摘要： A process for continuous casting of a metal comprises continuously withdrawing a strand of the metal from a mold along a strand withdrawal direction, measuring the expansion of an inside wall of the mold along the strand withdrawal direction to obtain a component of inside wall expansion in the strand withdrawal direction due to mechanical forces exerted on the inside wall, and controlling the speed of withdrawal based on the component of inside wall expansion in the strand withdrawal direction due to mechanical forces. If the component of inside wall expansion of in the strand withdrawal direction due to mechanical forces exceeds certain limit values, the withdrawal step is slowed or interrupted, thereby eliminating break-outs due to cobbles. In an embodiment of the invention, expansion measurements are also taken along a direction transverse to the withdrawal direction, enabling the elimination of the component of expansion in the withdrawal direction due to heat.

摘要： A process for the butt-welding of especially deep-drawable steel sheets or steel strips galvanized at least on one side, in which the welding seam is protected against corrosion. To obtain a welding seam flush with the sheet and protected against corrosion, without the reworking of the welding seam and without the use of filler material, sheets or strips having essentially rectangular cut edges with a corrosion in the longitudinal direction of at most 0.4 mm are used. The sheets and strips brought into touch contact with these cut edges are melted in the region of the welding joint by means of a laser beam, of which the focal spot covering the cut edges has a diameter of at most 0.2 mm. Because of the extremely narrow welding gap, the voids are filled by the molten material of the adjacent sheets, without any detectable reduction in the thickness of the sheets or strips. Furthermore, the welding seam is protected against corrosion as a result of the long-range protection effect exerted by the zinc of the adjacent regions.

摘要： The invention relates to a light structural steel plate in the form of a hump plate and to a process for its production. The light structural steel plate comprises a mould-pressed steel hump plate (1) and a flat aluminium plate (3) connected thereto substance-to-substance at a the hump end faces. The substance-to-substance connection is produced by the feature that after the surfaces to be interconnected at the hump end faces have been activated by means of a laser beam (5), said surfaces are metallically connected under pressure. The decisive factor is that the material of the plates (1, 2) does not pass into the molten phase during activation by means of the laser beam (5).
