The Harris® ER70S-2 1/16" TIG Welding Rod is a high-performance carbon steel filler metal designed for critical welding applications where weld integrity and defect-free deposits are paramount. Packaged in a convenient 10 lb tube, this rod meets the rigorous AWS A5.18 ER70S-2 classification, making it a standard choice for industrial fabrication, pipe welding, and maintenance operations. The defining characteristic of the ER70S-2 alloy is its "triple deoxidized" chemistry. Unlike standard ER70S-3 or S-6 wires, this rod is fortified with specific additions of Zirconium, Titanium, and Aluminum, alongside Silicon and Manganese. This potent combination of deoxidizers aggressively scavenges oxygen and nitrogen from the weld pool, significantly reducing the risk of porosity and inclusions.
This metallurgical advantage makes the Harris ER70S-2 exceptionally capable when welding on base metals that are not perfectly clean. It excels in single-pass welding operations on surfaces exhibiting light rust, mill scale, or oil, where other rods might fail to produce a sound bead. Furthermore, it is the industry-preferred filler metal for root pass welding on carbon steel pipes, ensuring complete fusion and X-ray quality results. With a tensile strength of 78,000 psi and a yield strength of 60,000 psi, welds produced with this rod exhibit excellent mechanical properties suitable for structural steel, pressure vessels, and high-stress tubing.
The rod is engineered for use with Direct Current Straight Polarity (DCSP/DCEN), providing deep penetration and a stable arc characteristic of high-quality GTAW processes. The 36-inch cut lengths are industry standard, offering optimal handling for manual feeding. Whether used for small diameter pipe, tubing, or general sheet metal fabrication, the Harris ER70S-2 delivers consistent, high-quality results that professional welders and inspectors demand.
