In today's aerospace industry there is a trend, which was probably started by economic factors, to donate more time and effort establishing viable salvage repairs of high priced items. This not only creates a competitive edge for the individual who initiates the repair but also stimulates industry to utilize other conceptions or improvements of existing techniques. This paper will deal with one such item which for some years was considered 'unrepairable' due to the complexity of its design. The compressor turbine vane ring in the PT6 Engine was selected because it is located in the heart of the engine. It is subjected to a very severe environment and damages occuring to it are a common problem in all gas turbine engines. Consequently this repair, which brings the part back to its new condition for a fraction of the replacement cost, involves a great deal of state of the art technology.
