    Abstract: The invention relates to a laser beam welding head for welding metal parts, comprising at least one beam path for a welding beam and means for optically detecting the position of the weld at a first measuring position, wherein the means for optically detecting the position of the weld permit an arrangement of the first measuring position in advance of the welding position of the welding beam in the welding direction and produce a correction signal for correcting the welding position of the welding beam at least as a function of a lateral deviation of the weld from a desired position, and to a corresponding use of the laser beam welding head. In addition, the present invention relates to a method for the beam welding of metal parts, in which the position of the weld is determined at a first measuring position in advance of the welding position of the welding beam using optical detecting means and a correction signal is produced as a function of the deviation of the position of the weld from a desired position. The problem of providing a laser beam welding head and a method for the beam welding of metal parts, with which a very high positioning accuracy and at the same time high welding speeds can be realized, is solved by the distance of the first measuring position (9) in advance of the welding position (8) of the welding beam (2) being selected in such a way that the correction signal produced can be used directly, in particular without preliminary calculation, for activating means (7) for correcting the welding position (8) of the welding beam (2).

    Abstract: The invention relates to a method for welding a first composite metal sheet part (1), which comprises at least two metal layers (2) and a layer (3) arranged between the two metal layers that is made of a material having a different chemical composition than the two metal layers, to a second metal sheet part (1'), which is made of a solid metal material (5) or a further composite material (1') having at least two metal layers (2') and a layer (3') arranged between the metal layers that is made of a material having a different chemical composition than the two metal layers. The aim of providing a method for welding composite metal sheet parts, which comprise at least two metal layers and an intermediate layer arranged between the two metal layers, to a second metal sheet part, which is made of a solid metal material or a further composite material having at least two metal layers and an intermediate layer arranged between the metal layers, by means of which method pore-free welded connections can be produced with high process reliability, is achieved in that the metal sheet parts are welded using a high-frequency welding method.

    Abstract: The invention relates to a method for the inductive high-frequency welding of metal products (1, 2), in which method, with the use of at least one induction conductor (6, 7), the edge regions (11, 12), to be welded, of the metal products (1, 2) are heated by inducing high-frequency currents, the metal products (1, 2) and a welding zone (4) are moved relative to one another, the edge regions (11, 12) to be welded are brought into contact in the welding zone (4) and are welded to one another with a weld (15) being formed. In addition, the invention relates to an apparatus for the inductive high-frequency welding of metal products, comprising means for carrying out a relative movement between the metal products (1, 2) and a welding zone (4) and at least one induction conductor (6, 7) which heats the edge regions (11, 12), to be welded, of the metal products (1, 2) by inducing high-frequency currents. The object, to propose a method of the type in question for inductive high-frequency welding and a corresponding apparatus of the type in question for inductive high-frequency welding, with which method and apparatus metal products (1, 2) having different material thicknesses and/or material grades can be welded to one another in a controlled manner, is achieved in terms of the method by an induction conductor (6, 7) being used which consists of at least two component induction conductors (6, 7) which are separable from one another and which are assigned to the respective metal product (1, 2) and are adapted to the latter, and the heating of the edge regions (11, 12) to be welded is set separately for the respective metal product (1, 2).
