OVERVIEW

Exocor E312-16 Stick Electrodes: The Ultimate Problem Solver

The Exocor E312-16 Stick Electrodes (3/32") are premium stainless steel welding rods designed for the most demanding maintenance and repair applications. Often referred to as the "universal" electrode, the E312-16 classification represents a duplex microstructure containing a substantial amount of ferrite within an austenitic matrix. This unique composition provides extremely high tensile strength and exceptional resistance to cracking, even when welding under high restraint.

These electrodes are specifically engineered to weld dissimilar steels, such as joining carbon steel to stainless steel, or for welding steels with unknown compositions. They are an essential tool for any maintenance shop, capable of handling high-carbon steels, tool steels, spring steels, and manganese steels that would otherwise be prone to weld failure. The 3/32" diameter allows for precise control on thinner materials while still providing enough deposition for structural repairs.

Exocor ensures excellent weldability with this rod, offering a smooth arc, low spatter, and self-releasing slag. It operates effectively on both AC and DC+ polarity, making it versatile for various power sources. Whether you are repairing a broken leaf spring, building up a worn shaft, or joining incompatible metal grades, the Exocor E312-16 delivers a sound, defect-free weld deposit every time.

Key Performance Characteristics

  • Crack Resistance: High ferrite levels prevent hot cracking in the weld metal.
  • Versatility: Bonds to almost any steel, including "hard-to-weld" grades.
  • Operability: Smooth arc with easy restrike and slag removal.

FAQ

E312-16 is used for welding dissimilar steels, high-carbon steels, tool steels, and steels of unknown composition. It is known for its high crack resistance.

The typical amperage range for a 3/32" (2.4mm) E312-16 electrode is approximately 40 to 80 Amps, depending on the base metal thickness and position.

Yes, Exocor E312-16 electrodes are designed to operate on both AC and DC+ (Reverse Polarity) current.

While E312-16 has a rutile coating and is less sensitive than low-hydrogen rods, it is best practice to store them in a dry place. If they absorb moisture, re-baking at 250°F-300°F for an hour can help, but they are generally used directly from the package for maintenance.

Yes, the E312-16 coating allows for all-position welding, including vertical-up and overhead, though smaller diameters like 3/32" are easier to control in these positions.

It is called universal because its unique metallurgical composition allows it to successfully weld a vast range of steel grades that are otherwise incompatible or prone to cracking.

E309 is typically used for joining 304 stainless to mild steel. E312 has higher tensile strength and better crack resistance, making it superior for higher carbon steels, tool steels, and more difficult dissimilar joints.
