Method and apparatus for distortion control on additively manufactured parts using wire and magnetic pulses

摘要

The invention provides a method and apparatus for forming a freeform metal structure (26) by wire feed additive manufacturing, wherein a metal wire (20) end is moved along an area of deposition (24) and is melted by a heat source (16), the melting being deposited on the metal structure (26) as a metallic build-up material, wherein during the cooling process build-up material is subjected to at least one pulsed magnetic field effecting plastic deformation of the build-up material.
