Method of repairing a blade of an integrally bladed turbine rotor disc and test-piece for carrying out the method
摘要
<p>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.</p>
