Turbine and generator rotors and shafts undergo high
stresses during regular working life and, from a safety
and operational aspect, are the most significant
components of a power generation system. Depending
on the appropriate operating conditions, like temperature
and/or corrosion the, shafts can be fabricated out of
low/high alloy heat resistance material or of low alloyed,
highly toughened material for different application.
Despite known good practice and developed operation
procedures, the failures of shafts sometimes occurs. The
right and well defined failure 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 of the repair and post-repair conditions of the
repaired element is the vital for decision on the key
question. Is it possible to repair this element and what is
the optimal repair strategy?
This paper compar...es and analyses two approaches,
by weldability analysis and weld cycle simulation, in
order to determine welding feasibility analysis of
cracked hydro turbine shafts.
