Abstract

The invention relates to a nozzle consisting of a metallic material for a device for electron-beam welding, said nozzle (34) comprising a rear or base body (70) to which a nozzle head (36) is joined by means of a tubular nozzle connecting piece (56). The invention is characterised in that the nozzle head (36) and the base body (70) are formed from a copper alloy and are screwed together. In a preferred mode of embodiment, the axial nozzle connecting piece (56) is provided with an outer thread (62) and can be screwed into an axial inner thread (76) of the base body (70). Furthermore, the inner thread (76) of the base body (70) is preferably arranged in a cylindrical base recess (74) of the base body (70).
