FIELD: electrode welding, in particular, compositions of coatings of welding electrodes for welding of low-carbon, medium-carbon and low-alloyed steels. SUBSTANCE: coating contains the following components, mas.% : SiO<SB>2</SB>10-40; TiO<SB>2</SB>6-20; CaCO<SB>3</SB>10-30; FeO and/or Fe<SB>2</SB>O<SB>3</SB>10-20; Mn5-15; C1-3; H<SB>2</SB>O 0,2-6; Na<SB>2</SB>O and/or K<SB>2</SB>O1-10;; Fe, the balance. EFFECT: enhanced impact strength of metal built up by electrode. 1 tbl
