摘要
超声探伤仪的计量精度对于其功能的发挥有着不容忽视的影响,而其在使用过程中,会受到各种因素的影响,导致计量结果出现偏差,因此,需要定期做好对于超声探伤仪的计量检定工作。从保障超声探伤仪性能以及计量精准性,充分发挥仪器计量功能的角度,对超声探伤仪的计量检定工作进行了研究和讨论。在研究中,明确了超声探伤仪计量检定的流程及注意事项,针对其动态范围、水平线性、垂直线性以及灵敏度、误报率、分辨力等进行了检定。对比检定前后,超声探伤仪的计量精度得到了显著提升,可以将自身的性能充分发挥出来,从而保障超声探伤结果的准确性及可靠性。
Ultrasonic flaw detector itself has the characteristics of high detection accuracy,fast detection speed,small size,light weight,and its own ultrasonic non-destructive testing,so it has been widely used in many fields.The measurement accuracy of ultrasonic flaw detector has a non-negligible impact on its function,and it will be affected by various factors in the use process,leading to the deviation of the measurement results.Therefore,it is necessary to do a good job of the measurement verification of ultrasonic flaw detector regularly.The metrological verification of ultrasonic flaw detector is studied and discussed from the Angle of ensuring the performance and measurement accuracy of ultrasonic flaw detector and giving full play to the function of the instrument.In the study,the metrological verification process and precautions of ultrasonic flaw detector are defined,and its dynamic range,horizontal linearity,vertical linearity,sensitivity,false positive rate and resolution are verified.The measurement accuracy of ultrasonic flaw detector has been significantly improved before and after comparative verification,and its own performance can be fully brought into play.
