SGS organises TOFD training course

The training course will last 11 working days and will take place from 17-27 November 2009.

At the end of the course, an optional examination can be taken in accordance with the SNT or PCN / EN 473 certification scheme.

The exam will be carried out in English and will be conducted on 28 November, in Shanghai, China.

Time of flight diffraction (TOFD) is an ultrasonic testing technique originally developed to increase the sizing accuracy of flaws previously detected by conventional NDT techniques.

TOFD is the most important method for flaw detection and is accepted worldwide.

TOFD has replaced onsite radiography in many cases as it offers strong advantages in terms of safety and required inspection time and costs.

Due to insufficient knowledge about the application of this new technology, flaws have remained undetected, causing a general lack of confidence in the TOFD application.

This is why it is essential to educate NDT technicians about the correct and incorrect use of this test medium and the interpretation of results.

The Personnel Certification in Non-Destructive Testing (PCN) is a program developed by the British Institute of Non-Destructive Testing (BINDT) and provides a reliable and cost-effective method of satisfying NDT personnel qualification and certification and quality-management systems requirements.

The TOFD Training Course by SGS prepares candidates for the PCN examination for Levels 1, 2 and 3.

To be eligible for this course, candidates must hold PCN UT Level 2 Welds training.

Beginning October 26 2009, SGS can provide UT Welds training and examination prior to the TOFD course for candidates that need to complete both the UT Welds and TOFD courses.

The theory will be carefully explained using visual aids such as animated presentation material together with video projection of instrument displays.

For practice examinations, SGS will provide a range of welded samples suitable for TOFD inspection.

All levels of TOFD training courses will include data acquisition.

In addition, Level 2 candidates are required to prepare a written instruction for a Level 1 candidate to follow for data acquisition on a particular sample.

Level 3 candidates are required to create a procedure that includes a complete inspection technique.

Throughout the duration of training, practical experiments and continuous assessments will be conducted to monitor the candidate's progress and understanding of TOFD.

The course fee includes the training, examination fee and PCN levy cost.
