255115321 - ESAB Atom Arc T E11018-M Welding Rods 5/32 Inch

The Welder's Choice for High-Tensile Steel

When the job calls for welding 100,000 psi yield strength steels, you need a rod that doesn't just meet the spec but runs smoothly enough to pass X-ray every time. The ESAB Atom Arc T (E11018-M) is legendary among professional welders for its exceptional operator appeal and metallurgical superiority. Unlike standard 7018 rods, this electrode is alloyed to provide a minimum tensile strength of 110,000 psi, making it the specific match for T-1 (A514) and similar Q&T steels found in heavy mining and construction equipment.

The "M" in E11018-M stands for military-grade performance, originally developed to meet the toughness requirements of submarine hulls. For the welder, this translates to a puddle that wets out smoothly at the toes, reducing stress concentrations and the risk of undercut. The iron powder coating increases deposition efficiency, helping you fill joints faster without sacrificing quality. It runs on DCEP (Reverse Polarity) and offers a crisp, forceful arc that penetrates well but remains manageable in out-of-position welds. The slag system is designed to release easily, often curling up by itself as the weld cools, which saves you valuable grinding time.

Moisture control is critical when welding high-strength low-alloy (HSLA) steels. The Atom Arc T features an advanced H4R moisture-resistant coating that resists picking up atmospheric humidity even during long shifts. This low-hydrogen characteristic is vital for preventing underbead cracking and ensuring the weld metal retains its ductility and impact toughness, even at sub-zero temperatures. Whether you are repairing a cracked excavator bucket in the field or fabricating a pressure vessel in the shop, Atom Arc T gives you the confidence that your welds will hold up under extreme stress.
