  • Method for ultrasound scanning of a weld buildup
    Patent number: 10295501
    Abstract: A method for scanning a weld buildup formed on a circumferential portion of a disc for a steam turbine. The method includes providing an ultrasound probe for generating at least one ultrasound beam sweep. The circumferential portion is scanned with a first beam sweep oriented in a first beam orientation to detect a first flaw type in the weld buildup. The circumferential portion is also scanned with a second beam sweep oriented in a second beam orientation to detect a second flaw type in the weld buildup. Further, the circumferential portion is scanned with a third beam sweep oriented in a third beam orientation to detect a third flaw type in the weld buildup. The method also includes rotating the disc about a disc axis during scanning of the circumferential portion and moving the first, second and third beam sweeps in a direction parallel to the disc axis during scanning.
