OVERVIEW

Premium ER80S-D2 TIG Rods for High-Strength Fabrication

Take your welding projects to the next level with Exocor ER80S-D2 TIG Welding Rods. This 1/8-inch filler metal is the go-to solution for welders working with high-strength steels who demand superior mechanical properties and weld quality. Unlike standard mild steel rods, the ER80S-D2 formula includes Molybdenum, Manganese, and Silicon, creating a powerful alloy capable of withstanding high stress and elevated temperatures.

Whether you are fabricating roll cages from 4130 chrome-moly tubing, repairing heavy equipment, or welding critical pipe sections, this rod delivers. The high silicon content acts as a rigorous deoxidizer, helping to pull impurities from the weld puddle and preventing porosity, resulting in clean, sound welds that pass radiographic inspection. The added molybdenum boosts the tensile strength to over 80,000 psi, ensuring your welds are as tough as the base material you are joining.

These rods come in a durable 10lb tube to protect them from moisture and contamination in the shop. The 36-inch length is standard for manual TIG applications, providing good reach and control. With Exocor's commitment to quality manufacturing, you can expect consistent diameter and surface finish, leading to a smooth, predictable arc and professional-looking results every time you strike an arc.

FAQ

ER80S-D2 contains Molybdenum and higher levels of Manganese, providing higher tensile strength (80 ksi vs 70 ksi) and better high-temperature properties compared to ER70S-2.

100% Argon is the standard shielding gas for TIG welding with ER80S-D2 rods.

Yes, ER80S-D2 is commonly used to weld AISI 4130 and 4140 steels, especially for applications like roll cages where heat treatment after welding may not be performed.

Yes, the high Manganese and Silicon content provides excellent deoxidation, making it more tolerant of mill scale and minor surface contaminants than some other rods, though cleaning is always recommended.

The weld deposit typically has a minimum tensile strength of 80,000 psi (80 ksi) as per AWS A5.28 specifications.

Preheat requirements depend on the base material thickness and grade (e.g., 4130 often requires preheat), not just the rod itself. Always consult the welding procedure specification.

DCEN (Direct Current Electrode Negative) is the standard polarity for TIG welding steel with this rod.

Store in a cool, dry place. Keep the tube closed when not in use to prevent moisture pickup and surface oxidation.
