FIELD: fusion welding, namely compositions of coatings of electrodes for manual electric arc welding of constructions of carbon and low-alloy steels. SUBSTANCE: electrode coating includes next ingredients (mass%): ilmenite concentrate - (40-45); ferromanganese - (15-20); feldspar - (16-22); cellulose - (1-2); dolomite - (10-18); muscovite shale - (15-12). EFFECT: enhanced plastic properties of covering mass, improved strength of ready electrode coating, easy separation of slag scum, high mechanical properties of welded joint. 2 tbl
