ABSTRACT:
A method of cladding a wire with a powdered metal includes feeding the wire in its axial direction, applying powdered metal around its surface, compacting the applied powdered layer on the surface and subsequently continuously rolling-over the applied layer on a helical path to provide a helical zone of metallurgically bonded powdered material. The device of this invention has a storage container for powdered material, a rotary shaft defining at its center a forwardly tapering passage with an internal thread acting as a worm conveyor, the shaft being terminated with an exchangeable outlet nozzle, the nozzle supporting a set of cladding rollers, the axes of rotation of which are inclined at an acute angle to the axis of the passage. The driving arrangement for the rollers is preferably driven by a separate motor.
