Abstract
A device for connecting two components by welding with a laser beam, in which the components are overlapping in a partial region of their mutually facing surfaces. The device includes an optical beam divider that has an inlet for the laser beam and a device for alternately distributing the laser beam to a plurality of outlets. Each of the outlets is optically coupled via a beam-guiding device to a laser welding head which contains a focusing and deflection lens system for guiding the focused laser beam over a surface of a component facing the laser welding head.
