Title (EN) LASER METAL DEPOSITION HEAD
(FR) TÊTE DE DÉPÔT DE MÉTAL AU LASER
Abstract:
(EN) 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.
(FR) Des aspects de la présente invention concernent des têtes améliorées de dépôt de métal au laser. Divers modes de réalisation peuvent comprendre un corps principal, un siège de buse, un guide d'écoulement de poudre, une buse interne, une buse externe et un manchon de fluide de refroidissement. Dans certains modes de réalisation, des entrées de poudre dans le corps principal sont inclinées par rapport à un axe principal de la tête de dépôt de métal au laser. Dans certains modes de réalisation, le siège de buse comprend une pluralité de canaux de distribution de poudre qui sont également inclinés par rapport à l'axe principal de la tête de dépôt de métal au laser.
