Abstract: An assembly includes a workpiece and a fastening element. The fastening element is configured to drill a hole in the workpiece and allow the fastening element to be friction-welded to the workpiece.

Abstract: A fastening element for friction welding onto a planar workpiece includes a nut head, a through-bore extending at least locally within the nut head, a friction welding face on one end side of the nut head, and a cutting device for introducing a drilled hole into the workpiece on the one end side of the nut head having the friction welding face.

Abstract: A hot-forming line for producing hot-formed and press-quenched sheet-steel products includes a temperature control station for heating at least one sheet-metal blank, a hot-forming and press-quenching tool for hot forming and press quenching the heated sheet-metal blank and at least one blank gripper for gripping and transferring the sheet-metal blank before and/or after hot forming and press quenching. The at least one blank gripper forms at least one contact region with the sheet-metal blank during the gripping of the sheet-metal blank. Also, the at least one blank gripper is configured to cool the sheet-metal blank in the at least one contact region during gripping and transfer of the sheet-metal blank before hot forming and press quenching and/or heat the sheet-metal blank in the at least one contact region during gripping and transfer after hot forming and press quenching.

Abstract: A production method for manufacturing a hairpin coil includes positioning a plurality of hairpin-like conductor elements on a coil support such that conductor end portions of conductor elements to be connected, which protrude from the coil support, are arranged adjacent to one another as conductor end portion pairs, securing the relative position of the conductor end portions of a conductor end portion pair, and simultaneously welding the respective conductor end portions of a plurality of conductor end portion pairs by friction welding, by a friction surface of a welding tool being simultaneously moved in a frictional manner along the plurality of conductor end portion pairs.

Abstract: A method of manufacturing a tool part of a forming tool. The method includes forming a tool element of the tool part having a shape-imparting operating face and at least one first cooling duct for cooling a liquid using an additive manufacturing machine. The first cooling duct has at least one rectifier portion including a blocking direction and an opposing passing direction. The blocking direction has a higher flow resistance to cooling liquid than the passing direction.
