Critical flaw sizing in ferritic steel is a technique used in a wide range of industries (power generation, petrochemical and refinery, shipping, manufacturing), to evaluate the integrity of equipment and constructions. It is most commonly used in evaluating defects which have arisen in service. It is accepted that all weld will contain some flaws but the question is, how many and what are their sizes?
The detection of sizeable welding flaws is critical to the health, safety and reliability of any high integrity plant and construction. It is essential that the information on location, frequency and size of defects is accurate and can be used in integrity evaluations and remaining life analysis. Standard UT testing techniques will detect flaws but not give the accuracy of information required for assessing the integrity of equipment.
General, specific and practical training is provided daily and formative assessments are used to monitor progress and a final summative assessment is utilised to assess the success of the training programme and to issue a proof of training document. Following the successful completion of the training programme, candidates will be eligible to write the qualification examination conducted by the Personnel Certification Body, where after industrial experience of 9 months in this application; can be gained towards personnel certification.
A proper understanding and competence relating to conventional Ultrasonic testing is mandatory, hence the access condition of UT II certification for this advanced NDT method.
