Review of the separate works of the E.O. Paton Electric Welding Institute on creation of advanced technologies of welding the equipment for the enterprises of the power engineering sector of Ukraine is presented. Approaches to producing welded rotor structures, combined joints of high-temperature components of equipment of heat power plants are described. The information on improvement of technology of welding thick-walled pipe elements from steel 10GN2MFA for NPPs is generalized. The gained experience forms the basis for solving new problems in the power engineering sector of the country. 12 Ref., 3 Tabl., 9 Fig.
