OVERVIEW

High-Performance Low Hydrogen Welding Electrodes

The Hobart 418 is a premium quality carbon steel electrode designed for critical welding applications requiring high tensile strength and low hydrogen levels. Classified as E7018 H4R and E7018-1 H4R, this electrode is engineered to meet the rigorous demands of industries such as petrochemical, power generation, and heavy construction. The "H4R" designation signifies its resistance to moisture absorption, a critical factor in preventing hydrogen-induced cracking in high-stress welds. This makes the Hobart 418 an excellent choice for structural steel, boiler pressure vessels, and offshore rig fabrication where weld integrity is paramount.

Packaged in a 50 lb hermetically sealed can, these 1/8-inch electrodes are protected from environmental humidity, ensuring they are factory-fresh upon opening. This packaging reduces the immediate need for rod ovens if used within the specified exposure time, streamlining workflow on job sites. The electrode features a tensile strength of 78,500 psi and a yield strength of 65,500 psi, providing robust mechanical properties for load-bearing structures. It is compatible with both DCEP (Direct Current Electrode Positive) and AC (Alternating Current), offering flexibility depending on the available power source and specific job requirements.

Fabricators rely on the Hobart 418 for its versatility across all welding positions, including vertical up and overhead. Its formulation allows for single and multiple pass applications on mild, low alloy, and fine grain steels. Whether used for infrastructure repair, railcar construction, or mining equipment fabrication, this electrode delivers consistent, code-quality results. By choosing Hobart 418, industrial supply managers ensure their teams are equipped with a consumable that balances high-performance specifications with practical usability in the field.

FAQ

Hobart 418 is classified as AWS E7018 H4R and E7018-1 H4R.

H4R indicates that the electrode has a very low diffusible hydrogen limit (less than 4ml per 100g) and is moisture resistant, reducing the risk of hydrogen cracking.

The tensile strength is approximately 78,500 psi.

Yes, Hobart 418 operates on both AC and DCEP (DC+) currents.

Yes, it is an all-position electrode suitable for flat, horizontal, vertical up, and overhead welding.

Hobart 418 is known for easy slag removal, often requiring minimal chipping.

Yes, it has good wetting action and can be used to weld even when the surface is slightly dirty or rusty.

This item comes in a 50 lb (22.7 kg) hermetically sealed can.
