METHOD FOR REPAIR OF A TURBO MACHINE BLOCKED WITH A BLADES, TURBO MACHINE, AND AN EXPERIENCED SAMPLE FOR IMPLEMENTING THE INDICATED METHOD

摘要

The procedure consists of first machining the damaged turbine blade (2) to prepare it for receiving a repair piece by cutting off a standard section (9) along a line (10). The repair piece is then attached to a test blade by an electron beam welding machine with pre-set operating parameters. After the qualities of the repair piece have been verified it is welded onto the prepared turbine blade repair zone using the same machine and operating parameters.
