Abstract

A method of forming an additively manufactured aluminum part includes establishing an arc between a metal-cored aluminum wire and the additively manufactured aluminum part, wherein the metal-cored aluminum wire includes a metallic sheath and a granular core disposed within the metallic sheath. The method includes melting a portion of the metal-cored aluminum wire using the heat of the arc to form molten droplets. The method includes transferring the molten droplets to the additively manufactured aluminum part under an inert gas flow, and solidifying the molten droplets under the inert gas flow to form deposits of the additively manufactured aluminum part.
