The directions of modernization of welded structures, previously created and serially produced in the aerospace, transport and other industries, are considered. For this, it is proposed to use thermally hardened aluminum alloys as the base metal, and to obtain permanent joints, instead of argon-arc welding, use friction stir welding (FSW), which is performed in the solid phase and has many advantages. Purpose of the work: to show the usefulness of constructive and technological modernization of previously designed and manufactured structures, taking into account the latest achievements in welding, in particular, when creating structures from aluminum alloys using FSW. An example of the modernization of an aircraft beam made of AMg6 aluminum alloy with the help of a FSW is given, which clearly demonstrates how the shape and geometry of the structure are interrelated with the technology of its manufacture.The presented structural and technological options for the modernization of the beam ensured: a decrease in welding stresses and deformations, an increase in the cyclic strength of a structure, savings in materials, labor, time and a decrease in the cost of manufactured products.
