Elevation of the Structural Strength of Welded Joints of Sheets Made of Alloys of the Al–Cu–Mg System

  • Published:
Materials Science Aims and scope

We study welded joints of 2 mm-thick sheets of D16T aluminum alloy (an analog of the 2024-T3 alloy used abroad), which is now not recommended for welding. The joints are obtained by the friction stir welding. It is shown that the complex structural strength parameter determined by the strength and cyclic crack-growth resistance of the weld metal of these joints is 2.4 times higher than for the base metal and 3.7–12 times higher than for the weld metal of D16 alloy joints obtained by using different technologies of welding and thermal treatment.
