Innershield® NR-203 Nickel (1%) Flux-Cored FCAW-S Welding Wire, 5/64 inches is designed to produce a nickel bearing weld deposit with impact properties capable of exceeding 27 J (20 ft·lbf) at -29°C (-20°F). It handles poor fit-up in the vertical up position and welds gaps up to 9.5 mm (3/8 in).
- Designed to produce a nickel bearing weld deposit with enhanced mechanical properties
- Capable of producing weld deposits with impact toughness exceeding 27 J (20 ft·lbf) at -29°C (-20°F) for low-temperature service
- Color match on weathering steels for aesthetic consistency
- Handles poor fit-up conditions and welds gaps up to 9.5 mm (3/8 in) with excellent gap-bridging capability
- Root bead capability for open root welding applications
Typical Applications
- Roundabout groove welds on heavy wall tubular construction
- Offshore structural fabrication and marine applications
- Bridges and other structural components made from weathering steels (ASTM A588, A606, A847)
- Structural fabrication requiring low-temperature impact toughness
- NACE applications and corrosive environments
