ELECTRODE COATING FOR UNDERWATER WET WELDING OF HIGH-ALLOY STEELS 10/18

摘要

An electrode coating for underwater wet welding of high chromium-nickel steels 10/18 comprises marble, fluorspar, manganese, ferroniobium, titanium dioxide. The coating composition additionally comprises metal chromium and nickel powder, deoxidizers - ferrotitanium and ferrosilicon (taken together or separately), plasticizing agents. The ratio of fluorspar to marble CaF/CaCOis 2.0-3.0.
