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.
