AWS A 5.28: ER80S-G ER80S-G is a Low-alloy copper-coated solid wire with Ni-Cu-Cr additions designed for weather-resistant steel. Thanks to the chemical composition and weld metal mechanical properties it is also used for welding high tensile strength steels. Suitable for the construction of containers, tanks, bridges, building panels, chimneys, means of transport, offshore platforms, etc. The weld material shows a good resistance to atmospheric corrosion and salt water. To be used under the shield of Ar+CO2.
