Abstract
A coating for protecting steel from corrosion is a mixture of an organic solvent and binder, powdered magnesium, and a passivating agent which has a pH greater than about 8 when in contact with water. Steel covered with the coating is cut or welded by the application of heat sufficient to melt the magnesium and underlying steel. In some embodiments, the pyrolysis products of the coating create an odor which warns of the build-up of nitrogen oxides produced by typical welding and coating operations.
