Abstract:
A method for working a first component (101) and a second component (102) comprises the following steps: providing the first component (101), which comprises a thermally sprayed electrically conductive layer (103), providing the second component (102), which comprises a longitudinally extended strip (104) of copper, which at least in a first region (112) has a thickness transversely in relation to the longitudinal direction (106) of over 0.1 millimetre, arranging the strip (104) and the layer (103) on one another such that the first region (112) of the strip (104) and the layer (103) have a common contact region (107) with one another, directing a laser beam (108) onto the contact region (107) and forming a welded connection (109), which connects the strip (104) and the layer (103) to one another.
Abstract:
The invention relates to a heating device (10) for a vehicle, comprising: a flow path (14, 16, 20, 22, 24) for a liquid heat transfer agent; an electric heating device (34) for generating heat and for releasing generated heat to the heat transfer agent on a heating portion (20) of the flow path; and an electronic controller (26) for controlling a heat output of the heating device. The controller (26) is provided with a heat releasing body in order to release waste heat of the controller (26) to the heat transfer agent on a preheating portion (16) of the flow path upstream of the heating portion (20). The invention likewise relates to a method for cooling the controller.
