Is it for me?

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 time is an issue, please consider our blended learning option - study theory and concepts when and where you choose, then join the classroom sesssions for hands-on practical.

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.

FREE PRE-COURSE ELEARNING PACKAGE - available only to students enrolling on this course:
Familiarise yourself with the theory and key concepts that will prepare you for the classroom training with the ToFD Pre-course eLearning Package.
The eLearning material is made available 30 days before the course start date, giving you plenty of time to build your confidence before you enter the classroom.

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
