A method for producing a screw connection, a device for machining a workpiece, in particular for thermal piercing, screw, as well as the use of a screw

摘要

in a method for the manufacture of a schraubverbindung, in which a workpiece is a breakthrough and a trained gewindeformende screw in the breakthrough eingeschraubt is erfindungsgemu00e4u00df provided that the breakthrough through an arc, electron beam or egg a laser beam is trained.a further training envisages that the screw (38, 40) during the training of the breakthrough as a welding electrode is used.a device for machining a workpiece (2), in particular for thermal lochstechen, with a cutting torch (4), which is an arc, an electron beam or a laser beam to the influence on the workpiece (2), which is erfindungsgemu00e4u00df provided that the cutting torch (4) at least two mutually separable parts infrom a position forming a space (34) in a rest position auseinanderfahrbar, so that in the rest position, a custom tool for further processing of the workpiece (2) through the space (34) movements, and the back in position. menfahrbar.
