Abstract

The invention relates to a nozzle device (100, 200, 300) for generating a powder jet (102, 202, 302) for cladding, in particular laser cladding, comprising a nozzle unit (104, 204, 304) arranged and configured to direct the powder jet (102, 202, 302) onto a processing area (101), and a powder control unit (106, 206, 306) for receiving a powder stream (208, 210, 308, 310) arranged and configured between a powder stream supply (208, 210, 308, 310) to the nozzle unit (104, 204, 304) and a powder stream discharge (208, 210, 308, 310) to a powder stream discharge. (112) to switch, in particular to influence, preferably to reduce and / or prevent and / or increase, the supply of the powder flow (208, 210, 308, 310) to a nozzle outlet (114, 214, 314) of the nozzle unit (104, 204, 304), wherein the powder control unit (106, 206,306) is switchable with a control fluid between the feed and the discharge and / or wherein the powder control unit (106, 206, 306) is designed with the nozzle unit (104, 204, 304).
