Abstract

On the basis of the extensive base of experimental research results there are defined standard stress-strain properties of welded butt-joints of aluminum alloys thermally non-hardened with Al-Mg system. It is shown that during friction welding with stir there is a formation of a gradient structure with ultra-fine grain in the stir area. It is defined that at the heart of the mechanism of a joint formation are placed phenomena of plastic deformation of a displacement and turn of structural elements. There is defined a range of optimum proportions expressing a length of a tool linear displacement along a joint during one its turn in which a qualitative formation of thin sheet joints of the Al-Mg system.
