Time of Flight Diffraction (ToFD)

This course is suitable for individuals with ultrasonic testing experience, who are looking to expand their knowledge into advanced ultrasonic applications and gain a qualification in Time of Flight Diffraction (ToFD).

What will I learn?

This course covers ToFD theory and principles of diffraction, ToFD hardware (pulsers, receivers, motor control, encoders), ToFD data acquisition and interpretation, ToFD techniques, and ToFD applications. You will also learn about equipment selection, calibration and optimisation, optimising PCS and angles, flaw location and sizing, limitations of detection and resolution, codes and standards, and reporting.

The training is in accordance with the requirements of ISO 9712 and ends with the certification examination.

What will I leave with?

By the end of the course, you should be able to:

Understand the theoretical background and limitations of ToFD applications

Correctly select probe/wedge to examine welded butt joints

Calibrate and set up the ToFD ultrasonic equipment

Locate and evaluate flaws in the weld body and HAZ

Differentiate defects from geometric features

Analyse scan data for location and size of defects in typical welded butt joints

Understand and apply digital processing processes (SAFT, linearization, averaging, filters etc)

Compile written instructions

Meet the CSWIP and PCN syllabus requirements

ENTRY REQUIREMENTS

CSWIP candidates should be qualified to a minimum of BS EN ISO 9712.

CSWIP certification is also available for candidates holding ASNT UT Welds. It will be considered on an individual basis and evidence of training and experience presented to the training centre on application. Non-BS EN ISO 9712 certificate holders will be required to sit the CSWIP UT Welds Level 2 General Paper.

Certification requirements:

The minimum duration for experience prior to or following success in the qualification examination is:

Level 1 - 1 month for CSWIP 

Level 2 - 3 months for CSWIP (Direct Level 2: 4 months)
