Abstract
Provided is a novel method for improving fatigue strength, which is applicable to any small portion that is covered with another member. A method for improving fatigue strength according to the present invention includes: disposing an aid (3, 15) to be opposed to an processing object (2A, 2B, 6) on which a fatigue strength improving process is performed, the aid being configured to assist the improving process; and generating sparks between the aid (3, 15) and the processing object (2A, 2B, 6).
Claims15
A method for repairing cracks on an inner peripheral surface of a processing object which comprises first and second splice plates, the method comprising:
- overlapping the first splice plate on the second splice plate, wherein said inner peripheral surface defines a through hole passing through said first and second splice plates;
- fastening said first and second splice plates together by disposing a fastener to the inner peripheral surface;
- and
- generating sparks between the inner peripheral surface and the fastener, thereby repairing said cracks on the inner peripheral surface.
