Abstract
A method of indicating a position of a flaw in a part including holding a probe by hand in contact with a surface of the part with a probe; detecting a flaw in the part by emitting ultrasound from the probe into the surface of the part and detecting echoes of the ultrasound from the flaw; providing an indicator on the surface of the part indicating a detection position of the probe; after the indicator has been provided, removing the probe by hand from the surface of the part, leaving the indicator in place; and after the probe has been removed from the surface of the part, providing a flaw marker on the surface of the part indicating an estimated position of the flaw.
Claims16
A method of indicating a position of a flaw in a part, comprising:
- holding a probe by hand in contact with a surface of the part with a probe;
- detecting a flaw in the part by emitting ultrasound from the probe into the surface of the part and detecting echoes of the ultrasound from the flaw;
- providing an indicator on the surface of the part indicating a detection position of the probe;
- after the indicator has been provided, removing the probe by hand from the surface of the part, leaving the indicator in place;
- and
- after the probe has been removed from the surface of the part, providing a flaw marker on the surface of the part indicating an estimated position of the flaw, wherein the flaw marker is spaced from the indicator and a position of the flaw marker is based on a position of the indicator;
- wherein the indicator comprises material deposited on the surface of the part at the detection position by a probe-mounted marking device which is mounted to the probe, or the indicator is a light indicator provided by a beam of light which illuminates the surface of the part at the detection position.
A testing apparatus, comprising:
- a probe configured to contact a surface of a part, the probe comprising a wedge and an ultrasonic transducer mounted to the wedge;
- and a probe-mounted marking device mounted to the probe, wherein the probe-mounted marking device is configured to provide an indicator on the surface of the part indicating a detection position of the probe by depositing material on the surface of a part.
A testing apparatus, comprising:
- a probe configured to contact a surface of a part, the probe comprising a wedge and an ultrasonic transducer mounted to the wedge;
- and a light source configured to provide a light indicator on the surface of the part indicating a detection position of the probe by illuminating the surface of the part at the detection position with a beam of light, wherein the probe can be moved relative to the light source so that the probe can be removed from the surface of the part, leaving the light indicator in place.
