EX80SNI10000350M00 - ER80S-Ni1 .035 Low Alloy MIG Wire 33lb Spool

Technical Overview of ER80S-Ni1 MIG Wire

The Exocor ER80S-Ni1 .035" MIG Wire is a premium low-alloy solid wire formulated to meet the rigorous demands of high-strength structural welding. Classified under AWS A5.28 as ER80S-Ni1, this consumable is characterized by its nominal 1% nickel composition. The addition of nickel significantly refines the grain structure of the weld metal, providing exceptional notch toughness and impact resistance at sub-zero temperatures, typically down to -45°C (-50°F). This makes it an essential choice for industries operating in arctic or harsh winter environments where standard carbon steel wires may suffer from brittle fracture.

Beyond its mechanical properties, ER80S-Ni1 is widely specified for welding ASTM A588 and other weathering steels. When welded, the deposit develops a patina similar to the base metal, ensuring aesthetic uniformity and consistent corrosion resistance across the assembly. This wire is designed for use with shielding gases such as Argon/CO2 blends or 100% CO2, offering versatility in various shop and field conditions. The 33lb (15kg) spool is precision layer-wound to minimize tangling and ensure consistent wire feed speed, which is critical for maintaining arc stability and reducing downtime in automated or semi-automatic processes.

Engineers and metallurgists select this wire for critical applications involving offshore piping, heavy equipment fabrication, and structural components requiring tensile strengths in the 80,000 psi range. Its ability to produce X-ray quality welds with minimal spatter and excellent bead profile makes it a reliable option for code-work fabrication.
