Restoration of gas turbine engines is very urgent and at the same time difficult task, the solution of which provides significant cost savings. The work reflects the results of developing an efficient and reliable method for repairing gas turbine engine blades using electron beam welding. The technology of repair of three types of blade airfoil defects using welded-in pieces was mastered. It is shown that electron beam welding is ideal for solution of the problem of replacement individual elements of permanently assembled units of gas turbine engines. 4 Ref., 14 Figures.
