Description
A non-copper-coated solid wire designed for welding carbon and carbon-manganese steels with tensile strength up to 510 MPa. Suitable as well for welding thin, galvanised or electro-galvanised plates; very limited spattering thanks to the addition of titanium and zirconium. The fusion allows the degassing of zinc vapours, which prevents the formation of blows and pores in the weld bead. To be used under the shield of Ar+CO2.
