    Powder feed nozzle for laser welding
    WO 2001002129 A3
    Abstract
    A powder feed nozzle (84) for laser welding applications including a multiple outlet nozzle tip (120) for focusing a discharged powder streams. The multiple outlet nozzle tip (120) disperses multiple outlet streams and includes a powder discharge outlet (122) and at least one focus gas discharge outlet (122) and at least one focus gas discharge outlet (124), radially spaced from the powder discharge outlet (122), for dispersing a powder stream and a gas stream. Powder flows from a powder source (128) through a powder channel (126) to discharge a powder stream. Focus gas flows through a focus gas channel (130) angled relative to the powder channel (126) to discharge a focus gas stream.
