ESAB Atom Arc T Low Alloy Stick Electrodes - E11018M H4R

High-Strength Low-Hydrogen SMAW Electrodes for T-1 & High-Strength Steel

Atom Arc T was developed for welding T-1 steel in all applications. Mechanical properties of the welded joints equal or exceed the properties of the base steel in either the as welded or stress relieved condition, thus giving 100% design joint efficiency. In addition, Atom Arc T electrodes are suitable for many other applications, particularly where high-strength welds with excellent low temperature impact properties are required.

Key Features:

• Engineered for T-1 and similar alloys: Delivers welds with equal or greater mechanical properties than the base steel.

• Low-hydrogen iron powder coating: Reduces diffusible hydrogen for weld integrity in high-strength applications.

• Excellent impact toughness: Good performance at low temperatures.

• All-position welding: Suitable for flat, horizontal, vertical up, and overhead positions.

• AC/DC+ capable: Flexible power supply options for diverse shop setups.

• Hermetically sealed packaging: Keeps electrodes dry and ready to weld.
