Abstract

A coated welding electrode has a stainless-steel core of the composition : chromium 17-20, nickel 8-10, manganese 1-3, silicon 0-3, carbon 0.05-0.3 per cent; iron and impurities balance, with a coating thereon of the composition : calcium fluoride 5-7.5, calcium carbonate 7.5-12.5, titanium dioxide 20-25, calcium silicate 5-7.5, chromium metal powder 35-45, ferro silicon alloy 5-10 parts by weight, with or without a binder, e.g. starch, alkali metal or silicate. The core may contain molybdenum titanium and columbium totalling less than 1 per cent. An example of an electrode has a core of the composition : chromium 19, nickel 9, manganese 2, carbon 0.15 per cent; iron and impurities balance with a coating of the composition: calcium fluoride 6, calcium carbonate 10, titanium dioxide 23, calcium silicate 6, chromium metal powder 40, ferro silicon alloy 7 parts by weight. Sodium silicate solution was added to make a paste.
