ESAB Dual Shield II 71 HI

The ESAB Dual Shield II 71 HI is a high-performance, all-position flux-cored wire designed for use with 100% CO2 shielding gas. With its low diffusible hydrogen content (less than 4 mL/100g), this wire ensures high-quality, crack-resistant welds, making it perfect for critical applications. It offers exceptional arc stability, low spatter, and excellent slag removal, enabling superior productivity in industries requiring high-impact strength, such as shipbuilding, structural steel fabrication, and heavy equipment manufacturing. This wire was designed to join low and medium carbon steels where higher impacts and toughness are required. Dual Shield II 71-HI has excellent welder appeal and performs well over steels with moderate rust and mill scale. The smooth metal transfer facilitates easy deposition of vertical – up stringer beads.

Classified under AWS A5.20 E71T-1C, the Dual Shield II 71 HI provides excellent mechanical properties, including high tensile strength and impact toughness, even at subzero temperatures. The wire’s versatility across a wide range of welding positions and parameters ensures consistent performance, whether welding vertically or overhead.
