AI Technical Summary

Technical Problem

Existing penetrant testing devices are difficult to accurately compare the sensitivity of different penetrant testing materials or processes, and traditional test blocks have poor reproducibility and are difficult to manufacture, especially in terms of crack size control.

Method used

Design a permeate sensitivity detection device comprising a slider and a sleeve. The outer surface of the slider is provided with a detection groove and a through groove, and the sleeve is provided with a channel. The slider and the limiting plate are fixed by a threaded connection. The size of the detection groove is adjustable, which facilitates disassembly and cleaning, and allows direct observation of the permeation situation to compare sensitivity.

Benefits of technology

It achieves efficient and accurate permeate sensitivity comparison detection, can be reused multiple times without affecting detection accuracy, avoids changes in the size of the detection tank caused by stress input, simplifies the operation process, and improves the reliability of test results.
