Abstract

A method of preparing a moisture resistant coated low hydrogen welding electrode comprises applying to the surface of the electrode a moisture resistant basix flux and subsequently heat treating the coated electrode at a temperature within the range 520 DEG C. to 620 DEG C. wherein there is incorporated in the moisture resistant basic flux 10 to 25% by weight on the weight of the flux of an alkali metal silicate solution binder having an alkali metal silicate content of from 35% to 45% by weight on the weight of the solution and a molecular ratio of silica to alkali metal oxide in the alkali metl silicate within the range 2.9:1 to 3.9:1. The alkali metal silicate may be Na silicate and or K silicate. Fluxes are specified with their quantitative compositions which comprise limestone with various of the following: - fluorspar, rutile, Fe-Mn, Fe-Si, Fe-Ti, Fe-Mo, Fe-Cr, Fe-B, Fe-Nb, Si-Mn, Fe powder, Ni, Cr, zircon, felspar, clay and an organic pressing agent. Fluxes are specified which are suitable for electrodes to be used in welding of mild steel, low alloy high tensile creep resisting steel and austenitic steel.
