Wire arc hybrid manufacturing

Abstract

A processing head assembly is disclosed. In some examples, the processing head assembly comprises a fabrication energy source; a wire feedstock surrounded by a shield and one or more filler feedstocks surrounded by one or more nozzles. In some examples, the fabrication energy source includes the wire feedstock surrounded by the shield. A method of depositing material on a substrate using a processing head assembly for use with a fabrication energy source; a wire feedstock surrounded by a shield and one or more filler feedstocks surrounded by one or more nozzles is disclosed. In some examples, the method comprises projecting a fabrication energy beam from the fabrication energy source onto the substrate at a spot, projecting the wire feedstock surrounded by the shield onto the substrate at the spot and projecting the one or more filler feedstocks surrounded by the one or more nozzles onto the substrate close to the spot.
