Friction welding with stirring of aluminium alloys

摘要

Considered are main principles of realisation of a new method for friction stir welding (FSW), allowing production of various joints in sheet billets. Designs of the tools for realisation of FSW, peculiarities of formation of the joints in different aluminium alloys, their properties and structure, application fields for FSW, equipment for FSW of various structures, quality control methods and methods for elimination of specific defects are described.
