Laser processing apparatus for welding e.g. workpiece, has mirror that is arranged rotatably in working optical path so that focal position of laser beam is displaced into interaction zone transversely to optical axis of focusing lens

摘要

The apparatus has a pressure roller (11) that is attached to the support (14) so as to bias the to-be-processed components (9) during the machining. The working optical path for the laser beam (18) is led through housing of laser machining head (10). A focusing optical system is arranged to focus laser beam in an interaction zone (19) between laser beam and to-be- processed components. A mirror is arranged rotatably in the working optical path so that the focal position of the laser beam is displaced into the interaction zone transversely to the optical axis of the focusing lens.
