OVERVIEW

Hobart Hoballoy 8018-C3 1/4" Stick Electrodes

The Hobart Hoballoy 8018-C3 is a premium low-alloy, low-hydrogen stick electrode designed for critical welding applications requiring higher tensile strength and superior toughness. This specific variant comes in a substantial 1/4-inch diameter, making it a heavy-hitter for large-scale fabrication where high deposition rates are essential. Packaged in a 50lb hermetically sealed can, these electrodes are protected from moisture absorption, ensuring they deliver X-ray quality welds right out of the package.

Engineered with a nominal 1% nickel content, the 8018-C3 classification is specifically formulated to weld high-strength low-alloy (HSLA) steels with tensile strengths in the 80,000 psi range. The nickel addition is crucial as it enhances the weld metal's notch toughness, particularly at sub-zero temperatures (typically down to -40°F). This makes the Hoballoy 8018-C3 an excellent choice for industries operating in cold environments or where dynamic loading is a concern, such as heavy equipment manufacturing, shipbuilding, and structural steel erection.

The 1/4-inch diameter of this electrode indicates it is intended for heavy plate welding, typically in the flat and horizontal positions. The iron powder coating facilitates a smooth, stable arc with minimal spatter and easy slag removal, allowing welders to lay down significant amounts of metal efficiently. It is also a preferred filler metal for welding weathering steels, such as ASTM A588, where color match and corrosion resistance are secondary to structural integrity.

Key Applications:

  • Heavy structural steel fabrication
  • Shipbuilding and barge construction
  • Mining and earthmoving equipment repair
  • Piping systems requiring 80ksi strength
  • Welding of 1% nickel steels and weathering steels

At Josef Gas, we provide high-quality filler metals like the Hobart Hoballoy series to ensure your projects meet rigorous engineering standards. Whether you are repairing heavy machinery or fabricating structural components, the 8018-C3 offers the reliability and performance professional welders demand.

FAQ

E8018-C3 electrodes are used for welding high-strength low-alloy steels, particularly those requiring 80,000 psi tensile strength and good impact toughness at low temperatures.

The 'C3' suffix indicates the chemical composition of the electrode, specifically that it contains nominally 1% Nickel, which improves the weld's toughness.

A 1/4-inch diameter E8018 electrode typically operates in the range of 300 to 400 amps, depending on the specific machine and position, though it is generally limited to flat and horizontal positions due to the large puddle.

Yes, like all low-hydrogen (EXX18) electrodes, once the hermetically sealed can is opened, they should be stored in a holding oven at 250°F-300°F to prevent moisture pickup.

The 1/4-inch diameter is generally too large for vertical or overhead welding due to the fluidity and volume of the weld pool. It is best suited for flat and horizontal positions.

Yes, E8018-C3 is often used to weld weathering steels (like ASTM A588) because its mechanical properties and nickel content provide a good match for the base metal.

The main difference is strength and composition. 7018 has a minimum tensile strength of 70,000 psi, while 8018-C3 has 80,000 psi and contains 1% nickel for better low-temperature toughness.

It can be operated on both DCEP (Direct Current Electrode Positive) and AC (Alternating Current).
