Abstract:
1. Laser beam welding head for the welding of metal parts with at least one beam path for a welding beam and means for optical acquisition of a position of the welding seam at a first measuring position, wherein the means for the optical acquisition of the position of the welding seam allow arrangement of the first measuring position at least in a welding direction running ahead of the welding position of the welding beam and, at least as a function of a lateral deviation of the welding seam from a reference position, generate a correction signal for the correction of the welding position of the welding beam, wherein a distance interval from the first measuring position running ahead to the welding position of the welding beam is selected in such a way that the correction signal generated is used directly without considering the leader length of the first measuring position and without an advance run calculation to actuate means for correcting the welding position of the welding beam, the laser beam welding head including at least one actuator element is provided in the at least one beam path of the welding beam in order to change the welding beam position, which can be actuated by the correction signal, wherein, as the actuator element, at least one tiltable mirror is provided.
