Solid MIG (GMAW) wire feeds continuously through the gun, which keeps the arc stable and lets the operator focus on travel and angle. Wire chemistry must match the base metal, and shielding gas must match the wire type, per AWS A5 classifications.
Lincoln Innershield NR-311 Ni inch FCAW-S Welding Wire is designed to provide a nominal 1.5% nickel weld deposit with high deposition rates and fast travel. Recommended for flat and horizontal positions in single and multiple pass welding.
- Designed to provide a nominal 1.5% nickel weld deposit
- High deposition rates and fast travel speeds
- Capable of producing weld deposits with impact properties exceeding 27 J (20 ft·lbf) at -29°C (-20°F)
- Color match on weathering steel applications
- 3/32 in (2.4 mm) diameter meets FEMA 353 and AWS D1.8 seismic lot waiver requirements
- FEMA 353 and AWS D1.8 structural steel seismic supplement test data can be found at the Lincoln Electric Certificate Center
