Peculiarities of different types of friction welding of copper to aluminium, such as conventional, inertia and combined welding, are considered. Factors affecting formation of welded joints are analysed on the basis of experimental data. Conditions which determine formation and growth of the intermetallic interlayer in the joining zone are considered. Principles of control of the welding process to provide sound joints have been developed
Keywords: conventional friction welding, inertia friction welding, technology, dissimilar joints, heating and forging stages, process parameters, pressure, rotation speed, upsetting, time of heating and deceleration, equipment, intermetallic interlayer, quality of a joint
