In this work, the quite possibly the main welding process explicitly the class of the solid-state welding process that is friction state welding process was discussed. Based on a base of experimental research results, the typical mechanical properties of butt-welded joints of thermally unhardened magnesium AZ31B and aluminum 7075 alloys are determined. The efficiency of the application of the friction stir welding to make fine microstructures from the given alloys operating under variable loads is substantiated.
