Lincoln Innershield® NR-305 3/32 inch self-shielded flux-cored welding wire is designed for in-position, high deposition welding on carbon steel. Recommended for single or multiple pass, automatic and semiautomatic welding applications requiring maximum productivity.
Features
- High deposition rates in the flat and horizontal positions maximize productivity and reduce welding time
- Smooth arc performance and low spatter levels for clean, high-quality welds
- Capable of producing weld deposits with impact properties exceeding 27 J (20 ft·lbf) at -29°C (-20°F) for low-temperature service
- Welds effectively on lightly rusted or primed plate without extensive surface preparation
- AWS D1.8 structural steel seismic supplement test data available in the Lincoln Electric Certificate Center
Typical Applications
- General plate fabrication and heavy structural assembly
- Structural fabrication, including buildings and structures subject to seismic requirements
- Shipyards and marine applications - stiffener welding on barges and vessels
- Bridge construction and offshore rig fabrication
- Welding over tack welds made with stick electrode
Welding Positions
- Flat and Horizontal positions only
Shielding Gas
- Self-shielded - No external shielding gas required
