Abstract
A powder feed nozzle for laser welding applications including a multiple outlet nozzle tip for focusing a discharged powder stream. The multiple outlet nozzle tip disperses multiple outlet streams and includes a powder discharge outlet and at least one focus gas discharge outlet, radially spaced from the powder discharge outlet, for dispersing a powder stream and a gas stream. Powder flows from a powder source through a powder channel to discharge a powder stream. Focus gas flows through a focus gas channel angled relative to the powder channel to discharge a focus gas stream.
