Course Title:
Ultrasonic Testing (UT) - Welds - Refresher eLearning Package

'There are no events currently scheduled for this course

Suitable for:

For technicians who are already certified, but would benefit from a reminder of the fundamentals of Ultrasonic Testing, we are introducing a refresher eLearning package. This course 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.
