使用自动化设备对棒材进行超声水浸检测时,灵敏度的设置直接影响产品的检测结果。为了获得水浸探头对被检棒材检测灵敏度的影响因素,选取水浸探头设计试验验证不同参数的影响程度。结果表明,水程距离不是影响检测灵敏度的关键因素,探头偏转角度对灵敏度影响很大。 When using automated equipment to perform ultrasonic flooding tests on bars, the sensitivity setting directly affects the product’s test results. In order to obtain the influencing factors of the detection sensitivity of the immersed probe to the tested rod, the immersion probe design test was used to verify the influence of different parameters. The results show that the waterway distance is not the key factor affecting the detection sensitivity, and the deflection angle of the probe has a great influence on the sensitivity.
