| Abstract Scope |
This study explores the capabilities of an in-house developed multi-wire Wire Arc Additive Manufacturing (M-WAAM) system based on Gas Tungsten Arc Welding (GTAW). The setup features four wire feeding nozzles that enable the simultaneous deposition of multiple filler wires, utilizing two Mild Steel ER70S-6 wires and two SS-316L wires. This innovative approach allows precise control over phase composition by adjusting the wire feed rates of the filler wires, facilitating the development of customized alloys tailored to specific applications. The metallurgical and mechanical analyses, including microstructural evaluations, tensile testing, and microhardness assessments, highlights the system’s capabilities. The results reveal significant enhancements in ultimate tensile strength and tailored hardness values, which are directly correlated to variations in the wire feed rates of the ER70S-6 and SS-316L wires. These findings demonstrate the potential of M-WAAM to produce advanced materials with superior mechanical properties, emphasizing its adaptability and effectiveness in meeting rigorous performance requirements. |
