Time of Flight Diffraction (ToFD)
Provider TWI
Course description
This course covers Time of Flight Diffraction 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.
- 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.
- Knowledge of ToFD Theory and Principles.
- Knowledge of calibration of ToFD equipment.
- Flaw detection and evaluation.
- Data interpretation and analysis.
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). If you are working in ceramics or material science and you have an interest in learning more about Time of Flight Diffraction, then this course is of benefit to you.
If time is an issue, please consider our blended learning option - study theory and concepts when and where you choose, then join the classroom sessions for hands-on practical.
10 days of training delivered in-person or blended training, led by a TWI facilitator.
