G 46 5 M21 3Ni1

Low alloy copper-coated solid wire designed for welding low alloy steels with 1% Ni content and fine grained steels for low temperature applications (−50 °C). Nickel increases atmospheric weathering resistance and improves the 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.
