What is the AWS classification of the Lincoln ED019587 Lincolnweld 781 Submerged Arc SAW Flux, 50 lb Bag?

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 process is the Lincoln ED019587 Lincolnweld 781 Submerged Arc SAW Flux, 50 lb Bag designed for?

The Lincoln ED019587 Lincolnweld 781 Submerged Arc SAW Flux, 50 lb Bag 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 diameter is the Lincoln ED019587 Lincolnweld 781 Submerged Arc SAW Flux, 50 lb Bag 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.

Q: What spool or coil size is the Lincoln ED019587 Lincolnweld 781 Submerged Arc SAW Flux, 50 lb Bag available in?

The Lincoln ED019587 Lincolnweld 781 Submerged Arc SAW Flux, 50 lb Bag 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 ED019587 Lincolnweld 781 Submerged Arc SAW Flux, 50 lb Bag 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.
