FIELD: process engineering.
SUBSTANCE: proposed structural element may be used in aircraft structure, as, for example, wing spar including web and one or several stringers adjoining said web. At least first and second metal blocks are used. Note here that ultimate strength in compression of first block exceeds that of second block. First metal block is machined to produce first solid part comprising first section of web and at least one element of stringer. Second metal block is moulded to produce second part that comprises second section of web. Produced parts are assembled by arranging web parts so that their faces fit over entire length and stringer part fits second section of web. Parts are welded, preferably jointed by friction welding with mixing.
EFFECT: production of bi- and multi-unction structural elements.
