Description
Technical Field
The invention relates to a test block cross hole measuring scale for ultrasonic detection, which is used for accurately measuring the height of the circle center of a test block cross hole and a scanning surface, and the horizontal distance or the outer arc length between the front edge/incident point of a probe and the circle center of the cross hole.
Background
The performance indexes (probe deflection angle, deviation, incidence point, sound beam angle and the like; test block size precision and the like) of the ultrasonic probe and the test block directly influence the A-type pulse reflection ultrasonic sound beam directivity and the effectiveness of defect positioning and quantification. Standards have more stringent control requirements for probe performance indicators, such as: when the central frequency of a single crystal inclined probe is less than 2MHz in NB/T47013.3-2015, the deviation of an actually measured sound beam angle and a nominal value is less than or equal to 3 degrees when the central frequency is more than or equal to 2MHz, the deviation of the actually measured sound beam angle and the nominal value is less than or equal to 2 degrees when the central frequency is more than or equal to 2MHz, and the measurement of the sound beam angle is obtained by the measurement of a standard reflector (a transverse hole, an arc surface, a flat bottom hole and a notch) of a calibration test block through instrument calculation, so the size error of the standard reflector of the test block has great influence on the performance index of the probe.
In the ultrasonic detection process of the welded joint of the pressure-bearing equipment, parameters such as the depth, the incident point and the like of a standard transverse hole reflector of a test block are mostly measured by adopting a steel plate ruler/vernier caliper, and when parameters such as the transverse hole depth, the horizontal offset and the like of non-planar test blocks such as GS, RB-C, RB-L and the like are measured, the positioning claw of the vernier caliper is basically linear, and the measuring point cannot be accurately positioned; (2) the size radius of the transverse hole is small, and the distance between the center of the transverse hole and the surface of the test block cannot be directly measured; (3) the depth of the RB-L transverse hole and the horizontal deviation value cannot be measured and verified; in addition, NB/T47013.3-2015 requires that the error of the shape and the size of the test block is less than or equal to +/-0.05 mm, and after the test block is polished, if a steel plate ruler/vernier caliper is still adopted in the process of checking the corrosion and the mechanical damage of the surface of the test block, the error of the measurement result is larger. Therefore, aiming at the characteristics of the A-type pulse reflection ultrasonic detection standard transverse hole reflector, the measuring tool with higher operability is adopted, so that the test block measuring accuracy can be improved, the operating processes of probe performance index verification, DAC \ TCG manufacturing, test block annual check and the like are standardized, and the measuring result is convenient for implementing the standard requirement.
