Welding and other related technologies are used in manufacture of space vehicles. When developing the designs of third generation rockets, special attention is paid to problems of improvement of flight reliability and safety characteristics that is ensured by rational application of new types of high-performance welded joints in the design, which are produced due to introduction of effective welding processes. Fabrication of the traditional (waffle) structure and advanced (stringer) structure was analyzed, taking into account the cost-effectiveness of application of the welding processes. In terms of cost-effectiveness, it is rational to apply friction stir welding. Here, a considerable economic effect of application of friction stir welding technology for fabrication of structures of fuel tanks of rocket carriers is anticipated. 10 Ref., 7 Tabl., 11 Fig.
