This research paper explores wire arc additive manufacturing (WAAM), a production method utilized to 3D print or repair metal objects, specifically focusing on Inconel 625 (I-625), a nickel superalloy. The objective of this study is to analyze the mechanical and microstructural changes that occur during the fabrication of I-625 alloy using Cold Metal Transfer-WAAM (CMT-WAAM). Employing a thorough methodology that includes microstructural examinations and mechanical property assessments, the research reveals variations in microstructure throughout the layers of the manufactured specimens, with an increase in travel speed correlating with enhanced microhardness from 255 HV to 259 HV. Results indicate a notable improvement in yield strength from 650 MPa to 690 MPa and ultimate tensile strength from 380 MPa to 408 MPa. While the mechanical performance of the manufactured components outperformed that of casting parts, an exception was noted in ultimate tensile strength. This study substantiates the potential for producing high-quality I-625 alloy components through the CMT-WAAM technique.
