 Effect of Shielding Gas on parts manufactured by WAAM. Wire arc additive manufacturing (WAAM) is a fusion manufacturing process in which the heat energy of an electric arc is employed for melting the electrodes and depositing material layers for wall formation or for simultaneously cladding two materials in order to form a composite structure. Effect of shielding gas  Argon  Low arc temperature and low thermal conductivity  Nitrogen  Free burning arcs are unstable N2 being a diatomic molecule, first will dissociate into its atoms and only then ionize. So the formation of the ionization column is harder in N2     ACM (80% Ar + 20% CO2)   The best shielding gas compared to the above gases References: Chaturvedi, M.; Scutelnicu, E.; Rusu, C.C.; Mistodie, L.R.; Mihailescu, D.; Subbiah, A.V.
