Abstract
Main advantages of weld formation in the solid phase as a result of plastic deformation of metal in friction stir welding of auminium alloys are considered. Examples of using this process in the developed countries to produce welded structures in various engineering sectors and the resulting saving of the resources are given. Structures, weakening degree, strength, values of resistance to off-center tension of samples, and levels of residual stresses and strains in high-strength aluminium alloy welded joints produced by friction stir welding and nonconsumable-electrode argon-arc welding are analyzed.
 
 
Keywords: high-temperature aluminium alloys, friction stir welding, nonconsumable-electrode argon-arc welding, microstructure, hardness, strength, off-center tension
