DEVICE AND METHOD FOR REPAIRING A ROTATABLE OBJECT

摘要

A device for repairing a rotatable object includes a controller that is selectively operable to send signals to a transducer. The transducer is selectively operable to cause movement of a sonotrode in response to the signals. The device is selectively operable in an ultrasonic welding mode and at least one of a deep rolling mode and an ultrasonic deep rolling mode. A method for repairing a rotatable object involves providing the device; positioning a repair substrate on at least a portion of a rotatable object contact surface of the rotatable object; operating the device in the ultrasonic welding mode to ultrasonically weld the repair substrate to the rotatable object contact surface; and operating the device in at least one of the deep rolling mode and the ultrasonic deep rolling mode to deep roll and/or ultrasonically deep roll the repair substrate to achieve a desired characteristic of the repair substrate.
