1262F05 - ESAB Spoolarc 83 ER80S-D2 .035 MIG Wire 44lb Spool

Technical Overview of ESAB Spoolarc 83

The ESAB Spoolarc 83 is a premium low alloy steel MIG welding wire designed to meet the rigorous demands of high-strength fabrication. Classified under AWS A5.28 as ER80S-D2 and ER90S-D2, this wire is engineered with a specific chemical composition to enhance mechanical properties in critical applications. The formulation includes approximately 0.5% Molybdenum (Mo), a key alloying element that significantly increases the tensile strength and creep resistance of the weld deposit. This makes the wire particularly effective for applications requiring high strength in both the as-welded and stress-relieved conditions, ensuring structural integrity under load.

In addition to Molybdenum, Spoolarc 83 features elevated levels of Manganese (Mn) and Silicon (Si). These elements act as powerful deoxidizers, scavenging oxygen from the weld pool to prevent porosity and inclusions. From a metallurgical perspective, the high Mn/Si ratio promotes excellent wetting characteristics, allowing the molten pool to flow smoothly and fuse effectively with the base metal. This chemistry also provides the wire with a higher tolerance for surface contaminants, such as rust, mill scale, and oil, which are frequently encountered in industrial environments. The wire is manufactured to strict quality control standards, ensuring consistent diameter control (.035") and feedability.

This product is fully certified by the Canadian Welding Bureau (CWB) to CSA W48 standards, validating its use in regulated structural projects. It also meets military specifications (MIL-E-23765/2, 80S-3), demonstrating its suitability for defense and high-specification industrial sectors. The 44 lb (20 kg) spool is designed for industrial wire feeders, providing a substantial volume of material for continuous operation in manufacturing cells and fabrication shops. The wire is suitable for all-position welding, offering versatility for complex joint configurations found in piping systems and heavy machinery components.
