ESAB 55003245V0 ELECTRODE, E7018 X 1/8″ OK55 9lb

The ESAB OK 55.00 E7018 1/8″ Stick Electrode is a low-hydrogen, high-strength welding rod designed for structural steel and heavy-duty applications. Manufactured from low-alloy steel, it provides a minimum tensile strength of 85,600 PSI (590 MPa) and meets CSA W48 and AWS E7018-1 H4R standards. This electrode operates on AC and DC+ polarity, delivering deep penetration, stable arc control, and excellent impact resistance at low temperatures. The VacPac® vacuum-sealed packaging prevents moisture absorption, ensuring low hydrogen content for crack-resistant, high-integrity welds.

This E7018 electrode is widely used for structural fabrication, heavy equipment repair, and shipbuilding, where strong, ductile, and defect-free welds are required. The basic coating minimizes spatter and allows for smooth slag removal, improving welding efficiency. With a length of 17 3/4 inches and a 1/8-inch diameter, it is suitable for mild steel grades A, D, and E, making it a preferred choice in industries that demand durable, high-performance welds in critical applications.

Features:

• Low-hydrogen formula: Reduces hydrogen-induced cracking, ensuring weld integrity.
• High tensile strength: Withstands 85,600 PSI (590 MPa) of stress, making it ideal for structural applications.
• Stable arc and deep penetration: Delivers strong fusion and minimal spatter for clean welds.
• Excellent low-temperature impact resistance: Ensures weld toughness in harsh environments.
• VacPac® vacuum-sealed packaging: Protects electrodes from moisture absorption, ensuring reliable weld performance.
