Abstract

The invention discloses a portable calibration / reference test block for ultrasonic nondestructive testing. The portable calibration / reference test block comprises a body, a left side arc surface arranged on the left side of the body, a right side arc surface and a right-angle limb side which are arranged on the right side of the body, a transverse hole formed in the middle of the body, and a measured refraction angle arranged in the middle of the body. The block can be used for ultrasonic detection and is simple to process; the test block is small in size; and parts of functions of the CSK-IA test block and the CSK-IIA test block are designed on one test block in a centralized manner, so that the requirement of on-site checking is met.

Description

technical field [0001] The invention belongs to the field of non-destructive testing, and in particular relates to a portable calibration / comparison test block for ultrasonic non-destructive testing, which is used for adjusting and checking the test block probe of field instruments for ultrasonic testing, and can also be used for sensitivity adjustment of ultrasonic testing distance-amplitude curves , characterized by simple processing and small size of the test block; part of the functions of the two test blocks CSK-IA and CSK-IIA are designed on one test block to meet the needs of on-site verification. Background technique [0002] The test block is one of the important equipment for ultrasonic flaw detection. In the process of ultrasonic flaw detection by pulse reflection method, the position, height, and static and dynamic characteristic variables of the reflected echo on the fluorescent screen of the instrument are used to characterize the quality of the inspected mater...
