FIELD: process engineering.
SUBSTANCE: invention relates to repair of turbo machine integral vaned disk. Vane repair is performed by method of electron-beam welding of insert. Vane repair begins from machining damaged zone to shape it as required. First sample piece is made. Second sample piece corresponding to insert is welded to first sample piece corresponding to insert and shaped as required to produce specimen for starting the work. Said specimen is checked for quality. Is quality complies with acceptance requirements, the insert is welded to zone to be repaired. Note here that the same electron-beam welding machine is used without changing its operating parametres. Now, repaired zone is again machined.
EFFECT: higher strength of vane.
