Abstract
Aspects of the present disclosure relate to improved laser metal deposition heads. Various embodiments may include a main body, a nozzle seat, a powder flow guide, an inner nozzle, an outer nozzle, and a coolant sleeve. In some embodiments, powder inlets in the main body are angled relative to a primary axis of the laser metal deposition head. In some embodiments, the nozzle seat includes a plurality of powder distribution channels that are also angled relative to the primary axis of the laser metal deposition head.
