3 Terms and definitions
GB/T 12604.1 and GB/T 20737 and defined by the following terms and definitions apply to this document.
3.1
Angle error angularerror
The maximum number of shots received by the probe from the standard test block or the maximum back reflection and the response of the bottom of the flat bottom hole is not the maximum. when
Ultrasonic incident surface, hole bottom and back are not parallel when there will be angular error.
3.2
Area-amplitude response curve area-amplituderesponsecurve
When the distance from the probe is the same, the response curves of the reflectors with different areas and their ultrasonic responses correspond to each other.
3.3
Metal distance metaldistance
Standard test block from the ultrasound incident surface to the bottom of the flat-bottomed hole distance.
3.4
Ultrasound response ultrasonicresponse
The display height observed on the screen of the ultrasonic testing instrument reflects the amount of ultrasonic energy initially reflected by the standard test block from the bottom of the hole.
