Abstract
Example embodiments of the present subject matter relate to methods, systems, and a computer program product for performing assisted ultrasonic inspection flaw screening. The method includes analyzing a plurality of ultrasonic responses having scan axis and ultrasound axis positions. For a plurality of respective scan axis-ultrasound axis positions, an ultrasonic response representative of ultrasonic responses for the scan axis-ultrasound axis position is selected. The selected ultrasonic responses then may be associated for ultrasonic inspection flaw screening.
Claims15
A method of ultrasonic inspection flaw screening for weld inspection, comprising:
- receiving scan data corresponding to different beam angles for different scan axis and ultrasound axis positions of an object including a weld, including a plurality of ultrasonic responses for each of a plurality of intersecting scan axis-ultrasound axis positions, wherein the scan axis is parallel to a long axis of a weld line of the weld;
- for each of the plurality of intersecting scan axis-ultrasound axis positions, selecting a representative ultrasonic response with a maximum amplitude value from the plurality of ultrasonic responses for the respective scan axis-ultrasound axis position based on amplitude values of the plurality of ultrasonic responses;
- merging selected ultrasonic responses for the plurality of intersecting scan axis-ultrasound axis positions to generate an image for weld inspection;
- detecting a drift in a geometry of the weld in the image;
- and
- straightening the merged ultrasonic responses to reduce or remove the drift in the image.
A system comprising:
- one or more processors of a machine;
- and
- a memory storing instructions that, when executed by the one or more processors, cause the machine to perform operations comprising:
- receiving scan data corresponding to different beam angles for different scan axis and ultrasound axis positions of an object including a weld, including a plurality of ultrasonic responses for each of a plurality of intersecting scan axis-ultrasound axis positions, wherein the scan axis is parallel to a long axis of a weld line of the weld;
- for each of the plurality of intersecting scan axis-ultrasound axis positions, selecting a representative ultrasonic response with a maximum amplitude value from the plurality of ultrasonic responses for the respective scan axis-ultrasound axis position based on amplitude values of the plurality of ultrasonic responses;
- merging selected ultrasonic responses for the plurality of intersecting scan axis-ultrasound axis positions to generate an image for weld inspection;
- detecting a drift in a geometry of the weld in the image;
- and
- straightening the merged ultrasonic responses to reduce or remove the drift in the image.
A non-transitory machine readable storage medium that, when executed by a machine, cause the machine to perform operations comprising:

- for each of the plurality of intersecting scan axis-ultrasound axis positions, selecting a representative ultrasonic response with a maximum amplitude value from the plurality of ultrasonic responses for the respective scan axis-ultrasound axis position based on amplitude values of the plurality of ultrasonic responses;
- merging selected ultrasonic responses for the plurality of intersecting scan axis-ultrasound axis positions to generate an image for weld inspection;
- detecting a drift in a geometry of the weld in the image;
- and
- straightening the merged ultrasonic responses to reduce or remove the drift in the image.
