Influence of heat treatment on the structure and properties weld laser welding superalloy EP693-ED, used in the production of GTE

In article is considered the process of creating a permanent welding connection of the superalloy HN68VMTYUK-VD (EP693-ED) on the basis of chromium-nickel, used in the manufacture of components and parts of gas turbine engine, with repetitively pulsed radiation on the CO2-complex TruLaserCELL 7020. The technology proposed for implementation in the production of parts and components of gas turbine engines for the purpose of improving the quality of welds by reducing high-temperature heating time by reducing the heat input. According to the results of electron microscopy, the physico-mechanical properties of the analyzed structure, formation and crystallization of the weld during welding CO2 laser.
