Phased Array Ultrasonic Testing (PAUT) - Welds - Pre-course eLearning Package

If you enrol on a classroom-based course in ultrasonic testing with TWI, you can now ensure you are fully prepared using our pre-course eLearning packages. These entirely optional add-ons allow you to familiarise with all of the key concepts that will be covered in the classroom, giving yourself the best possible chance of learning everything you need to achieve certification.

This option is only available to students enrolling on full courses. 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.

The eLearning part of this training course is divided in six modules:

  • Module 1: Ultrasound

  • Module 2: Phasing

  • Module 3: Steering

  • Module 4: Focusing

  • Module 5: Data Quality

  • Module 6: Review

Each module contains:

  • Pages explaining the underlying theory

  • Videos explaining the theoretical and practical aspects of Phased-Array Ultrasonic Testing,
    Silverlight Interactive exercises in which the student can build a set-up, practice calibration and scanning and learn to evaluate real data        

Prices depend where you will be attending the course - find out more

When you have booked your training, you will receive an email notification with your login details. You will then have 30 days before the course start date to go through the modules.
