Examples of modern lightweight structures from aluminium and its alloys are given. Their applications in different
mechanical engineering sectors are shown. The structure diversity reflects the technological capabilities and forms of
realization of unique properties of this material. Trends in world production and consumption of such structures have
been analyzed. it is noted that appearance of more advanced alloys with the respective set of physico-mechanical and
technological properties, as well as rational selection of the processes of their permanent joining, provide a high quality
of welds and welded structure reliability. Presented examples clearly illustrate the fact that the effectiveness of lightweight
structures is determined by functional requirements to products, weldability of the selected aluminium alloy and
level of its joining technology, provided the expenses and production time are minimum. 20 ref., 2 Tables, 6 Figures.
