COMPOSITION FOR ELECTRODE COATING Russian patent published in 1994 - IPC

FIELD: welding. SUBSTANCE: coating includes carbonates, per cent by mass: carbonate 4-20, silicomanganese 13-25; mineral from group of silicates 15-39; hematite 26-50; organic gas former 2-6. Summary content of silicomanganese and hematite in coating should meet proportion 1: 2. Coating includes mica, talcum, nepheline or feldspar as mineral from group of silicates. EFFECT: high productivity in electrode surfacing, provision for welding in any spatial positions, high resistance of weld to ageing, saving of scarce rutile as it is not used in coating. 2 cl, 2 tbl
