Özet
Additive manufacturing (AM) has gained prominence in the industrial sector due to its superior capability for fabricating small parts and meeting larger requirements in many fields. Among the AM processes, wire arc additive manufacturing (WAAM), which is commonly based on the welding process, is also a good option for manufacturing large-scale metallic components. In the present study, WAAM was performed using gas metal arc welding (GMAW). In addition, two customized 3D printers having different types of welding torch movements were used in the deposition process. Because it is generally preferred for joining works in the welding process, ER70S-6 filler wire was chosen for the WAAM. Two different parts were fabricated using this filler wire. The effects of the different torch movements on the properties of the WAAM samples were investigated via tensile and microhardness tests and microstructural examinations were performed. Moreover, the specimens were processed from three different material directions (horizontal, vertical, and 45 degrees) in order to observe the layer effects. Following the WAAM process, optical emission spectrometry (OES) studies were conducted to evaluate the chemical composition of the parts. Visual inspection was then carried out to assess the layer features of the fabricated WAAM parts.
