitudinal direction of more than 0.1 millimeter, arranging the strip and the layer one on top of the other, so that the first region of the strip and the layer have a contact region in common with one another, emitting a laser beam onto the contact region and forming a welded connection, which connects the strip and the layer to one another.

Abstract: An electric heating device includes a substrate and a heat conductor layer formed on the substrate. The heat conductor track includes a plurality of track sections which run adjacently to one another and are separated from one another by insulating interruptions. At least one reversal point is provided at which the heat conductor track is deflected such that inner track sections with opposite flow directions run adjacently and parallel to one another. The spacing between the adjacent inner track sections is locally expanded in the region of the reversal point where the inner track sections protrude outwards to outer track sections, and the width of the track sections is locally reduced in front of and in the outer track sections to compensate for the local expansion on the inner face between the inner track sections and for the protrusion of the inner track sections.

Abstract: An apparatus for a heating device for a vehicle comprises a layer stack which, in a stacking direction, has a heating conductor layer, an electrically conductive layer which forms a contact region, wherein a contour in a projection in the stacking direction of the electrically conductive layer is prespecified, in order to prevent a hotspot on the electrically conductive layer, by at least one of a prespecified width of a front side of the electrically conductive layer which faces a central region of the heating conductor layer, a prespecified distance from a joint of the heating conductor layer, and a prespecified curvature of the contour.
