ESAB offers Dual Shield Prime in four different compositions and diameters of 1.2 – 1.6 mm:
- Dual Shield Prime 71 H4:
For mild steel and 490N/mm2 class high tensile steel; uses Ar/CO2 shielding gas.
- Dual Shield Prime 71 LT H4
For mild steel and 490N/mm2 class high tensile steel for low temperature service; uses Ar/CO2 or 100% CO2
- Dual Shield Prime 81Ni1 H4
For mild steel, 490N/mm2 class high tensile steel and 550N/mm2 class high tensile for low temperature service; uses 100% CO2 shielding gas.
- Dual Shield Prime 81Ni1M H4
Designed to weld thick steel components and for impact toughness down to -60° C; uses Ar/CO2 shielding gas.
The Dual Sheild Prime family of seamless, low-hydrogen (H4) non-copper-coated flux cored wires features laser welded seams to combar moisture absorption in humid environments, delivering impact toughness down to -60º C.
Whether your job is in a shipyard, on an off-shore oil rig, or at a mining site, Dual Shield Prime Seamless Cored Wires were designed for use in the most critical welding applications.
No Copper Coating
Dual Shield Prime is a non-copper-coated wire. As a result, there are no copper flakes to contaminate wire feeders, liners, torches and contact tips with copper particles.
Low Diffusible Hydrogen Levels
Dual Shield Prime wires carry an H4 designation, indicating low levels of diffusible hydrogen in the deposited weld metal.
