More Information
Summary:Device for laser powder coating the inner surface (16) of a component with an especially powdered additional material comprises a laser source (1) optically connected to a device head (3), and a coating lance (4) in which the laser beam is axially directed by a rotating guide (5) toward the lance tip and then toward the inner surface of the component. The coating lance contains a light guide (2) extending from the rotating guide toward the lance tip and guiding the laser beam. Preferred Features: The laser source is a diode laser.
