COMPOSITION OF ELECTRODE COATING Russian patent published in 2000 - IPC

FIELD: welding, namely compositions of coating of electrodes for welding low-carbon and low-alloy steels. SUBSTANCE: composition includes rare earth metal carbonate (marbor, dolomite), silicate (talc, phlogopite, muscovite), ferrotitanium, ferromanganese, carbon containing ferromanganese, ingredient containing titanium dioxide (ilmenite, rutile). Composition contains normalized relations of ferromanganese and carbon containing ferromanganese and also ferrotitanium and carbon containing ferromanganese; total quantity of deoxidizers in range (20-35)%. EFFECT: enhanced mechanical properties of welded metal, improved efficiency of using manganese at keeping high technological characteristics of rutile type electrodes. 5 cl, 1 tbl
