Abstract. Wire Arc Additive Manufacturing (WAAM) represents a revolutionary advancement in 3D metal printing, enabling efficient and cost-effective production of large-scale, complex metal components. This technology leverages Gas Tungsten Arc (GTA) and Gas Metal Arc (GMA) welding processes, making it suitable for a wide range of metals, including stainless steels, aluminium alloys, and titanium alloys. The WAAM process involves a layer-by-layer deposition of molten metal, utilizing an electric arc to melt wire feedstock. Despite its advantages, WAAM faces challenges related to thermal cycles and microstructural inconsistencies, which can impact the strength and ductility of the final components. Recent research has focused on the microstructural analysis and mechanical properties of WAAM-fabricated components. Studies have demonstrated that distinct heat cycles during the WAAM process led to various microstructures, such as bainitic lamellae, ferrite grains, and pearlite strips. For instance, Liberini et al. (2017) found unhomogenized microstructural formations in their study on 316L austenitic stainless steel. Additionally, Vickers microhardness evaluations have shown that WAAM components exhibit consistent hardness across different zones, with variations depending on the microstructural constituents. Optimizing WAAM processes requires a thorough understanding of these microstructural characteristics and the influence of welding parameters. By adjusting process parameters and employing advanced welding techniques, researchers aim to enhance the mechanical properties and reliability of WAAM-fabricated components. The ongoing advancements in WAAM technology and research underscore its potential for diverse industrial applications, promising significant improvements in efficiency, cost-effectiveness, and the overall quality of large-scale metal manufacturing.
