Abstract:
An apparatus for welding together with a laser beam two components which overlap in a subregion of their mutually facing surfaces, comprising:a stationary laser source outputting a laser beam;a plurality of movable laser welding heads;a plurality of beam-guiding devices;an optical beam distributor having an input for receiving the laser beam, a plurality of outputs each coupled optically to a respective one of said plurality of laser welding heads via a respective one of said plurality of beam-guiding devices, and a distributor for alternately distributing the laser beam between said plurality of outputs; anda plurality of focussing optical systems and a plurality of deflecting optical systems, one of said focussing optical systems and one of said deflecting optical systems being disposed in a respective one of said plurality of laser welding heads receiving, guiding, and focussing the laser beam over a surface of a component facing a respective one of said laser welding heads,whereby at least one of said focussing optical systems and said deflecting optical systems is moveably disposed within a respective at least one of said laser welding heads for guiding the laser beam over the surface of the component when said respective at least one of said laser welding heads is in a fixed position.
