Time of Flight Diffraction Technique (TOFD-T) as an Alternative to X-Ray Examination for Thick Welds: A Literature Review

Volume 5: High Pressure Technology; Nondestructive Evaluation Division; Student Paper Competition, 2009
In the nuclear industry, and in particular, regarding large steel components including the nuclear steam supply system, weld integrity must be assessed and confirmed during the fabrication process, for the initial field-welds and periodically during in-service follow-up of some critical assembly welds.

Mobile System for Non Destructive Testing of Weld Joints via Time of Flight Diffraction (TOFD) Technique

2012
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

Advantages of Time of Flight Diffraction (TOFD) technic and R6 Structural Integrity Assessment Procedure for Nuclear Power Plant Components

2000
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
