OVERVIEW

Premium Stainless Steel Welding Wire for Industrial Fabrication

The Bonarc ER308LSi .045" MIG Wire is a high-performance stainless steel welding consumable designed for professional industrial applications. Packaged in a substantial 15kg spool, this wire is engineered to meet the rigorous demands of continuous manufacturing environments. The "LSi" designation indicates a low carbon content combined with high silicon, a formulation that significantly enhances the welding characteristics of the material.

This wire is specifically developed for welding austenitic stainless steels of the 304 and 304L grades. The higher silicon content improves the fluidity of the weld pool, resulting in exceptional wetting action. This allows the molten metal to flow more smoothly into the toes of the weld, creating a flatter bead profile and reducing the need for post-weld grinding or finishing. The low carbon content is critical for maintaining corrosion resistance, particularly by minimizing carbide precipitation at the grain boundaries, which protects the integrity of the weldment in corrosive environments.

Key Performance Benefits:

  • Superior Wetting: The high silicon formula ensures the weld metal washes in smoothly, ideal for fillet welds and cosmetic applications.
  • Consistent Feeding: Precision layer winding prevents tangles and ensures stable arc characteristics, even at higher wire feed speeds.
  • Versatility: Suitable for a wide range of industries, including food and beverage processing, pharmaceutical equipment manufacturing, and architectural metalwork.

For fabricators requiring reliable, high-quality stainless steel joins, the Bonarc ER308LSi offers the perfect balance of mechanical strength and aesthetic finish. It is compatible with standard MIG welding equipment and performs best with Argon/CO2 or Argon/Oxygen shielding gas mixtures.

FAQ

The 'Si' stands for Silicon. ER308LSi has a higher silicon content than standard ER308L, which improves the fluidity of the weld pool (wetting action) and results in a flatter, smoother bead profile.

For MIG welding stainless steel, a mixture of Argon and CO2 (e.g., 98% Argon / 2% CO2) or Argon and Oxygen is typically recommended to ensure a stable arc and good corrosion resistance.

No, ER308LSi is designed for welding 304/304L stainless to itself. For welding stainless steel to mild steel, you should use an ER309L wire.

This is a 15kg spool, which is approximately 33 lbs.

No, this is a solid MIG wire that requires an external shielding gas.

.045 inches is approximately 1.2mm.

It is primarily used for welding ASTM 304 and 304L stainless steels, as well as 302 and 321 grades in some applications.
