Abstract
Ultrasonic-monitoring data for samples cut from defective rolled samples are verified, by comparing the size of the defects according to ultrasonic monitoring and measurements at fractures of actual samples. The error density distribution of ultrasonic monitoring is presented. In estimating the permitted operational loads, the error in the defect dimensions according to ultrasonic monitoring must be taken into account by introducing an additional margin in the strength calculation.
