Lincoln Innershield NR-232 Mig Wire 2.0mm – 11.3kg Spool for Structural Seismic Welding

Product Overview

Lincoln Electric Innershield NR-232-MP is a premium self-shielded flux cored welding wire engineered for high-deposition, out-of-position welding in structural fabrication¡ªideal for seismic zone projects. With its fast-freezing slag system and penetrating arc, this 2.0mm diameter wire delivers consistent, high-quality welds on 4.8mm+ carbon steel, even in moderate wind conditions without tenting.

Core Specifications

Key Features & Benefits

• Seismic-Grade Performance: Meets AWS D1.8 seismic lot waiver requirements for critical structural projects
• All-Position Versatility: Fast-freezing slag system enables vertical/overhead welding with minimal spatter
• Wind-Resistant Operation: Stable arc performance in moderate wind without external shielding gas
• High Deposition Efficiency: Maximizes productivity for large-scale carbon steel fabrication
• Easy Slag Removal: Non-adherent slag reduces post-weld cleanup time

Applications

Perfect for seismic zone structural fabrication, bridge construction, industrial machinery, and heavy equipment manufacturing. Ideal for single or multiple pass welding on 3/16″ (4.8mm) and thicker carbon steel plates.

Quality Assurance

Manufactured by Lincoln Electric¡ªthe global leader in welding technology. Each spool undergoes rigorous testing to ensure consistent diameter, arc stability, and mechanical properties. Packaged in FEMA 353 compliant steel containers for secure storage and transportation.

Why Choose NR-232?

Unlike conventional flux cored wires, NR-232-MP combines high deposition rates with superior out-of-position control¡ªreducing welding time by up to 30% on vertical joints. Its seismic certification makes it the preferred choice for critical infrastructure projects requiring code compliance.
