Feasibility Analysis for Repair of Large Diameter Hydro Turbine Shaft Based on Weldability Test and Welding Cycle Simulation
Апстракт
Turbine and generator rotors and shafts undergo high stresses during regular working lifeand, from a safety and operational aspect, are the most significant components of a powergeneration system. Depending on the appropriate operating conditions, like temperature and/orcorrosion the, shafts can be fabricated out of low/high alloy heat resistance material or of lowalloyed, highly toughened material for different application. Despite known good practice anddeveloped operation procedures, the failures of shafts sometimes occur. The right and well-definedfailure analysis is the basis for feasibility analysis of repair method in the power generating industry.The analysis of direct and indirect costs of repair after the failure analysis as well as the analysis ofthe repair and post-repair conditions of the repaired element is the vital for decision on the keyquestion. Is it possible to repair this element and what is the optimal repair strategy?This paper compares and analyses two approache...s, by weldability analysis and weld cyclesimulation, in order to determine welding feasibility analysis of cracked hydro turbine shafts.
