OVERVIEW

ERNiFeCr-2 TIG Welding Rod – Alloy 718

The 718 TIG Rod is a specialized nickel-based filler metal classified as AWS A5.14 ERNiFeCr-2. Designed for the Gas Tungsten Arc Welding (GTAW) process, this 3/32" rod is essential for fabricating and repairing components made from Alloy 718 (UNS N07718) and similar precipitation-hardenable nickel alloys. This filler metal is widely utilized in industries where components are subjected to high stress and extreme temperature fluctuations, such as aerospace, power generation, and chemical processing.

Alloy 718 filler metal is distinguished by its addition of niobium (columbium) and molybdenum, which work together to provide high strength without the need for complex heat treatments immediately after welding, although post-weld heat treatment is recommended to achieve full properties. The weld deposit exhibits excellent corrosion resistance and is particularly resistant to radiation damage and oxidation. The sluggish nature of the molten puddle requires a skilled hand and clean preparation, but the resulting weld offers superior fatigue life and tensile strength.

This product comes in a durable 10lb tube to protect the rods from moisture and contamination. The 36-inch length is standard for manual TIG applications, allowing for precise control over the heat input and fill rate. For welders working on rocket motors, spacecraft, or downhole drilling tools, the ERNiFeCr-2 rod provides the metallurgical compatibility required for safety and longevity.

FAQ

The AWS classification is ERNiFeCr-2, as per AWS A5.14 specifications.

It is primarily designed for welding Inconel Alloy 718, Alloy 706, and Alloy X-750.

While the alloy has good weldability, post-weld heat treatment (aging) is typically required to develop the full strength and properties of the precipitation-hardened alloy.

100% Argon is the most common shielding gas. For thicker sections or to increase heat input, an Argon/Helium mix may be used.

Yes, Alloy 718 retains excellent mechanical properties at cryogenic temperatures, making it suitable for liquid gas storage and aerospace applications.

Store in a cool, dry place within the original packaging to prevent contamination from moisture, dust, or oil, which can cause weld defects.

These rods are 3/32 inch (approximately 2.4 mm) in diameter.
