Abstract: Methods of non-destructive testing of metal steam turbine rotors, currently used are inefficient for detecting defects at an early stage of their development. There for becoming urgent task of improving methods of non-destructive testing to assess the state of the metal. Article describes the basic parameters that must be measured to predict the state of the diagnostic objects, traditional methods of non-destructive testing to identify defects and detection of internal faults in the metal turbines. Also the article contains examples of the most modern methods and diagnostic tools based on the identification of "pre defective" condition of the metal long working equipment. We can confidently say that we need a shift from traditional defectoscopy to technical diagnostics metal steam turbine rotors using new methods and control.

Key words: steam turbine rotor nondestructive testing pre defective condition prediction of the state
