Comprehensive approach to weld repair on elements of power transmission – case study for hydro turbine shaft
Апстракт
Turbine and generator rotors and shafts undergo highstresses during regular working life and, from a safetyand operational aspect, are the most significantcomponents of a power generation system. Dependingon the appropriate operating conditions, like temperatureand/or corrosion the, shafts can be fabricated out oflow/high alloy heat resistance material or of low alloyed,highly toughened material for different application.Despite known good practice and developed operationprocedures, the failures of shafts sometimes occurs. Theright and well defined failure analysis is the basis forfeasibility analysis of repair method in the powergenerating industry. The analysis of direct and indirectcosts of repair after the failure analysis as well as theanalysis of the repair and post-repair conditions of therepaired element is the vital for decision on the keyquestion. Is it possible to repair this element and what isthe optimal repair strategy?This paper compares and analyses two approaches,by we...ldability analysis and weld cycle simulation, inorder to determine welding feasibility analysis ofcracked hydro turbine shafts.
