OVERVIEW

Weld Like a Pro with Exocor ER309L

When you are faced with the tricky job of welding stainless steel to mild steel, you need a rod that you can trust not to crack. That is exactly what the Exocor Executive ER309L TIG rod is built for. Known in the shop as the "universal problem solver," 309L is your go-to filler metal for joining dissimilar metals. Whether you are welding a stainless bracket onto a carbon steel frame or doing overlay work, this rod lays down smooth and holds tight.

The 0.035-inch diameter is perfect for a wide range of material thicknesses, giving you enough deposition for medium gauge work while still allowing for fine control on thinner sections. Exocor's "Executive" line means you are getting premium quality wire that is clean and consistent. You won't be fighting dirty wire or inconsistent feeding here. The rod melts cleanly, wets out the toes of the weld perfectly, and leaves a bead that makes you look good. The slag (silica islands) is minimal and floats to the top for easy cleanup.

This 10lb tube is the standard size for professional shops, keeping your filler metal protected from moisture and shop dirt until you are ready to burn it. If you are doing maintenance repair operations (MRO) or custom fabrication where material types are mixed, keep a tube of 309L on your cart. It prevents the headaches of cracking that happen if you try to use standard 308L on mild steel. Get the right tool for the job and stack dimes with confidence.

FAQ

ER309L is primarily used for welding dissimilar metals, specifically joining 300-series stainless steel to carbon or low-alloy steels. It is also used for the first layer of cladding on carbon steel.

The 'L' stands for 'Low Carbon'. It indicates that the carbon content is restricted to a maximum of 0.03% to prevent carbide precipitation and intergranular corrosion.

For TIG welding (GTAW) with ER309L, 100% Argon is the standard shielding gas.

While it is physically possible, it is not recommended or cost-effective. You should use an ER70S-6 rod for mild steel to mild steel. 309L is specifically for stainless-to-mild steel or stainless-to-stainless applications.

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

Yes, ER309L is suitable for certain cryogenic applications, though specific impact testing requirements should be verified based on the service temperature and code requirements.

The count varies by diameter, but for 0.035" rods, there are significantly more rods per pound than thicker diameters. It is sold by weight, not piece count.

ER309L has a lower carbon content than ER309. This makes ER309L more resistant to intergranular corrosion, making it the preferred choice for most modern industrial applications.
