255113326 - ESAB AtomArc T 3/32" E11018M H4R Low Alloy Stick Electrodes (4.54kg)

ESAB AtomArc T: The Standard for T-1 Steel Fabrication

ESAB AtomArc T 3/32" Stick Electrodes represent the pinnacle of low-hydrogen, low-alloy welding technology, specifically formulated for joining T-1 steels. Carrying the AWS classification E11018M H4R, these electrodes are engineered to deliver tensile strengths ranging from 112 to 115 ksi, ensuring that the weld metal matches the high-performance characteristics of the base material. This product is the go-to solution for professional welders involved in heavy-duty fabrication where structural integrity is paramount.

The metallurgy of AtomArc T is designed to provide exceptional toughness and ductility. It is particularly noted for its high-strength welds that maintain excellent impact properties at low temperatures. This makes the electrode suitable for a wide array of critical applications, including bridge construction, civil engineering projects, and the manufacturing of railcars and barges. The electrode's ability to maintain its mechanical properties in both the as-welded and stress-relieved conditions offers significant flexibility in welding procedures and post-weld heat treatment cycles.

Technical Superiority and Reliability

Reliability in welding consumables is defined by consistency and protection against environmental factors. The AtomArc T features an advanced moisture-resistant coating (H4R), which drastically reduces the risk of hydrogen cracking—a common challenge when welding high-strength low-alloy (HSLA) steels. To further guarantee performance, ESAB packages these electrodes in hermetically sealed steel cartons. This packaging strategy ensures that the low-hydrogen characteristics are preserved during storage and transport, allowing for immediate use without the need for initial re-baking in many scenarios.

Operating within an optimal amperage range of 70-100 Amps, the 3/32" diameter allows for precise manipulation of the weld puddle, suitable for all-position welding. The slag system is designed for easy removal, and the arc characteristics are smooth and stable, reducing spatter and cleanup time. For fabrication requiring 100% joint efficiency on T-1 and similar high-yield steels, ESAB AtomArc T is the definitive choice.
