Jet nozzle having a powder section and an advance section

Abstract

A jet nozzle for laser cladding along a direction of advance includes a light channel for conducting at least one laser beam directed onto a workpiece, and a powder unit located radially outside the light channel for conducting at least one jet of powder to be applied to the workpiece. The powder unit forms a powder section at a mouth of the jet nozzle in a circumferential direction about the light channel. An advance section that is devoid of the powder unit is contiguous thereto in the circumferential direction.
