Low alloy copper-coated solid wire designed for welding low alloy steels with 2% Ni content, fine grained for low temperature applications. Suitable for the construction of offshore platforms, tanks and pipelines, where good fracture toughness from as-welded joints is demanded down to temperatures in the region of -60°C. To be used under the shield of Ar+CO2.
