Abstract
Comparative analysis of the degree of softening and level of strength of welded joints of ductile low-alloyed aluminium alloys and high-strength complex-alloyed aluminium alloys produced by friction stir and non-consumable electrode welding has been performed. It is shown that the strength of welded joints of ductile low alloys is the same with both welding processes. Deformation strengthening of welds of high-strength complex aluminium alloys achieved in friction welding provides a higher level of their strength in fusion welding.
