摘要： The invention relates to a flat product made of metal material, in particular a steel material, an advantageous use and a roll particularly suitable for producing such a flat product, and a method for producing such flat products. In order that the flat product, in particular thin metal sheet, exhibits improved tribological properties and provides very good preconditions for a paint coating, which also has an excellent appearance even in the case of a lower overall layer thickness of the paint structure in the finally painted state, it has been provided with a deterministic surface structure which has multiple depressions which have a depth in the range from 2 to 14 μm, wherein the depressions are designed to be I-shaped, H-shaped, cross-shaped, C-shaped or X-shaped, and wherein the surface structure is characterized by a peak index RPc in the range from 45 to 180 1/cm, an arithmetic mean roughness Ra in the range from 0.3 to 3.6 µm, and an arithmetic mean waviness Wsa in the range from 0.05 to 0.5 µm. A roll according to the invention which is particularly suitable for producing such a flat product has been textured by means of a short-pulse laser process and has a deterministic surface structure which has multiple overlapping cells which are arranged in such a way that they delimit double-I-shaped, H-shaped, cross-shaped, C-shaped or X-shaped material structures in the roll surface, and wherein the surface structure of the roll, measured in the roll axial direction, is characterized by a peak index RPc in the range from 80 to 180 1/cm, an arithmetic mean roughness Ra in the range from 2.5 to 3.5 µm, and an arithmetic mean waviness Wsa in the range from 0.08 to 1.0 µm.

摘要： 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).

摘要： The invention relates to a method for machining a workpiece (10), in particular a component of a motor vehicle, by means of a laser beam, wherein a laser beam (1) is applied to the workpiece (5) by means of a scanner (5), material of the workpiece is ablated, the radiation created by the plasma (8) during the process in the work area and/or the reflected laser radiation is detected and a signal is generated in accordance with the detected plasma and/or laser radiation. The aim of providing a method by means of which greater process reliability can be assured during laser beam machining is achieved by controlling, by closed-loop or open-loop control, the position of the laser beam in relation to the workpiece and/or the ablation depth in accordance with the signal.

摘要： The invention provides a bipolar plate for a fuel cell (2) which can be produced in a particularly cost-effective manner, in the case of which high efficiency is ensured over a long use period. For this purpose, the bipolar plate has a core layer consisting of a steel material, the surfaces of said core layer which are associated with the respective electrolyte carrier of the fuel cell each being provided with an anti-corrosion layer protecting the core layer from corrosion. According to the invention, in this case the anti-corrosion layers are each made from a metal material and extend on both sides in each case completely over the core layer (10). At the same time, the anti-corrosion layers (11, 12) for their part are each completely covered by an electrically conductive functional layer (13, 14), which is substantially completely impermeable to metal ions emerging from the core layer (10) and/or the anti-corrosion layers (11, 12). The invention likewise relates to a fuel cell comprising at least one bipolar plate according to the invention.
