The Problem
Erosion caused by water particles occurs mostly at the last stages of rotor blades, increasing wear and tear and leading to a need of time-consuming replacement. This in turn causes longer downtime and more frequent replacement of worn blades. This directly affects the costs of power generation in the process of generating energy from water vapour.
The Results
With its unique infrastructure and competences, Plasma System was able to provide an effective solution based on laser technologies. This solution enables us to refurbish the crankpin using low-energy laser pad welding technology, which makes it possible to achieve maximum axiality without the risk of distortion of the finished component.
The component, after refurbishing and final machining of the crankpin, can practically be reinstalled directly into operation, without the need of any additional processing. The properties of the refurbished component are the same as the properties of a newly manufactured part.
