Innershield® NR-233

Self-Shielded Flux-Cored Wire

(AWS A5.20-95: E71T-8)

NR-233 is an advanced technology, self-shielded flux-cored electrode designed for high deposition rate welding - even when welding out-of-position in seismic and non-seismic structural steel applications. It is also great for fillet welding for ship and barge fabrication. The elec- trode is welder-friendly, making it easier to pass tough qualification tests and deposit great looking beads. It does all this while delivering Charpy V-Notch properties that meet many of the more stringent codes and specifications for seismic applications.

User Friendly

•For the engineer: meets the stringent codes and standards for Charpy V-Notch properties, such as those listed in FEMA 353.

•For the plant superintendent: higher deposition rates mean faster building erection, quicker launch of the barge, or more throughput in fabrication. In short: less cost and more profit.

•For the welder: a more forgiving arc with greater penetration makes it easier to pass qualification tests, and makes for bet ter quality welds in production — and the welds look great.

•NR-233 has been formulated to minimize gas marking, even after the electrode has been exposed to the atmosphere.

Typical Applications

•Vertical up fillet and groove welds

•Overhead fillet and groove welds

•Seismic structural steel erection

•General structural steel erection

•Barge fabrication
