What process is the Lincoln Lincore 30-S SAW Welding Wire designed for?

The Lincoln Lincore 30-S 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 30-S SAW Welding Wire?

The Lincoln Lincore 30-S SAW Welding Wire carries AWS Lincoln Lincore 30-S SAW Welding Wire classification. In SAW, the wire/flux combination determines the weld deposit chemistry and mechanical properties — the wire class and flux class are always specified together. Always verify the flux is approved for use with this wire in your Welding Procedure Specification (WPS).

What diameter is the Lincoln Lincore 30-S SAW Welding Wire available in?

The Lincoln Lincore 30-S SAW Welding Wire is available in 1/8, 3/32 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.

What spool or coil size is the Lincoln Lincore 30-S 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 30-S 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.
