Abstract
A laser beam welding head for the welding of metal parts and method of use include at least one beam path for a welding beam and means for the optical acquisition of the 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 in the 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, as well as a corresponding use of the laser beam welding head.
