Abstract

170,343. Briscoe, H. V. A., Richardson, D., and District Chemical Co., Ltd. July 10, 1920. Fluxes.-A flux for the autogenous welding of aluminium comprises one or more alkali halides and an activating agent which reacts with them only in the presence of aluminium oxide. An alkali pyrosulphate or pyrophosphate is employed as activating-agent, a suitable mixture being potassium chloride 45 per cent, sodium chloride 30 per cent, potassium ' fluoride 7 per cent, lithium chloride 15 per cent, and the pyrosulphate or pyrophosphate 1 to 10 per cent. The materials are all melted together in a vessel free from metallic oxide soluble in the flux, and on solidifying a homogeneous mass remains, which is powdered.
