OVERVIEW

Smooth Feeding, Beautiful Beads: Exocor 316LSi MIG Wire

Take your stainless steel welding projects to the next level with Exocor's ER316LSi .045" MIG wire. If you've ever struggled with sluggish weld puddles or ropey beads when welding stainless, the "Si" in this wire is the solution you've been looking for. The increased silicon content acts as a deoxidizer and improves the fluidity of the puddle, allowing the metal to wet out smoothly at the edges. This means you get a flatter, better-looking weld right out of the gun, saving you valuable time on grinding and polishing later.

This 33lb spool is built for the professional welder who needs consistency. Exocor's precision winding ensures the wire feeds smoothly through your gun liner without tangling or surging, giving you a stable arc from the first inch to the last. It is specifically designed for welding 316 and 316L stainless steels, commonly found in food service equipment, brewery tanks, and marine hardware. Because it is a 316 grade, it offers excellent protection against rust and corrosion, even in salty or acidic environments.

Perfect for shop fabrication, this .045" wire offers high deposition rates for thicker materials while maintaining excellent control. The low carbon content protects your work from intergranular corrosion, ensuring your welds last as long as the base metal. Whether you are repairing a chemical tank or fabricating custom stainless fixtures, this wire gives you the professional finish and structural integrity your customers demand.

FAQ

The 'Si' stands for Silicon. ER316LSi has a higher silicon content (0.65-1.00%) compared to standard ER316L. This improves the 'wetting' action of the weld puddle, allowing it to flow better and create a smoother, flatter bead profile.

For MIG welding with ER316LSi, a mixture of 98% Argon and 2% CO2 is commonly used for spray arc transfer. For short circuit transfer or better color match, a Tri-mix gas (90% Helium, 7.5% Argon, 2.5% CO2) is often recommended.

Yes, you can weld 304 stainless with 316LSi wire, and it will produce a strong, corrosion-resistant weld. However, it is generally more expensive than 308L wire, which is the standard filler for 304 stainless.

This wire is designed for DCEP (Direct Current Electrode Positive), also known as Reverse Polarity.

Yes, the Molybdenum content in 316LSi provides excellent resistance to pitting corrosion caused by chlorides, making it ideal for marine environments.

This is a standard 33lb (15kg) spool, typically 12 inches (300mm) in diameter, designed to fit most industrial wire feeders.

Generally, no. The 'L' (Low Carbon) grade prevents carbide precipitation, meaning the weld retains corrosion resistance without the need for annealing in most applications.
