OVERVIEW

Premium Stainless Steel Welding Wire for Clean Results

The Bonarc ER316LSi MIG Wire is a top-tier choice for fabricators demanding excellence in stainless steel welding. This 15kg spool of 0.035-inch wire is specifically engineered with a high silicon content, which significantly improves the wetting action of the weld metal. For professionals working in industries where aesthetic finish and corrosion resistance are paramount—such as food processing, pharmaceutical manufacturing, and architectural fabrication—this wire delivers superior results.

One of the standout features of this product is its "Low Carbon" (L) designation combined with high silicon (Si). The low carbon content is critical for preventing intergranular corrosion, ensuring that your welds remain durable even in harsh environments. Meanwhile, the added silicon helps the molten pool flow more smoothly, resulting in flatter beads with smoother tie-ins. This reduces the need for extensive post-weld grinding and polishing, saving you valuable time and labor costs on every project.

Designed for use with standard MIG welding equipment, this solid wire feeds smoothly thanks to Bonarc's precision winding and quality manufacturing processes. Whether you are welding tanks, piping systems, or marine hardware, the Bonarc 316LSi provides the consistency and arc stability required for high-quality production welding. The 15kg spool size is ideal for industrial setups, minimizing downtime caused by frequent spool changes.

Key Benefits:

  • Superior Finish: High silicon improves bead appearance.
  • Corrosion Resistant: Molybdenum content protects against pitting.
  • Efficient: Excellent feedability reduces bird-nesting and downtime.

FAQ

The 'Si' stands for Silicon. High silicon content improves the fluidity (wetting action) of the weld puddle, resulting in a smoother, flatter bead profile and better tie-in at the toes of the weld.

For stainless steel MIG welding with solid wire, a mixture of Argon with a small amount of CO2 (e.g., 98% Argon / 2% CO2) or Oxygen (98% Argon / 2% Oxygen) is typically recommended to stabilize the arc and improve wetting.

Yes, ER316LSi can be used to weld 304 stainless steel. It provides higher corrosion resistance than the base metal. However, ER308L is the standard filler for 304, so using 316LSi is often an upgrade or a matter of convenience if you only want to stock one wire.

This product comes on a 15kg (approximately 33 lbs) spool, which is a standard size for industrial wire feeders.

No, this is a solid MIG wire. It requires an external shielding gas cylinder to protect the weld pool.

This wire is designed to be run on DCEP (Direct Current Electrode Positive), also known as Reverse Polarity.

The wire diameter is 0.035 inches (approximately 0.9mm), which is a common all-purpose size for MIG welding.

You would choose 316LSi when appearance and speed are critical. The better wetting action allows for faster travel speeds and requires less post-weld grinding to achieve a smooth finish.
