摘要： The invention relates to a method for laser welding one or more workpieces made of press-hardening steel, in particular manganese-boron steel, in a butt joint, wherein the workpiece or the workpieces (1, 2) have a thickness between 0.5 and 1.8 mm and/or a thickness jump (d) between 0.2 and 0.4 mm arises at the butt joint (3) and wherein, during the laser welding, filler wire (10) is fed into the molten pool (8) produced by means of at least one laser beam (6), wherein the molten pool (8) is produced exclusively by the at least one laser beam (6). According to the invention, in order to ensure that the weld can be reliably hardened into a martensitic microstructure during the hot forming (press hardening), the filler wire (10) contains at least one alloying element from the group comprising manganese, chromium, molybdenum, silicon, and/or nickel, which alloying element promotes the formation of austenite in the molten pool (8) produced by means of the laser beam (6), wherein said at least one alloying element is present in the filler wire (10) at a mass fraction that is greater than the mass fraction of the at least one alloying element in the press-hardening steel of the workpiece or the workpieces (1, 2) by at least 0.1 wt%, and wherein the workpiece used or the workpieces (1, 2; 1, 2') used are non-coated or the coating thereof is partially removed.

摘要： The invention relates to a method for producing a tailored hot-formable semifinished sheet metal product. At least two steel sheets (1, 2') with different degrees of material quality and/or thickness are joined together by a butt joint by means of laser welding. At least one of the sheets is made of a press-hardened steel and has an aluminum- or aluminum-silicon-based metal coating (1.1, 2.1). According to the invention, the steel sheets (1, 2') are welded to each other with a gap (G) which is delimited by the sheet borders to be welded together and which has an average width (b) of at least 0.15 mm. Filler wire (8) material is introduced into the gap (G) to such a degree that the proportion of the filler wire volume introduced into the gap (G) to the volume of the steel sheet material melted by the laser beam is at least 20%. The method according to the invention does not require the coating to be removed from the edges of the sheet borders to be welded together in advance and thus offers substantial cost advantages.

摘要： The invention relates to a method and a device for butt welding coated sheet metals (1). In the method according to the invention, at least one powder welding additive (8) in the form of a gas-powder flow (9) is fed to the welding melt (6) via at least one flow channel (10) in such a manner that the gas-powder flow (9) exiting the flow channel (10) is directed at the welding melt (6) and has an exit speed of at least 2 m/s such that the welding additive (8) and the welding melt (6) are turbulently mixed, wherein flow eddies (12) are formed in the welding melt. The device according to the invention comprises at least one welding head for generating and/or focusing an energy beam (3) for fusion-welding sheet metal material and at least one flow channel (10) for feeding a powder welding additive (8) in the form of a gas-powder flow (9), a longitudinal axis of the channel portion (10) and a beam axis of the energy beam (3) forming an angle that ranges from 15 degrees to 75 degrees.
