Functionally graded materials (FGM) are structures that can provide different material properties together. To produce these structures, the additive manufacturing method has been used and preferred. In this study, an FGM structure was fabricated by wire arc additive manufacturing (WAAM) process using low-alloy ER70S-6 and austenitic stainless steel 308LSi metal wires. The FGM structure was characterized by tensile, fatigue, hardness tests, and microstructure examinations. As a result of the applied tests, it was found that the FGM structure has strong interfacial strength. In addition, no formations or defects that could reduce the strength of the FGM part were observed at the interface and in the regions close to the interface. The sides of the FGM part containing the base material could reflect their characteristic material properties. FGM part, whose properties can be changed partially, has been successfully fabricated.
