S6332 - ER70S-6 Mild Steel TIG Welding Rod - 2.5mm (3/32") - 10lb Tube

High-Quality ER70S-6 Mild Steel TIG Rods

The ER70S-6 TIG Welding Rod is a premium mild steel filler metal designed for the Gas Tungsten Arc Welding (GTAW) process. This 2.5mm (approximately 3/32") diameter rod is formulated with higher levels of manganese and silicon compared to standard ER70S-2 or ER70S-3 wires. These added deoxidizers act as powerful cleaning agents during the welding process, scavenging impurities and allowing for sound, porosity-free welds even when the base material exhibits light rust, mill scale, or oil. This makes the S6 classification the industry standard for general fabrication where surface preparation may not always be perfect.

Manufactured to meet AWS A5.18 and ASME SFA 5.18 standards, this rod provides a minimum tensile strength of 70,000 psi, ensuring structural integrity for critical applications. The rod features a high-quality copper coating which serves a dual purpose: it protects the filler metal from oxidation during storage and enhances electrical conductivity for a stable, consistent arc. Packaged in a durable 10lb tube, these 36-inch cut lengths are protected from moisture and contaminants, ensuring they arrive ready for high-performance welding.

This filler metal is suitable for both single-pass and multi-pass welding applications. It exhibits excellent wetting characteristics, resulting in a flat weld bead with smooth tie-ins, reducing the need for post-weld grinding. It is widely used in pipe welding, automotive fabrication, structural steel erection, and general maintenance and repair operations.
