Arcos Industries LLC (www.arcos.us) has introduced two bare wires for corrosion resistance in specific welding applications.

Arcos 816 (ERNiCu-7) is an electrode designed for welding nickel-copper alloys (ASTM B127, B163, B164 and B165). Dissimilar welding applications include joining nickel-copper and copper-nickel alloys to Nickel 200. The wire is designed for welding in salt, seawater and reducing acids environments.

Arcos 72 (ERNiCr-4) is for GTAW/GMAW overlay of nickel-chromium alloy onto carbon and stainless steel and for cast repair. Due to its resistance to high temperature and fuel-ash corrosion, Arcos 72 is targeted at the overlaying of carbon steels to provide a nickel-chromium alloy corrosion surface in high-temperature sulfur and vanadium atmospheres.
