EX100S1000062TL00 - Exocor ER100S-1 High Strength TIG Rod 1/16" - 10lb Tube

High-Performance ER100S-1 TIG Welding Rods

The Exocor ER100S-1 TIG Rod is a premium low-alloy steel filler metal designed specifically for the welding of high-yield strength steels. Engineered to meet the rigorous demands of heavy industrial and military applications, this rod delivers a minimum tensile strength of 100,000 psi (100 ksi). It is the ideal choice for fabricators working with quenched and tempered steels such as HY-80, HY-100, and ASTM A514 (commonly known as T-1 steel). The 1/16-inch (1.6mm) diameter allows for precise control over the weld pool, making it suitable for root passes and thin-wall tubing in critical structures.

This filler metal is characterized by its excellent impact toughness, even at low temperatures, ensuring the integrity of welds in harsh operating environments. The chemical composition typically includes additions of manganese, silicon, nickel, and molybdenum, which work together to refine the grain structure and enhance mechanical properties. When used with 100% Argon shielding gas, the ER100S-1 produces clean, sound deposits that are often of X-ray quality, reducing the need for extensive post-weld rework.

Proper storage and handling are essential for low-alloy wires to prevent hydrogen-induced cracking, and this product comes in a sealed 10 lb tube to maintain freshness and prevent contamination. Fabricators should note that preheat and interpass temperature controls are often critical when welding high-strength base materials to prevent cracking in the heat-affected zone. The Exocor ER100S-1 provides the consistency and reliability required for pressure vessels, crane manufacturing, and heavy earthmoving equipment.
