Abstract
review of some PWi works on creation of advanced technologies of welding the equipment for enterprises of power engineering sector of Ukraine is presented. approaches to producing welded rotor structures, and combined joints of high-temperature components of equipment of thermal power plants are described. information on improvement of the technology of welding thick-walled pipe elements from 10gN2MFa steel 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 Tables, 9 Figures.
Keywords: welding rotors, automatic submerged-arc welding, narrow gap, combined joints, manual arc welding, connection of steam generator with the main circulation pipeline, automatic argon-arc welding
