Testing a laser beam processing device used during laser welding comprises using detectors in predetermined positions so that the laser beam is deviated onto a predefined path with respect to the detectors

摘要

Testing a laser beam processing device comprises using detectors in predetermined positions so that the laser beam is deviated onto a predefined path with respect to the detectors. An independent claim is also included for a device for carrying out the process comprising a unit for aligning and focusing a laser beam, detectors for the laser performance of the laser, and an evaluation unit in contact with the detectors.
