dc.description.abstractWire arc additive manufacturing (WAAM) has recently gained great attention in producing metallic parts due to significant cost savings, high deposition, and its convenience. However, there is still limited knowledge concerning testing for mechanical properties of the WAAM-produced steel parts using different welding wires. This paper presents the results of the extensive experimental study aimed at assessing the mechanical properties of the WAAM-produced multi-pass thick-walled steel parts using two different ER70S-6 and one ER110S-G welding wires. This study focused on revealing the role of the microstructure on the fracture toughness values, which were obtained from the specimens extracted in two directions, namely, transversal direction (T) and longitudinal direction (L) according to the deposition direction. Before extraction of the toughness specimens, the computed radiography (CR) tests were performed to detect if any welding defects occurred during the layer deposition. Next, the microstructural features of the thick-walled WAAM parts were characterized by stereo microscopy (SM), optical microscopy (OM), and scanning electron microscopy (SEM). Finally, the mechanical properties of the part were evaluated by Charpy V-notch (CVN) impact toughness, tensile, and hardness tests. The results exhibit an anisotropic material behavior in as-built conditions for each filler metal. Therefore, careful consideration of notch orientations and their effects on mechanical properties is important in assessing the fitness-for-service performance of the WAAM-produced low-alloyed steel parts.en_US
