Zirconium 702 Welding Wire UNS R60702 Wire for Pressure Vessel

Description

Zirconium 702 welding wire is a high-performance wire designed for joining zirconium alloys, especially Zirconium 705, in applications requiring excellent corrosion resistance, thermal stability, and mechanical strength.

It is available in standard diameters ranging from 0.045" to 0.125", and supports multiple welding processes such as:

Gas Tungsten Arc Welding (GTAW / TIG)

Gas Metal Arc Welding (GMAW / MIG)

Shielded Metal Arc Welding (SMAW)

Zr702 wire, primarily composed of zirconium with minor alloying elements, provides reliable weld integrity in corrosive and high-temperature environments such as chemical plants, heat exchangers, and nuclear facilities.
