Abstract

Special features of finding cracks under threads of drill pipes and studs of power equipment are considered. Standard angle single-crystal probes, a special normal dual probe, and a probe of head waves were used for ultrasonic testing. They were compared and their efficiency was estimated. The succession of tuning of the scan duration, the depth gage, and the sensitivity of the probe is described.
