Description

A Measuring Device for Measuring the Hole Depth of an Ultrasonic Test Block

technical field

The utility model relates to the technical field of ultrasonic test blocks, in particular to a measuring device for measuring the hole depth of ultrasonic test blocks.

Background technique

Ultrasonic test blocks include standard test blocks (such as CSK-IA), comparative test blocks (such as CSK-IIA, CSK-IIIA, RB-2, etc.), and simulated test blocks (such as welding simulated defect test blocks). Before calibration, the instrument should be calibrated, such as calibrating sound velocity, zero offset, K value, etc., using CSK-IA test block, so that the instrument can obtain the same sound velocity and related parameters as the tested material. The purpose of comparing the test block is to After a defect is found, the defect reflection wave will have a certain height. Generally speaking, the higher the defect reflection wave is, the larger the defect is. To measure the specific size of the defect wave at a certain height, a comparison test block is required. The comparison test block generally has a horizontal hole , compare the amplitude of the defect wave with the amplitude of the horizontal hole. If the wave height of the defect is higher than that of the horizontal hole, the wave indicates that the defect is more serious than the horizontal hole. The simulated test block is mainly to check whether the probe instrument system and the detection process can detect the defect. If it can be detected, the probe instrument system and detection process are effective, otherwise it is invalid.

When measuring the hole of the ultrasonic test block, it is necessary to use a measuring device to accurately measure the hole of the ultrasonic test block. Most of the existing measuring devices are only a ruler for measurement, and the operator will produce errors when measuring and reading, which makes the measurement The final reading will cause a large deviation. At the same time, the operator needs to read after the measurement, and the reading cannot be accurately performed in a dark place.
