FIELD: machine building.
SUBSTANCE: fuel injector includes the first component, the second component and the brazing alloy layer. First component has a side wall. Second component also has a sidewall. Hard brazing layer is made between side wall of first component and side wall of second component. Hard brazing alloy layer is formed from nickel (Ni) alloy for soldering, containing non-metallic components. Braze layer also has a section without a eutectic alloy, substantially consisting of non-metallic components diffused from the middle region between the first component and the second component. Invention also discloses a method for soldering a gas-turbine assembly section and a fuel injector version.
EFFECT: described is a fuel nozzle for a combustion chamber in a gas turbine assembly.
