The most common FCAW structural steel wire is?

• A. NR 112
• B. NR 232
• C. NR 242
• D. NR 532

Answer: (B)

The most common FCAW (Flux-Cored Arc Welding) structural steel wire is NR 232. This wire is specifically formulated for welding in various positions and is widely used because of its balance of mechanical properties and ease of use in construction and industrial applications. NR 232 is known for providing good penetration, a stable arc, and excellent impact toughness, making it suitable for a variety of structural steel applications. The other wires listed may be used for specific applications, but they do not have the same level of widespread usage or recognition in the field as NR 232. Each wire may have distinct characteristics tailored for particular conditions, such as specific joint configurations or material thicknesses, but NR 232 remains the preferred choice for many structural projects due to its versatility and reliability. This makes it the standard wire referenced in many welding specifications and practices in structural steelwork.
