August 13, 2020, Rybinsk. – At UEC-Saturn PJSC (part of the United Engine Corporation, a Rostec State Corporation company) a unique technology of the gas turbine engine outlet guide vanes electron-beam welding has been developed.
Chief Welder Department specialists together with Shop 57 employees developed and put in place the technology of the gas turbine engine outlet guide vanes (made of titanium alloy VT-6) electron-beam welding.
The feature of the new technology is the fact that electron-beam welding of the OGV vanes is done by a special weld seam with a temper bead formation from the side of the OGV flowpath.
For establishment of this technology it was needed to perform development works on selection of the electron-beam welding mode which ensures consistency of the temper bead formation in welded materials with thickness 4,0 and 16,0 mm. Special tooling for assembly, electron-beam welding and heat treatment of the part was designed.
The specially developed tooling for electron-beam welding provides protection of the part flowpath from welding spatters and transcanal electron beam generated during welding with temper bead formation.
Welding equipment has been retrofitted for introduction of this technology: a long rack for electron-beam gun fixation has been developed; it gives an opportunity to put it into the inner ring of the part and to weld vanes along the closed path inside in a full program mode.
This technology was established already at the stage of the part designing. The process of preparation to the technology introduction together with the manufacturing of the required tooling took about half a year. Designers, and process engineers, and specialists of the Chief Welder Department, and Shop 57 employees were working together on the development and introduction of the unique technology, they mastered welding modes and technological sequence of operations performance, they accompanied the whole process of the part production: from assembly and welding up to special types of inspection and geometry measurement. “Development and introduction of the unique technology of the gas turbine engine outlet guide vanes electron-beam welding at the enterprise,
- said Alexey Polyakov, UEC-Saturn PJSC Chief Welder, - gave an opportunity to manufacture the parts with minimum labor intensity and minimum costs for industrialization without application of the technology of manual argon-arc welding in manned chamber as well as of the investment casting technology.”
Currently two OGVs for aircraft gas turbine engines are manufactured with the new technology of electron-beam welding.
