TTU936 - ER70S-2 Mild Steel TIG Rod 1.6mm (1/16") - 1lb Tube

Premium ER70S-2 Mild Steel TIG Welding Rods

The ER70S-2 Mild Steel TIG Rod in 1.6mm (1/16") diameter is a premium filler metal designed for the Gas Tungsten Arc Welding (GTAW) process. This product is formulated with a triple-deoxidized chemistry containing Zirconium, Titanium, and Aluminum, in addition to the standard Silicon and Manganese found in other mild steel wires. This unique composition makes ER70S-2 the preferred choice for welding on surfaces that are not perfectly clean, providing superior resistance to porosity caused by rust, mill scale, oil, or dirt.

Engineered for critical applications, this rod produces high-quality, defect-free weld deposits with excellent ductility and impact strength. It is widely used in pipe welding, pressure vessel fabrication, and maintenance repair operations where base metal preparation may be difficult. The 1.6mm diameter offers excellent versatility, suitable for root passes on pipe as well as general fabrication of thin-walled tubing and sheet metal. Packaged in a durable 1lb tube, this product ensures your filler metal remains straight, clean, and ready for use, minimizing waste for smaller projects or specialized repairs.
