255061822 - ESAB AtomArc 9018 Low Hydrogen Stick Electrodes 1/8" (3.2mm) - 10lb Pack

Professional Grade E9018M Electrodes for Critical Fabrication

Welders seeking a reliable solution for high-strength steel applications turn to the ESAB AtomArc 9018. This 1/8" (3.2mm) stick electrode is formulated to provide superior weldability and mechanical properties, meeting the AWS E9018M H4R classification. It is specifically developed for welding low-alloy, high-tensile steels that have been quenched and tempered. If your project involves materials like T-1 or HY-80, the AtomArc 9018 offers the matching strength and toughness required to ensure a durable and safe bond.

The "H4R" designation indicates that this electrode has been tested for moisture resistance, ensuring low diffusible hydrogen levels in the weld metal. This is a critical factor in preventing cold cracking, particularly in thick sections or highly restrained joints. The electrode runs smoothly in all positions, offering a stable arc and manageable puddle control that professional welders appreciate. The operating amperage range of 70 to 100 Amps allows for flexibility depending on the material thickness and welding position, giving the operator fine-tuned control over heat input and penetration.

Packaged in a robust 10 lb hermetically sealed steel carton, these electrodes are protected from atmospheric moisture absorption during storage and transport. This packaging design is essential for maintaining the low-hydrogen characteristics of the flux coating. For welders in the field—whether on a bridge deck, in a shipyard, or repairing railcars—having a rod that performs consistently right out of the can is invaluable. The AtomArc 9018 delivers excellent notch toughness and ductility, making it suitable for structures subject to dynamic loading and harsh environmental conditions.

Performance Highlights:

• All-Position Capability: Welds effectively in flat, horizontal, vertical, and overhead positions.
• Moisture Resistance: H4R coating minimizes hydrogen cracking risks.
• High Tensile Strength: Delivers 92-95 ksi for robust structural connections.
• Quality Packaging: Hermetically sealed to preserve performance.
