Title: Flux-cored electrode for welding steels in carbon dioxide

Abstract: A flux-cored electrode intended for arc welding of steels in carbon dioxide s characterized in having a casing of a low-carbon steel filled with a powder flux containing (in weight percent): calcined magnesite: 4-8, feldspar: 6-9, calcium fluoride: 4-5.5, titanium dioxide: 14-20, ferromanganese: 6-10, ferrosilicon: 1.5-3, iron powder: the rest. The flux-cored electrode is practicable if used in semi-automatic and automatic welding of metal structures from structural low-carbon and low-alloy steels and from steels of improved strength. The flux-cored electrode with the above chemical composition of the flux is conducive to reduced separation of fluoride gases harmful to welders, the high welding characteristics of the electrode remaining intact.
