Abstract

Disclosed is a multi-mode laser device for metal manufacturing applications including additive manufacturing (AM), laser cladding, laser welding, laser cutting, laser texturing and laser polishing. The multi-mode laser device configures off-axis, solid-state diode or diode-pumped lasers into an array to perform precision controlled, direct metal deposition printing, cladding, laser welding, laser cutting, laser texturing and laser polishing through a single device. Dual-mode printing, cladding and welding capability using metal wire and powder feedstock sources in the same device is provided with in-line control, precision wire feed driver/controller, adjustable shield gas diffuser, and nozzles tailored to wire feedstock diameter.
