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.

• 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.
