Low alloy copper-coated solid wire designed for welding low alloy steels with 1% Ni content, fine grained for low temperature applications (-50°C). Nickel increases atmospheric weathering resistance and improves electrochemical balance between weld and base metal. Suitable for the construction of offshore platforms, pressure vessels and pipelines. To be used under the shield of Ar+CO2.
