In this study, a modified Accepted 6 March 2010 filler metal that replaces Pd with Ru was evaluated. Initial tests conducted on button-melted samples and Available online xxxx bead-on-plate welds indicated that Ni–Cu–Ru exhibited good corrosion properties. Actual Ni–Cu–Ru arc welds made on SS304L were successfully produced and the corrosion performance was comparable to or Keywords: better than that of Ni–Cu–Pd welds. These welds are a suitable replacement for welds made with stan- A. Ni alloys dard 300-series welding consumables,
