The invention relates to a lime-titania type covered electrode coating in the welding technical field, in particular to a covered electrode coating used for a nickel base material Inconel 690 in nuclear power equipment. The covered electrode coating comprises solid components of, by mass, 12-20% of marble, 6-10% of fluorite, 35-42% of artificial rutile, 2-4% of titanium dioxide, 2-5% of feldspar, 8-15% of manganese metal, 3-6% of ferrotitanium, 0-1% of soda, 0-1% of CMC, 1-3% of nickel powder, 5-8% of chromium metal and 5-8% of ferroniobium, and the powder of the components are evenly mixed to produce the covered electrode coating. By aid of the technical scheme, the problem of poor welding technology of the covered electrode caused by low melting point, large metal viscosity and the like of the nuclear power nickel base material is solved completely, and deposited metal of the covered electrode is provided with good mechanical properties.
