If you enrol on a classroom-based course in ultrasonic testing with us, you can now ensure you are fully prepared using our pre-course eLearning Suite. These entirely optional add-ons allow you to familiarise with all 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.

Description
The eLearning part of this training course is divided in four modules:
• Module 1: Basic Principles of Ultrasound and Ultrasound Testing
• Module 2: Principles Underlying Time of Flight Diffraction
• Module 3: Data Analysis
• Module 4: Review
Each module contains:
• Pages explaining the underlying theory.
• Videos explaining the theoretical and practical aspects of Ultrasound Testing, Silverlight interactive exercises in which the student can build a set-up, practice calibration and scanning and learn to evaluate
real data.
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.
