Utility model content
For above-mentioned defect of the prior art, the purpose of this utility model is a kind of low-voltage electrical apparatus electrical contact UT (Ultrasonic Testing) stepped ramp type test piece of design, this workpiece can coordinate A, C ultrasound scanning, detects the thickness resolving power of ultrasonic probe and the performance index of penetration power quickly and easily.
For realizing above-mentioned object, the technical solution adopted in the utility model is:
The utility model provides a kind of low-voltage electrical apparatus electrical contact UT (Ultrasonic Testing) stepped ramp type test piece, comprise test block, described test block is thickness resolution test block, described thickness resolution test block is respectively arranged with identical, the highly different staged step of width.
Preferably, described thickness resolution test block uses ultrasonic probe to test different thickness, and in conjunction with A, C scan-data, obtains the resolution characteristic of ultrasonic probe to thickness.
Preferably, described staged step is that two rows are arranged on described thickness resolution test block.
More preferably, often arrange described step and be all set to 4 boss.
Preferably, the height of described boss is distributed within the scope of 0.5 ~ 8mm, and becomes arithmetic progression to distribute, and tolerance can be 0.25mm, 0.5mm, 0.8mm, 1.0mm.
More preferably, first row 4 described boss, thickness sets gradually as 1.0mm, 3.0mm, 4.0mm, 2.0mm from left to right; Second row 4 described boss, thickness sets gradually as 0.5mm, 2.5mm, 3.5mm, 1.5mm from left to right.
Owing to have employed technique scheme, the beneficial effects of the utility model are:
The utility model test piece can coordinate ultrasound scanning, completes the demarcation of ultrasonic probe thickness resolving power; Meanwhile, the utility model is simple, be easy to get, and the test block specified in alternative multiple standards, increases work efficiency, and has highly application value.
