This work explored the possibility of producing a compositional functionally graded material (FGM) between mild steel and Inconel 625. An in-house fabricated, dual filler wire tungsten inert gas welding set up was used to deposit weld beads on a mild steel substrate. Filler wire feed rates were controlled independently and the combinations of filler material volumes, i.e., mild steel–Inconel 625 of (100:0), (75:25), (50:50), (25:75), and (0:100) were fed into the arc simultaneously and individual weld beads deposited. Preliminary studies revealed that defect free completely fused new alloys were formed and intermetallic phases rich in Nb observed. Compositional analysis showed that the content of each element changed from one alloy to the other gradually, smoothly indicating the feasibility of a mild steel–Inconel 625 functionally graded material.
