Welding Wire BA-S3Si (K415/25) [25Kg Spool]

Engineered for high productivity automated welding, our BA-S3Si Submerged Arc (SAW) wire is the industrial standard for heavy duty fabrication. This medium manganese, high silicon wire is designed to be used with a variety of agglomerated fluxes, providing excellent bead wetting, a smooth finish and superior mechanical properties.

The S3Si classification ensures a stable arc and high impact toughness, even at low temperatures. Supplied on massive 25kg K415 spools, this wire is built for continuous, high amperage duty cycles. Whether you are fabricating wind towers, pressure vessels, or massive structural beams, the BA-S3Si wire delivers the high deposition rates and consistent quality required for certified structural work.

Key Features

High Silicon S3Si Chemistry: Enhanced silicon content improves puddle fluidity and produces a flatter, smoother bead profile with excellent slag detachment.

Heavy Gauge Industrial Sizes:

- 2.4mm: Ideal for medium to heavy plate fabrication.

- 3.2mm: The versatile standard for heavy structural and longitudinal seams.

- 4.0mm: Maximum deposition for massive fill passes and thick wall vessels.

K415 Spool Format: Large 25kg wire baskets designed for industrial SAW wire feeders, reducing the frequency of spool changes.

Superior Weldability: Designed for high speed welding with minimal risk of porosity, even on slightly rusted or scaled plates.

Certified Performance: Meets international standards for critical structural and pressure rated applications.
