Is it for me?

This course is designed for technicians who are already certified, but would benefit from a reminder of the fundamentals of Phased Array Ultrasonic Testing (ToFD). This refresher eLearning package is an excellent way to remind yourself of the underlying principles and skills required to conduct this type of inspection.

Refresher courses are available for 14 days consecutive access from the date of activation. During that time they can be completed entirely at your own pace, with the option to repeat any sections as needed.
