    摘要: 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.

    摘要: A method includes producing sheet steel products, in which steel blanks or steel strips of different thicknesses and/or material grades are welded together along a joint formed by edges of the steel blanks or steel strips. In order that the welding seam of such a sheet steel product does not lose the hardened microstructure obtained by abrupt cooling during warm forming with heating to an austenization temperature, before the welding process, a viscous liquid, such as a paste, or a solid, pulverulent, or aerosol-like substance that contains at least one component that increases the strength of the weld seam that is to be produced, is applied to at least one weld edge of the steel blanks or steel strips that are to be welded together.
