The formation of an oxide film on titanium during heat treatments often hampered subsequent welding or cold forming operations. A hot solution of sulfuric acid and calcium fluoride converts the scale to a gray film which can be readily removed by short immersions in a hot mineral acid bath, preferably a combination of 10% nitric acid with 2% hydrofluoric acid. The resulting surface is bright and smooth. This two-solution descaling method does not affect the welding and shaping characteristics of the metal. (J.S.R.)
