Time of Flight Diffraction Ultrasonic Testing (ToFD)
The ToFD course is for everyone needing comprehensive knowledge on ToFD ultrasonic testing level 2 in practice as well as the method’s application areas.
Time-of-Flight-Diffraction (ToFD) is a supplemental course for inspectors with practical experience and a UT-2 welding certificate who are going to use ToFD in the industry. The course meets the training requirements of EN ISO 9712.
The course in the ToFD ultrasonic testing method is a mix of theory and practical exercises. Through examination of many different test specimens and geometries with the ToFD inspection method, you will get a good understanding of the method’s applications, benefits and limitations. All practical exercises are initiated and monitored by our qualified instructors.
Every day, home assignments reviewing the ToFD theory are handed out and reviewed and discussed the following day together with the instructors.
The following topics will be covered during this ToFD ultrasonic testing course:
- Theory and principles of ToFD ultrasonic testing
- Choice of probes
- Review of method and acceptance standards
- Practical exercises in ToFD ultrasonic testing
- Defect detection, positioning and sizing
- Analysis of scanning data
- Reporting of findings
- Making of instructions
To participate in the ToFD course it is required that your math skills is at an elementary school level, as calculations are recurring in the lessons, the homework assignments and the exam.
Benefits from completing the Time of Flight Diffraction (ToFD) course
The course will give you a thorough theoretical and practical education in the ToFD method. We will make sure you get an adequate theoretical and practical foundation to be examined on level 2 in time-of-flight-diffraction ultrasonic testing in accordance with EN ISO 9712. After certification, you can perform the ToFD ultrasonic testing in practice in the industry.
To complete the ToFD course, you must pass an exam consisting of a theoretical and practical part:
