FIELD: manual electric arc welding of low-alloy steels. SUBSTANCE: electrode coating includes, mass%: ilmenite - rutile - zircon concentrate, 49 - 54; marbor, 12 - 18; talc, 10 -15; kaolin, 3 - 5; manganese containing component, 15 - 17.5; organic gas generator, 0.5 - 3.0. Ilmenite-rutile-zircon concentrate may be used as mixture of ilmenite, rutile and zircon taken in relation 1 : 0.5 : 0.25. Such coating allows to reduce melt metal splashing. EFFECT: improved stability of welding arc, lowered cost price of electrodes. 2 cl, 5 tbl
