Abstract: With the continuous expansion of the production and operation scale of China's coal mining enterprises, their
requirements for technical content and production capacity are gradually improving. However, with the emergence of the trend of
output expansion, it is particularly important to ensure safe production. The detection and inspection of large equipment and
mining materials in coal mines provide a strong guarantee for safe production. As an important item of detection and inspection,
non-destructive testing is widely used in both coal and non-coal production fields in China.

Key words: non-destructive testing technology; ultrasonic testing; penetrant testing; flaw indication; axis parts
