The Hobart 418 E7018-1 Stick Electrode is a high-performance, low-hydrogen consumable designed for critical welding applications requiring superior mechanical properties. Engineered to meet the AWS E7018-1 classification, this electrode provides exceptional impact toughness at low temperatures (typically down to -45°C), making it the preferred choice for industries operating in harsh environments or adhering to strict structural codes. The 5.0mm diameter is specifically suited for heavy fabrication tasks where high deposition rates are necessary to maintain productivity on thick steel sections.
Manufactured by Hobart, a leader in welding filler metals, the 418 series is formulated with an iron powder coating that enhances deposition efficiency while maintaining a smooth, stable arc. This electrode is versatile enough to be used in all positions, although the 5.0mm size is most effectively utilized in flat and horizontal fillets due to the large weld pool. It operates reliably on both Direct Current Electrode Positive (DCEP) and Alternating Current (AC), providing flexibility for various power source configurations found in industrial settings.
One of the standout technical features of the Hobart 418 is its resistance to moisture pickup, which is critical for preventing hydrogen-induced cracking in high-strength steels. The 50lb hermetically sealed can ensures that the electrodes remain factory-fresh and ready for immediate use upon opening. For code-quality work, these rods deliver X-ray quality welds with excellent bead appearance and minimal spatter, reducing post-weld cleanup time and ensuring structural integrity in applications ranging from power generation to offshore construction.
This product is ideal for MRO professionals and procurement specialists sourcing materials for large-scale infrastructure projects. Its compliance with major welding codes and consistent chemical composition ensures repeatability and quality assurance across batches. Whether used for repairing heavy mining equipment or constructing pressure vessels, the Hobart 418 delivers the mechanical reliability demanded by engineering specifications.
