Theoretical and Experimental Research on the Reli-ability of Parts Rehabilitated by Arc Welding
Journal Title: Analele Universitatii "Eftimie Murgu" Resita. Fascicula de Inginerie - Year 2018, Vol 25, Issue 2
Abstract
The paper presents a technical-experimental study encountered in the repairs of the rotor blades to Kaplan turbines due to cavitation wear due to the cyclical stresses of the surfaces in contact. The repair of the Kaplan turbine rotor pallet was performed for the purpose of metal deposits to compensate for wear, to recover parts with cracks, cracks or bursts in the base material in order to reduce major costs associated with the operation and maintenance of the installations and equipment that make part of the production process.
