OVERVIEW

Master Dissimilar Metal Welding with Exocor Executive ER309L

When you are faced with the challenge of welding stainless steel to mild steel, the Exocor Executive ER309L TIG Rod is your go-to solution. This 2.5mm (3/32") filler rod is engineered to handle the complexities of joining different metal grades with ease. Known among professional welders for its smooth running characteristics, the Executive series rods feature a bright, clean finish that promotes a stable arc and excellent puddle fluidity. This means you spend less time fighting the puddle and more time laying down perfect, aesthetically pleasing beads.

The "L" in ER309L stands for Low Carbon, a critical feature that protects your work from intergranular corrosion and cracking. This makes it incredibly versatile for shop repairs, custom fabrication, and maintenance work where you might be welding brackets, mounts, or fittings of one material type onto a structure of another. It is also widely used for the first pass (root pass) when cladding carbon steel with stainless, acting as a safe transition layer that prevents the carbon from the base metal from contaminating your final stainless passes.

Packaged in a durable 10lb tube, these rods are protected from moisture and contaminants, ensuring they are fresh and ready to weld when you pop the cap. The 3/32" diameter is a versatile size, perfect for medium-gauge materials and general-purpose TIG applications. With Exocor's commitment to quality, you can trust that every rod in the tube will perform consistently, giving you the confidence to tackle critical joints without worry. Upgrade your TIG consumables inventory with Exocor Executive and experience the difference premium filler metal makes in your daily welding operations.

FAQ

ER309L is primarily used for welding dissimilar metals, such as joining 300-series stainless steel to carbon or mild steel. It is also used for the first layer of cladding stainless onto carbon steel.

For TIG welding (GTAW) with ER309L, 100% Argon is the standard shielding gas. Helium mixtures can be used for greater penetration in thicker sections.

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

While it can be used, ER308L is the correct and more economical choice for welding 304 to 304. ER309L is specifically designed for dissimilar joints or buffer layers.

Stainless steel TIG welding is typically performed using Direct Current Electrode Negative (DCEN), also known as straight polarity.

The number of rods varies by diameter. For 3/32" (2.5mm) rods, there are typically around 120-140 rods in a 10lb package, depending on the exact length and density.

ER309L is suitable for heat treatment applications and general service temperatures. However, for continuous high-temperature service (above 700°F/370°C), other alloys might be preferred to avoid sigma phase embrittlement.

Standard TIG cut lengths are typically 36 inches (approx. 914mm) long.
