TIG welding stainless steel filler rods are available in your favorite welding stores. Whether you're a professional welder or just a hobbyist, it's important to know how these rods work and what they can do for your TIG welding stainless steel pipe or other projects.

Dive deeper into this article and go over some of the basics of TIG welding stainless steel rods so that you know how to TIG weld stainless steel.

The TIG Welding Filler Rods

TIG welding filler rods are for use in TIG welding. The technique is a manual one, and it's often used when there isn't enough purchase on the two metal pieces to hold them together with a different technique.

In order to fill in gaps from missing filler metal at joints or holes where arc or plasma is excluded, the TIG welding filler rods are introduced into the joint before it's welded. The rod can then be drawn out after it cools down, leaving a residue that looks similar to that of a cane sugar surface when viewed under careful examination.

Types of TIG Welding Filler Rods

There are different types of TIG welding filler rods available for use. The flux-coated rods can be used to fill in an area where the metal is porous. However, the flux will need to be cleaned off with a little bit of acetone or other solvents before the rod is introduced into the joint.

The flux-less welding rod is different because it doesn't have any type of coating on it. This one is used when there's no need to remove any residue because it cleans itself off after cooling down.

The single-aluminum tungsten electrode filler rods are made from tungsten wire that has been set into alumina clay which has then been fired at a lower temperature. This material is specifically designed for welding aluminum, and it can offer a great weld bead.

The tungsten inert gas (TIG) welding filler rods are made from pure tungsten that's been drawn into a wire. The rod is then put into an inert atmosphere so that the tungsten won't contaminate the weld area with oxides.

When you're looking to purchase TIG welding filler rods, make sure to get the right type for your project. Different types of metals will require different types of filler metal to create a successful weld. If you're not sure which type of rod to use, talk to someone who has experience with TIG welding, and they'll be able to help you out.

TIG Welding Stainless Steel Fillers in the Market

Some of the more popular TIG welding stainless steel filler rods on the market include:

The FabCO® 308LT1

FabCO® 308LT1

The FabCO® 308LT1 is a line of stainless welding fillers under Hobart—a well-known provider of quality metal fillers since 1958. The 308LT1 is perfect for joining common austenitic TIG welding stainless steel settings like 304, 304L, 321, CF-8, and CF-3. This welding filler also provides effective resistance against intergranular corrosion.

The application of this filler metal can be in single and multiple passes as well as direct current electrode positive (DCEP).

The ESAB OK Tigrod 318Si

ESAB OK Tigrod 318Si

ESAB has been around since 1937, so it's an established company worth looking into when purchasing products because you know you'll receive high-quality items. They're affordable too, making them perfect if your budget is limited.

The OK Tigrod 318Si is made from chromium-nickel-molybdenum perfect for welding Cr-Ni-Mo, and Cr-Ni stabilized or non-stabilized steels. It's bare, stabilized, and corrosion-resistant. These TIG metal fillers are powered with niobium which improves their resistance to intergranular corrosion of the weld. Because of niobium, the filler is recommended for temperatures up to 400°C.

It also has high silicon content for improved welding performance.

The WELDER'S CHOICE ER308L stainless steel TIG welding rods

Harris Ten Gauge Shelf-Shielding Mild Steel Wire

Harris Ten Gauge Shelf-Shielding Mild Steel Wire is perfect if you're looking for an affordable filler metal option. It welds cleanly and leaves behind very little slag, making the post-weld cleanup process much easier than with other products on the market.

This mild steel filler is a self-shielded carbon steel wire perfect for lap welds and single-pass fillets. Its innovative composition delivers the following features:

  • A recommended DC straight polarity.
  • Minimizes burn through thin sheet metal.
  • Perfect for plain and galvanized steel.
  • An excellent option for 110 volt welding machines, which doesn't require a gas bottle or whatever gas you use for TIG welding stainless steel.
  • Welds a wide range of steel thickness and is excellent for vertical down welding.
  • You can easily remove the slag and can weld in windy conditions.
The LINCOLN® TIG 308LSI

Lincoln® TIG 308LSi

The Lincoln Electric Tigrod 308LSi is a top-quality product perfect for welding stainless steel. It offers excellent weld bead quality and produces very little spatter, making it a great choice if you're looking to get the most out of your TIG welding project.

Start Welding!

The use of TIG welding filler rods can be a useful way to get your project started. They add strength and durability, but it's also important to realize that they're not going to do all of the work for you. The right tools, gears, and accessories are required to start off with any type of metal.

Ensure you have what you need before using these techniques on your own projects!
