“…Among steels, stainless steels have found applications in chemical plants and nuclear industries, where parts with high heat and corrosion resistance are required (e.g., pressure vessels). Austenitic stainless steel, such as SS 304 [68], SS 308LSi [69], and SS 316L [70,71] have been successfully used in WAAM, as well as martensitic stainless steel 420 [72].…”

“…Apart from the already referred alloys, other metals have been studied, such as copper-aluminum (Cu-Al8Ni2Fe2) [70], a dissimilar deposition of stainless steel and Ni-based alloy [99], and lastly, NiAl bronze alloys (NAB) with potential for marine applications [8,100]. Aluminum-copper (ER2319) and aluminum-magnesium (ER5087) were fed into the same electric arc, and by adjusting the wire feed speed different chemical combinations were achieved (Al-3.6Cu-2.2Mg, Al-4Cu-1.8Mg, and Al-4.4Cu-1.5Mg) [93].…”

Additive manufacturing has revolutionized the manufacturing paradigm in recent years due to the possibility of creating complex shaped three-dimensional parts which can be difficult or impossible to obtain by conventional manufacturing processes. Among the different additive manufacturing techniques, wire and arc additive manufacturing (WAAM) is suitable to produce large metallic parts owing to the high deposition rates achieved, which are significantly larger than powder-bed techniques, for example. The interest in WAAM is steadily increasing, and consequently, significant research efforts are underway. This review paper aims to provide an overview of the most significant achievements in WAAM, highlighting process developments and variants to control the microstructure, mechanical properties, and defect generation in the as-built parts; the most relevant engineering materials used; the main deposition strategies adopted to minimize residual stresses and the effect of post-processing heat treatments to improve the mechanical properties of the parts. An important aspect that still hinders this technology is certification and nondestructive testing of the parts, and this is discussed. Finally, a general perspective of future advancements is presented.

“…TC18 is of the most widely used titanium alloy in aircraft applications for high structural strength. A TC18 cubic block with a size of 55 mm is manufactured by laser AM, the detailed description of the manufacturing process can be found elsewhere [18]. Three artificial flaws, in terms of flat deep bottom holes with a depth of 5 mm and a diameter of 0.8 mm, are created on three adjacent surfaces of the specimen by drilling, as shown in figure 2(a) and also schematically illustrated in figure 2(b).…”

While titanium components manufactured by additive manufacturing have been widely used in direct molding of complex components, their performance is strongly affected by existing internal flaws generated in the unique manufacturing process. Thus, how to efficiently and accurately characterize geometrical characteristics of internal flaws is critical for enhancing applications of additive manufactured titanium components. In the present work, an effective non-destructive method by using phased array ultrasonic testing is proposed to characterize sub-millimeter artificial deep bottom holes in additive manufactured TC18 titanium block. Specifically, a phased array ultrasonic testing platform integrated with total focusing method-based post-processing algorithm is established. Flat bottom holes with a diameter of 0.8 mm and a depth of 5.0 mm in 55 mm-sized cube titanium block are detected using both linear and annular array transducers. Experimental results show that preexisting holes can be characterized by both linear and annular transducers, in despite of accompanied high acoustic attenuation. Furthermore, the annular phased array ultrasonic testing has higher detection accuracy and resolution than the linear phased array one, for its stronger capability of sound field focusing. More importantly, the annular phased array ultrasonic testing shows similar high testing accuracy in different relative orientations between forming orientation of the titanium component and sound wave propagation direction. These findings provide an effective strategy for the non-destructive ultrasonic testing of titanium components by additive manufacturing.

“…Previous studies on WAAM of stainless steel report the use of Gas Tungsten Arc Welding (TIG) for 308LSi steel, Cold Metal Transfer (CMT) for 240 steel [4], CMT and automated TIG welding (Top TIG) for stainless steel with the aim of optimizing deposition rate [5] and deposition strategies for any material [6]. An attempt to reach high productivity has been reported by Yuehai Feng [7] using double wire plasma arc in comparison with single wire with good results Queguineur, A. et al analyse the potential of additive manufacturing for large components using the CMT process and the consequences on the manufacturing time for austenitic stainless steel parts used in naval construction [8].…”

This study investigates the feasibility of achieving high deposition rate using wire + arc additive manufacturing in stainless steel to reduce lead time and cost of manufacturing. The pulse MIG welding technique with a tandem torch was used for depositing martensitic stainless steel 17-4 PH. The mechanical and metallurgical properties of the manufactured component were analysed to evaluate the limitations and the extent to which the rate of deposition reaches a maximum without any failure or defect being evident in the manufactured component. Deposition rate of 9.5 kg/hr was achieved. The hardness was matched for the as deposited condition.
