Often, turbine and generator rotors are produced from a single forging or from two forged bearing ends with a stack of discs in between. As with many other components in rotary equipment these precision machined forgings can be damaged or worm during operation. Due to the sensitivity of the material to any kind of heat treatment, including welding, repair of this damage presents a challenge for repair engineers.

This paper will give a general overview of repair. Repair may include welding, heat treatment, plasma spraying, shaft straightening, stress relieving, etc. Some recent repairs will be discussed.
