Definitions
- FIG. 1 is a longitudinal sectional view schematically showing a repair state of a rotor by a repair method according to a first embodiment of the present invention.
- FIG. 1 is a longitudinal sectional view schematically showing a rotor repaired state by the repairing method according to the first embodiment of the present invention.
- FIG. 1 is a longitudinal sectional view schematically showing a rotor repaired state by the repairing method according to the first embodiment of the present invention.
- a flux having electrical conductivity for example, a flux PFH-203 manufactured by Kobe Steel, Ltd. is suitable.
- overlay welding by TIG welding is performed from the first layer to a height of 7 mm or more, and thereafter, overlay welding is performed on the remaining portions by the welding method of the first embodiment.
- the height of 7 mm or more is a height at which the heat affected range by the submerged arc welding of the first embodiment does not reach the weld heat affected zone A.
- the welding speed of TIG welding is about 10 g / min.
- FIG. 5 is a vertical cross-sectional view schematically showing a state near a blade groove before repair in an outer peripheral portion of an example of a rotor.
- the figure shows a type with blade grooves cut in a direction perpendicular to the rotor axis.
- a defect b has occurred in, for example, a corner of the blade groove 103 provided on the outer peripheral portion of the rotor body 101.
- the entire outer peripheral portion of the rotor body 101 indicated by the repair range B is removed.
- FIG. 8 is a diagram schematically showing a state in which the rotor body during overlay welding is viewed from the outside, and shows a shift procedure of the weld bead.
- the welding bead is run in the welding direction indicated by the arrow while rotating the rotor body 101 between the copper walls 104, and a predetermined welding pitch P
- the layers are stacked in numerical order while shifting. Each circumference has a predetermined overlap range Q.
- FIG. 9 is a cross-sectional view schematically showing a welding position during rotor repair.
