摘要：
The basic problems that arise in the course of repairing the welded joints of high-temperature elements of heat-recovery boilers, manifolds, and steam pipelines of steam-gas power plants produced from heat-resistant T91/P91 chromium steels while in use are set forth. A review and analysis of repair technologies used abroad is presented. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.
