Title:
DEFORMATION-CORRECTION METHOD FOR GAS-TURBINE COMPONENT
Document Type and Number:
Japanese Patent JP2009079495
Kind Code:
A
Abstract:
To achieve deformation correction with sufficient precision, and to reduce the occurrence of a defect which can happen during correction of the deformation.
A deformation correcting tool 3 includes a cone part 4 and a cylindrical part 5. The tool 3 is provided to a deformed part 2 in the inside of a combustor liner 1 in the direction for the cone 4 to come into contact. The deformation corrective tool 3 is moved in the axial direction of the combustor liner 1, and the outside of the combustor liner 1 is heated to correct the deformation.
