Abstract
Abstract An arrangement and method for establishing an electrical and mechanical connection between electrically conductive members. The arrangement includes an electrically conductive connecting member, two electrically conductive metallic members disposed opposite each other, flanking the connecting member, and clamping the connecting member therebetween, and a source of laser energy oriented such that an output beam therefrom is incident on an outer surface of one of the metallic members and directed towards the underlying connecting member to establish a weld connection at zones of mutual contact between the connecting member and the respective metallic members. The connecting member includes a cable or the like and the metallic members include contact terminals, busbars or the like. In the method, the connecting member is positioned between the metallic members and the output beam is radiated on one of the metallic members in the direction of the connecting member so as to weld the connecting member to the metallic members.
