The primary process today for robotic arc directed energy deposition (DED), used for large-scale additive manufacturing builds, is gas metal arc welding. However, two other processes, plasma-arc (PA) and gas tungsten arc (GTA) welding, have been recently studied at EWI and shown to offer greater control over power and material inputs during a build.
EWI Project Engineer J. Logan McNeil has written Plasma-arc and Gas Tungsten Arc Directed Energy Deposition Capabilities at EWI to highlight these investigations. You are invited to download this paper – for free – by completing the form on this page.
