Time-of-flight diffraction (TOFD) technique for accurate sizing of cracks embedded in sub-cladding
Insight - Non-Destructive Testing and Condition Monitoring, 2003This paper deals with an experimental study for evaluation of the TOFD technique for determination of size of cracks embedded in sub-cladding. It extends the results presented in the previous papers ( 1 , 2 ) . The studywas confined to simulated cracks (machined slits) underneath the cladding.

This paper describes research towards the development of a robotic system for automated welded joint testing. The tests are often carried out manually by skilled personnel. Automating the inspection process would reduce errors and associated costs. The system proposed in this paper is based on a mobile robot platform and is designed to carry ultrasonic

In service inspection (ISI) of aged power plant parts has a delicate task to provide information on presence, position, orientation and size of defects in material. As far as results of ISI are just a starting point for elaborate procedure of structural integrity assessment, the accuracy and reliability of these results are particularly important. Time
