Problems solved by technology

Unfortunately, LMD processes using powdered materials are not efficient due to the loss of material volume during the blasting process (e.g. deposits cannot enter the molten pool for disposal)
In addition, due to the unconfined nature of powder materials, during the LMD process, there may often be contaminants that end up being deposited with the powder materials

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 atleast 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 ofadditive material on a base material. A method of additively manufacturing or repairing a superalloy component is also presented.

Description

technical field [0001] The present disclosure relates generally to the field of materials technology, and more particularly to additive manufacturing and laser metal deposition processes utilizing fabricated-in-place sintering lines. Background technique [0002] Since superalloys are optimized for high strength (and correspondingly low ductility), there are various technical challenges in welding repair of superalloys. Heat sources such as lasers and electric arcs are applied to build additively manufactured parts or repair damaged superalloy components. One type of process used for additive manufacturing or repair is the laser metal deposition (LMD) process. The LMD process utilizes powdered material deposited into a molten pool to form layers of additive material (also known as buildup). Unfortunately, LMD processes using powdered materials are not efficient because there is a loss of material volume during the blasting process (eg, deposits cannot enter the molten pool...
