HYW ER70S-2 TIG Welding Rod — 2 lb is a premium triple-deoxidized solid carbon-steel filler rod in 36-inch cut lengths, supplied in a convenient 2 lb tube. Containing zirconium, titanium, and aluminum deoxidizers, it produces exceptionally clean, porosity-free welds even over rust and mill scale — the preferred filler for high-quality root passes on pipe and out-of-position GTAW.
Key Features
- › Triple-deoxidized (Zr, Ti, Al) for superior, porosity-free welds
- › Excellent over rust, mill scale, and less-than-clean base metal
- › Premium choice for X-ray quality pipe root passes
- › Bright, controllable puddle for precise out-of-position welds
- › Copper-coated, straightened 36" rods supplied in a 2 lb tube
Ideal Applications
- › Pipe and tube root passes (X-ray quality)
- › Pressure vessels and code-governed fabrication
- › Out-of-position GTAW on carbon and low-alloy steel
- › Maintenance, repair, and field welding
- › General precision mild-steel TIG welding
