MINERAL ALLOY FOR COATINGS OF WELDING ELECTRODES AND CERAMIC FLUXES Russian patent published in 2005 - IPC

Abstract RU 2249498 C1

FIELD: manufacture of welding materials for electric arc welding of structures of carbon and low-alloy steels.

SUBSTANCE: mineral alloy contains next relation of ingredients, mass %: alumina, 45.0 -51.0; silica, 13.0 - 17.0; titanium dioxide, 3.0 - 4.0; calcium oxide, 10.0 - 16.0; calcium fluoride, 16.0 - 22.0. Composition of alloy prevents porosity of welded on metal due to lowered chemical activity of surface of alumina grains.

EFFECT: elimination of porosity of welded on metal.
