METHOD OF REPAIRING CRACKS IN A METAL COMPONENT, IN PARTICULAR A TURBINE BLADE, AND TURBINE BLADES

摘要

The invention concerns a method of repairing cracks in a metal component (1), in particular a guide blade (10) of a gas turbine, said component (1) having a crack (2). According to the invention, the crack (2) in the component (1) is made into a groove (3), and at least one filler member (4) matching the shape of the groove (3) is inserted therein and rigidly connected to the component (1). Preferably, the groove (3) is formed by one or a plurality of straight segments (5) into each of which is introduced a rod-shaped filler member (4) corresponding to the component (1) from the metallurgical aspect. The invention further concerns a turbine blade (10), in particular a gas turbine guide blade, comprising a groove (3) filled with a filler member (4).
