Abstract

PURPOSE: To easily repair a cast iron casing, by removing a repair portion of the cast iron casing being subject to damages, corrosion, etc., and by fitting a steel material plate to the portion and by fixing the plate.
CONSTITUTION: In a gas turbine casing 2, damage are particularly formed to corner portions at the air suction side 28a and the exhaust side 28b of a 4th stage stator blade groove 28 by the kinetic energy of working fluid. When repairing the damaged locations, the location of interrest is cut 30 as in a dotted line shape, and a blank fitting plate 18 in a steel material, which has a form obtained by mounting cutting allowance to a reconstruction dimension, is fitted at the location and clamping fastened by means of a clamping bolt 19. Then, the fitting plate 18 is worked according to the initial design value and reconstructed. Such a method can rapidly take the repair countermeasure of the casing without changing the accuracy of the original form.
