Copper-plated solid silicon-manganese wire is designed for welding non-alloy steels, for load-bearing metal structures, pressure vessels and shipbuilding steels with a minimum tensile strength of up to 500 MPa, as well as low-alloy carbon-manganese steels with a yield strength of up to 400 MPa. Welding can be carried out both in Ar/20CO2 welding arg mixture and in pure CO2. Suitable for high current welding.
