OVERVIEW

Smoother Stainless Welds with Hobart 316LSi

If you are welding stainless steel and struggling with sluggish puddles or ropey beads, the Hobart 316L Hi Sil .035" MIG wire is the solution you need. The "Hi Sil" stands for High Silicon, a formulation tweak that changes how the molten metal behaves under the arc. Unlike standard stainless wire that can sometimes feel stiff or pile up, this wire wets out beautifully. The puddle flows out to the edges more easily, giving you that professional, flat bead appearance that requires far less grinding and polishing after the hood goes up.

This wire is a workhorse for the food and beverage industry, where smooth welds aren't just about looks—they are about sanitation. Rough welds trap bacteria, but the smooth wash-in you get with this Hobart wire makes sanitary finishing much faster. It is also perfect for custom fabrication, marine parts, and petrochemical equipment where 316L base material is used. The 30lb spool size is ideal for shop use, fitting standard wire feeders and ensuring you have enough material to keep the arc on for long shifts without constant changeovers.

Designed for DCEP polarity, this wire runs smooth and stable. Whether you are running a spray transfer for heavy deposition or a short circuit on thinner gauges, the feedability of Hobart wire ensures you spend less time troubleshooting your gun and more time laying dimes. It delivers the corrosion resistance you expect from 316L, protecting your projects from rust and chemical attack for years to come.

FAQ

The main difference is the silicon content. ER316LSi has higher silicon (Hi Sil), which improves the fluidity of the weld puddle (wetting action) and produces a flatter, smoother weld bead compared to standard ER316L.

For MIG welding with ER316LSi, a mixture of 98% Argon and 2% Oxygen or a trimix of Helium/Argon/CO2 is commonly used. Argon/CO2 mixes (like 98/2 or 95/5) can also be used but keep CO2 low to prevent carbon pickup.

Yes, you can use 316LSi to weld 304 stainless steel. However, 308L is the standard filler for 304. Using 316L on 304 adds molybdenum to the weld, which is acceptable but more expensive than necessary.

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

This product comes on a 30lb (approx. 13.6kg) spool, which is a standard size for industrial wire feeders.

Yes, the 316L alloy is the standard for food and beverage applications due to its excellent corrosion resistance. The smooth bead profile of the Hi Sil version also aids in sanitary finishing.

Yes, when welding with stainless steel wire, you should always use a Teflon or plastic liner in your MIG gun to prevent contamination from steel shavings that can occur with steel liners.

The 'L' stands for 'Low Carbon'. This reduces the risk of carbide precipitation during welding, which maintains the corrosion resistance of the stainless steel in the heat-affected zone.
