COMPOSITION OF ELECTRODE COATING Russian patent published in 2000 - IPC

Abstract RU 2155656 C1

FIELD: welding, namely compositions of coating of electrodes for welding important structures of low-carbon low-alloy steels. SUBSTANCE: electrode coatings includes marbor, feldspar, quartz sand, ferrotitanium, carboxymetylcellulose, potash mica, ferrum powder. Ferrotitanium used as single alloying ingredient provides manganese content in welded on metal in range 0.35-0.45. Predetermined relation of quantities of feldspar and marbor allows to increase refining capability of generated slag and to decrease its oxidizing potential. EFFECT: enhanced plastic-viscous properties of welded seam metal. 1 tbl
