ED034097 - Lincoln ER100S-1 High-Strength TIG Rod 3/32" (10lb Tube)

Lincoln Electric ER100S-1 TIG Rod Overview

The Lincoln Electric ER100S-1 is a premium low-alloy TIG welding rod designed for joining high-strength steels where weld integrity and mechanical performance are paramount. Engineered to meet AWS A5.28 specifications, this consumable produces welds with a minimum tensile strength of 100,000 psi (690 MPa), making it an ideal choice for fabricating structural components that must withstand significant stress and loading.

The chemical composition of this wire features a precise blend of low carbon, high manganese, nickel, and molybdenum. This specific alloying approach ensures that the weld metal not only achieves high yield and tensile strengths but also maintains excellent ductility and notch toughness, even at lower temperatures. It is specifically recommended for welding quenched and tempered steels such as HY-80, HSLA-80, and T-1 structural steels, often found in heavy equipment, crane manufacturing, and military defense applications.

Each 10-pound tube contains 36-inch cut lengths of 3/32" (2.4mm) diameter rod. The manufacturing process at Lincoln Electric ensures a clean wire surface, free from contaminants that could introduce porosity or inclusions into the weld pool. This attention to surface quality promotes a stable arc, smooth metal transfer, and a visually appealing bead profile. When used with 100% Argon shielding gas, the ER100S-1 delivers consistent X-ray quality welds required for critical infrastructure and pressure vessel fabrication.

Professionals selecting the ED034097 SKU can rely on Lincoln's metallurgical expertise to provide a filler metal that matches the base material's mechanical properties, reducing the risk of weld failure in high-stakes environments.
