What process is the Lincoln Lincore 420 Metal-Cored Submerged Arc SAW Welding Wire designed for?

The Lincoln Lincore 420 Metal-Cored Submerged Arc SAW Welding Wire is used in Submerged Arc Welding (SAW), a high-deposition welding process where the arc is shielded by a blanket of granular flux rather than shielding gas. SAW is used primarily in the flat and horizontal positions for welding structural plate, pressure vessels, pipelines, ship hulls, and heavy fabrication. It produces deep penetration, high deposition rates, and excellent weld quality with minimal spatter.

What is the AWS classification of the Lincoln Lincore 420 Metal-Cored Submerged Arc SAW Welding Wire?

SAW wire AWS classification (e.g., EH14 for high-manganese wire, EM12K for medium-manganese wire, EA2 for low-alloy wire) specifies the wire chemistry. The wire classification must be paired with a compatible flux classification that together meet the WPS deposit property requirements. Check the flux manufacturer's compatibility chart before combining wire and flux.

What diameter is the Lincoln Lincore 420 Metal-Cored Submerged Arc SAW Welding Wire available in?

Common SAW wire diameters range from 5/64 in to 7/32 in. Smaller diameter wire (5/64, 3/32 in) suits lower heat-input applications, tight-groove work, and thinner plate. Larger diameter wire (5/32, 3/16, 7/32 in) maximizes deposition rate for heavy plate and multi-pass structural welds. Consult the wire manufacturer's parameter chart for amperage, voltage, and travel speed by diameter.

What spool or coil size is the Lincoln Lincore 420 Metal-Cored Submerged Arc SAW Welding Wire available in?

SAW wire is supplied in various coil weights from 25 lb coils to 600 lb reels, depending on the wire diameter and supplier. Heavy production SAW systems use large coils (300–600 lb) to minimize wire change-over time. Ensure your SAW wire feeder head is configured for the specific coil diameter and weight of the product ordered.

How should I store the Lincoln Lincore 420 Metal-Cored Submerged Arc SAW Welding Wire to maintain weld quality?

Store SAW wire in a clean, dry environment. Surface rust on SAW wire can introduce hydrogen into the weld deposit, increasing the risk of porosity and cold cracking in susceptible base materials. Lightly rusted wire can sometimes be cleaned with a dry cloth, but wire with heavy surface oxidation should be discarded. Keep wire coils sealed in their original packaging until ready for use and store at controlled room temperature with low humidity.
