Ultrasonic Testing (UT) – Levels 1 and 2 - Refresher eLearning Package

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.

Has your PCN NDT certification been voided? TWI can help… Find out more.

The Refresher eLearning Package is divided in three modules:

  •  Module 1: Self-evaluation Test

  •  Module 2: Theory

  •  Module 3: Exercises 

Price - £350 + VAT

When you have booked your online training, you will receive an email notification with your login details.
