ER70S-G Welding Wire (CHW-50C8)

ER70S-G welding wire is used for welding structures fabricated by equivalent tensile strength carbon steels or low alloy steels of X60, X65, 18Nb, 12-16Mn, etc. such as engineering & construction machineries, pipelines, ships, equipments for petrochemical industry, high pressure vessels, lifts, vehicles, bridges, skyscrapers and so on. Excellent mechanical properties of weld metal can be obtained due to strictly control the S, P and a few Ti is added into the wire. It can be operated under high current.
