Description
Summary:Wire Arc Additive Manufacturing (WAAM) is the process of used to fabricate material samples by deposition of material which is in wire form at high temperature ER-4043 Aluminium wire is deposited on substrate steel plate and predicted the properties by following Taguchi orthogonal Array. It reduces the complexity occurs by conventional process in fabricating a large size, complex shape components. In the present investigation, the optimized multi-responses by Orthogonal Array (OA) which are strength and hardness values obtained during WAAM process for nine samples are evaluated to presage the influence of process parameters through Grey Relational Analysis (GRA) followed by Taguchi method.
