An Investigation into Dimensional and Mechanical Properties of Multilayered Metallic Structure Deposited Using TIG Based WAAM Process

Abstract

The wire and Arc Additive Manufacturing process has marked attention due to its higher deposition rates and lower fabrication cost. Many of the researchers have investigated the effect of process parameters of arc-based process like current, wire feeding speed, distance between two adjacent beads i.e. scan spacing on the forming quality and geometry of the deposited thin walled structures. This article gives an impression on the potential of the Wire Arc Additive Manufacturing process to manufacture a fully dense3D metallic structure. The experiments are carried out for the deposition of a fully dense 3D metallic structure with fine dimensional accuracy. A cuboid shaped structure has been successfully deposited by using GTAW based additive manufacturing system. The dimensional accuracy of the cuboid structure deposited by GTAW based additive manufacturing process has been evaluated in this paper. The results showed that the developed process can produce dense metallic structure with enhanced dimensional accuracy and mechanical properties.
