Abstract

An arc welding electrode is made by extruding a coating composition about a wire, tube or solid rod of iron or steel, the composition comprising a minor proportion, preferably 2-10% by weight of the composition, of an inorganic constituent having a melting point between 150 DEG C. and 600 DEG C., e.g. boric oxide or chromium trioxide. Specific flux coating compositions given are .1).Calcium carbonate.18% ..Titanium dioxide.14% ..Felspar.12% ..Iron powder.36% ..Ferromanganese.11% ..Boric acid (H3BO3).9% .2).Felspar.60% ..Calcium oxide.20% ..Chromite ore.10% ..Silicon.5% ..Chromium trioxide.5% .and.. .3).CaCO3.40% ..CaF2.24% ..FeTi (25% Ti).10% ..FeNb.20% ..CrO3.6% wherein all proportions are by weight. The electrode may have portions coated with dissimilar compositions, e.g. as coaxial layers, possibly extruded simultaneously. The compositions may also contain copper oxide.
