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.
期刊介绍：
The CIRP Journal of Manufacturing Science and Technology (CIRP-JMST) publishes fundamental papers on manufacturing processes, production equipment and automation, product design, manufacturing systems and production organisations up to the level of the production networks, including all the related technical, human and economic factors. Preference is given to contributions describing research results whose feasibility has been demonstrated either in a laboratory or in the industrial praxis. Case studies and review papers on specific issues in manufacturing science and technology are equally encouraged.
