Verfahren und Vorrichtung zum Schweißverbinden zweier Bauteile

摘要

The invention concerns a device for connecting two components (2, 4) by welding with a laser beam (22), the components overlapping in a partial region of their mutually facing surfaces. According to the invention, the device comprises an optical beam divider (18) which has an inlet for the laser beam (22) and a device (20) for alternately distributing the laser beam (22) to a plurality of outlets (16). Each of the outlets (16) is optically coupled via a beam-guiding device (14) to a laser welding head (12) which contains a focusing and deflection lens system for guiding the focused laser beam (22) over the surface of the component (4) facing the laser welding head (12).
