Keywords:
non-destructive testing, ultrasonic method, flaw detector, ultrasonic standard measurement blocks, accuracy, ultrasound examination, measurement, nominal valueAbstract
This article considers the assessment of the absolute error of ultrasonic flaw detectors, which is used in the ultrasonic method of non-destructive testing, using ultrasonic standard measurement blocks when determining the distance of defects in metal products.
