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): PA0 calcined magnesite: 4-8, PA0 feldspar: 6-9, PA0 calcium fluoride: 4-5.5, PA0 titanium dioxide: 14-20, PA0 ferromanganese: 6-10, PA0 ferrosilicon: 1.5-3, PA0 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.
