SGS, an inspection and certification company, is organising a Non-Destructive Testing (NDT) training course, with focus on the ultrasonic testing method, Time of Flight Diffraction (TOFD).

The course will take place on November 17-27, 2009, after which an optional examination, which is in accordance with the SNT or PCN / EN 473 certification scheme, can be taken.

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

Time of Flight Diffraction (TOFD) is an Ultrasonic Testing Technique developed to increase the sizing accuracy of flaws previously detected by conventional NDT techniques.

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 who need to do both UT Welds and TOFD.

The theory will be 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 Time of Flight Diffraction 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 which includes a complete inspection technique.

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