Friction Welding - A “Natural” for Production

Friction welded assemblies of various sizes, shapes, and material combinations are described and the basic friction welding cycle parameters are tabulated. Photomicrographs of typical welds are shown. Work-piece size, shape, and material properties greatly influence welding parameters, although excellent friction welds can be achieved in all cases. It is shown that the necessity for rotating at least one work piece to develop the frictional heat does not limit the usefulness of the process.
