Welding analysis of turbine rotor

A research bachelor thesis analyzes possibilities of welding on turbine rotors with emphasis on efficiency, productivity and economy of welding procedure. The work evaluates presence of failures in weld joint and effort to prevent them. Characteristics of turbine materials, which resist to high service temperatures are presented on the literature sources basis. Concept of welded turbine rotor is preferred, because it has many advantages in using big steam turbines for power industry
