Welding Wire BA-S2Si (K415/25) [25Kg Spool]

Our BA-S2Si Submerged Arc (SAW) wire is the industry standard choice for high speed, automated welding of carbon and low alloy steels. This double deoxidised wire features a precisely controlled silicon and manganese content, ensuring a stable arc and excellent bead appearance across a wide range of welding parameters.

Designed for use with both active and neutral fluxes, the S2Si classification (AWS EM12K) is favoured for its superior deoxidising properties, which help to eliminate porosity even on materials with light mill scale or rust. Supplied on robust 25kg K415 spools, this wire is engineered for the long duty cycles required in shipbuilding, bridge construction, and general heavy engineering.

Key Features

Standard Industrial S2Si Chemistry: Balanced silicon and manganese levels provide a versatile weld deposit with high mechanical integrity.

Heavy-Duty Size Options:

- 2.4mm: Excellent for fillet welds and medium plate butt joints.

- 3.2mm: The most popular size for general structural fabrication and heavy plate.

- 4.0mm: Designed for maximum deposition rates in thick walled applications.

Superior Surface Finish: Precision copper coating ensures smooth wire feeding and protects against corrosion during storage.

K415 Wire Basket Spool: Heavy duty 25kg capacity ensures compatibility with all major industrial SAW wire feeders.

Broad Flux Compatibility: Performs exceptionally well with a variety of agglomerated and fused fluxes for high quality, X-ray clear welds.
