“…WAAM is a process that when the metal wire (feedstock) is melted by the arc (heat source), it transferred into the melt pool and subsequently solidifies and forms a deposited metal along the planned paths layer by layer as shown in Fig. 2 4,6,8,9,11) . WAAM had been invented in 1925 by the Baker, but it had been studied as AM purpose since 1990s 5,12) .…”

“…And the material efficiency is almost 100 %, so that there is absence of needs for the recycling process of material as does in powder-based AM [4][5][6] . Besides, it can save fabrication time and post-machining time by 40-60 % and 15-20 % rather than the traditional subtractive manufacturing processes, respectively 11,12) . Due to these advantages, WAAM is being a competitive and promising process for decades.…”

“…Mg alloys are the lightest structural metal alloy and has good material properties such as high specific strength, good damping, electromagnetic shielding, machining, recyclability, biodegradability, etc 11,14,[35][36][37] . For this reason, many studies and trials are being conducted in industries of automobile, railway, aviation, aerospace, military, and biomedical 11,36,37) . Most of the parts made of Mg alloys are manufactured by traditional parts making processes such as machining, gravity casting or die-casting 14,[35][36][37][38] .…”

Owing to global trends, automation with the fourth industrial revolution, and environmentally friendly policies owing to certified emission reduction, wire arc additive manufacturing (WAAM) is attracting attention in various industrial fields. In addition, the demands of non-ferrous metals such as aluminum and magnesium alloys are attracting attention from industries that require lightweight, large, and complex metallic parts that can be fabricated through WAAM. In this study, additive manufacturing (AM), WAAM, and current issues on the WAAM of non-ferrous metals particularly aluminum and magnesium alloys are discussed.

“…WAAM uses an electric arc as a heat source and filler wires as raw materials. It is suitable for manufacturing large parts [15][16][17][18][19][20][21] especially for agricultural machinery prone to corrosion and wear after prolonged usage. As a result, wearable parts such as pins need to be replaced frequently, which is not economically feasible.…”

This work describes the wire arc additive manufacturing (WAAM) approach used to fabricate parts from wear-resistant steel. The microstructure, crystal structures, and mechanical properties of the resulting samples were thoroughly analyzed. The wear-resistant steel parts demonstrated good forming, no internal defects, good metallurgical bonding, and excellent wear resistance. The metallographic analysis confirmed that the main phase was ferrite. The microhardness of the sample along its cross section was uniform in both horizontal and vertical directions and equals to 464.7HV0.2 and 482.4 HV0.2, respectively. The average values of tensile strength, elongation ratio, and room temperature Charpy shock were equal to 945.3 MPa, 4.3%, and 5 J, respectively.

Cold metal transfer‐based wire‐arc directed energy deposition offers high molding efficiency and the capability to produce large, complex structural components. However, the grain structure and mechanical performance of the deposited parts are significantly influenced by the thermal history during deposition. This study prepared Inconel 625 samples using two different torch modes (vertical and tilt). The effects of two torch modes and build heights on the molten pool temperature are investigated, and the solidification structure and mechanical performance of the parts at various locations are analyzed. Results show that the deposited samples primarily consisted of columnar dendrites growing epitaxially along the deposition direction, with Laves phase particles distributed in blocks and chains among the dendrites. Tilting the torch contributed to grain refinement and reduced Laves phase precipitates, resulting in samples with high strength. Additionally, the tensile performance of the deposited samples exhibits anisotropy.
