Powder feed cylinder assemblies and powder feeders are provided. A powder feed cylinder assembly includes a cylinder, a bit, and bushings. The cylinder has a main passage, a first feed channel, and a second feed channel, each feed channel at two axial locations between the cylinder's two ends. The bit extends through the main passage and has an outer surface including a helical channel formed thereon. A center bushing is disposed in the main passage between the two axial locations and has a first axially-extending passage through which the bit extends. The first end bushing is disposed in the main passage on one side of the center bushing and has a second axially-extending passage through which the bit extends. The second end bushing is disposed in the cylinder on the other side of the center bushing and has a third axially-extending passage through which the bit extends.

A novel and inventive hand held powder-fed laser fusion welding torch providing manual flexibility for laser welding with powder-fed material. The hand held laser includes a body, handle, and nozzle assembly. The nozzle may be shrouded by a cover that is slightly spaced apart from the nozzle. The gap between the two may provide space through which inert gas may flow. Laser light from a remote source shines through the nozzle's central aperture. The nozzle aperture may be circumscribed by powder channel outlets aligned upon a working focal point coincident with the laser beam to treat a workpiece. A proximity sensor may enable selective welding torch operation according to the presence of a workpiece.
