Lincoln Electric Lincore 8620 ED020788 Flux-Core Wire 1/8" – 50 lb

Q: What process is the Lincoln ED020788 Lincore 8620 Metal-Cored Submerged Arc SAW Welding Wire, 1/8 in, 50 lb Coil designed for?

The Lincoln ED020788 Lincore 8620 Metal-Cored Submerged Arc SAW Welding Wire, 1/8 in, 50 lb Coil 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.

Q: What is the AWS classification of the Lincoln ED020788 Lincore 8620 Metal-Cored Submerged Arc SAW Welding Wire, 1/8 in, 50 lb Coil?

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.

Q: What diameter is the Lincoln ED020788 Lincore 8620 Metal-Cored Submerged Arc SAW Welding Wire, 1/8 in, 50 lb Coil available in?

The Lincoln ED020788 Lincore 8620 Metal-Cored Submerged Arc SAW Welding Wire, 1/8 in, 50 lb Coil is available in 1/8 diameter. SAW wire diameters range from 3/32 in (for narrow-groove and single-pass applications) to 1/4 in or larger (for heavy plate, multi-pass). Larger diameter wire allows higher amperage and deposition rates; smaller diameter wire permits more precise control of heat input for tighter bead geometry or narrower grooves.

Q: What spool or coil size is the Lincoln ED020788 Lincore 8620 Metal-Cored Submerged Arc SAW Welding Wire, 1/8 in, 50 lb Coil available in?

The Lincoln ED020788 Lincore 8620 Metal-Cored Submerged Arc SAW Welding Wire, 1/8 in, 50 lb Coil is available in 50 lb coil/spool sizes. SAW wire is commonly supplied as coils or on large spools (300–600 lb) for automated welding systems. Smaller coils (25–50 lb) suit semi-automatic and lower-volume applications. Use of the correct spool hub adapter for your SAW head is required for large-coil operation.

Q: How should I store the Lincoln ED020788 Lincore 8620 Metal-Cored Submerged Arc SAW Welding Wire, 1/8 in, 50 lb Coil 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.
