OVERVIEW

Exocor ER309L TIG Filler Metal – 0.035" Diameter

Take on complex fabrication challenges with confidence using Exocor ER309L TIG Welding Rods. Known in the trade as the "problem solver" for stainless steel welding, the 309L alloy is essential for any shop that deals with mixed materials. If you need to weld a stainless bracket to a mild steel frame, or repair a casting where the exact grade is unknown but likely stainless, this is the rod to reach for. The 0.035-inch diameter offers fine control for delicate work, root passes, or thin-wall tubing, allowing you to lay down precise beads with minimal heat input.

The chemistry of this rod is formulated to handle dilution from carbon steel base metals while still retaining enough ferrite to prevent hot cracking. This makes it incredibly forgiving and robust. The low carbon content ensures that your welds remain resistant to intergranular corrosion, a common failure point in standard stainless welds exposed to harsh environments. Each 36-inch rod is manufactured to strict AWS A5.9 standards, ensuring consistent diameter, cleanliness, and chemical composition from the first rod in the tube to the last.

Why Choose Exocor 309L?

Welders appreciate the smooth wetting action and clean puddle visibility provided by Exocor consumables. The rod flows easily, creating a flat, aesthetically pleasing bead profile that requires minimal post-weld grinding or cleaning. Whether you are working on custom automotive exhaust systems, industrial kitchen fit-outs, or heavy equipment repair, having a 10lb tube of ER309L on hand ensures you are ready for dissimilar metal joints at a moment's notice.

FAQ

ER309L is primarily used for welding dissimilar metals, such as joining stainless steel to carbon steel, or for welding Type 309 stainless steel.

For TIG welding with ER309L, 100% Argon is the standard shielding gas required to protect the weld pool.

While it can physically join them, it is not recommended due to cost and potential cracking issues. Use ER70S-6 for mild steel to mild steel applications.

The 'L' stands for 'Low Carbon'. This indicates a maximum carbon content of 0.03%, which helps prevent intergranular corrosion.

0.035" is on the thinner side for TIG rods, making it excellent for welding thin-gauge materials or for precise root passes.

Use DCEN (Direct Current Electrode Negative), also known as Straight Polarity, for TIG welding stainless steel.

The count varies by diameter, but for 0.035" wire, there are significantly more rods per pound compared to thicker 1/16" or 3/32" rods.

Yes, ER309L is excellent for the first layer of cladding stainless steel onto carbon steel to create a buffer layer.
