COMPOSITION OF ELECTRODE COATING Russian patent published in 1995 - IPC

FIELD: welding materials. SUBSTANCE: electrode coating contains the following element in mass percentage: ilmenite rock - 26 to 36, marble - 11 to 15, ferromanganese - 15 to 20, ferrotitanium - 5 to 10, quartz sand 20 to 30, kaoline - 6 to 10, wood flour 1.5 to 2.0, soda ash 0.5 to 1.5. Wood flour shall be taken in the ratio 1:(4.0 to 5.0):(7.0 to 7.5). Ilmenite rock used in the coating composition is from the Aldan region and contains 8 to 15% of titanium oxide. Use of this electrode coating ensures mechanical properties of weld seam corresponding to seam type Э46. EFFECT: possibility of use for welding critical constructions manufactured of low-carbon steels. 3 tbl
