Abstract: A system for manufacturing of a sintered wire and in-situ feeding to a laser wire welding system is presented. The system includes a pressure vessel connected to a powder feed system for delivering at least two powders to a powder mixing zone of the pressure vessel. The at least two powders are mixed via a rotating cone in the pressure vessel. After mixing, a heating device contained within the pressure vessel heats the mixture so that liquid phase sintering occurs and a sintered rod is created. The sintered wire is continuously fed to a laser metal deposition system for depositing a layer of additive material on a base material. A method of additively manufacturing or repairing a superalloy component is also presented.
