Welding technology of turbine rotors
 Pivoňka, Vít ; Kubíček, Jaroslav (referee) ; Daněk, Ladislav (advisor)
The paper deals with all the possibilities which can be used to weld the rotors of turbines, both the root and the filler welding. All these methods are thoroughly analyzed and their properties are described, especially the size of the heat input by welding of rotors of turbines. Further in this work is described the organization of the structure by means of a metallographic survey and a test of welds and materials, which are performed to check whether the material and the welding method are suitable for welding of rotors of turbines. In the experimental part are described all welds made by different welding parameters, one of these welds is chosen to achieve the best welding of the weld root. This weld is further investigated for hardness and change of microstructure after welding.
