| Abstract: | A novel multi wire feed mechanism has been introduced and investigated for tungsten-inert-gas-based wire arc additive manufacturing (WAAM-TIG) method to minimise the dependency of wire feed direction. The concurrent three wire feed mechanism mounted 120° apart around the TIG torch was developed by employing three independent wire feeders, and an integrated effect of front-back-side feeding minimised the dependency of the wire feeding direction on the deposited bead. The mechanism was compared with the single wire feed, and geometrical uniformity, material deposition rate and overall specific energy requirements were found to improve by ∼26%, ∼66% and ∼56%, respectively, with good arc-stability. © 2024 Elsevier Ltd |
