Comparative analysis of the degree of weakening and level of strength of the 1.8 mm thick TIG- and FS-welded joints on dissimilar high-strength multi-component aluminum alloys AMg6M, 1420, 1201 and 1460 was carried out. Peculiarities of formation of the weld structure in both cases were studied. It is shown that strain hardening of the welds on high-strength multi-component aluminum alloys in friction stir welding provides their higher strength level, compared with that in fusion welding.
