ELECTRODE COATING COMPOSITION Russian patent published in 2004 - IPC

Abstract RU 2225783 C2

FIELD: manufacture of electrodes for manual electric arc welding. SUBSTANCE: coating of electrode contains, mass%: wollastonite, 44 - 45; marbor. 15 - 17; ferromanganese, 14 - 15; ferrosilicon, 4 - 5; talc, 20 - 22. Using of low-cost easy-to-produce raw material as main components allows to keep high mechanical properties of metal joint. EFFECT: enhanced quality of electrode due to improved coating composition. 3 tbl
