Is it for me?
This course is suitable for ultrasonic testing equipment vendors, auditors or supervisors – anyone who works indirectly with ultrasonic testing. The Time of Flight Diffraction Appreciation eLearning package brings you into contact with ultrasonic testing, even if the testing is conducted by someone else.
This eLearning package gives you 60 days access to the eLearning materials. The training is delivered step by step, one section at a time, but free of any time pressure to complete the individual modules.

What will I learn?
The Time of Flight Diffraction Appreciation eLearning Package covers both manual and semi-automated PAUT and is divided in three modules:
Module 1: Basic Principles of Ultrasound Testing
- NDT, sound and ultrasound, basic notions, waves, dB system
- Probes, wedges
- Scans and views
- UT production, wave propagation, coverage, techniques
- Procedures and set-up
- Calibration
- Inspection and data management
Module 2: Principles Underlying Time of Flight Diffraction (ToFD)
- Butt welds
- Digital instrument, probes, wedges, scanners
- Diffraction, refraction, pitch and catch technique
- Beam spread, limitations
- Type of scans, views, cursors
- ToFD set-ups, essential variable
- Pre-scanning calibration, beam index point, velocity
- Scanning
- Calibration of wedge delay, lateral wave removal and straightening
Module 3: Data Analysis
- B-Scan perspective
- Lateral wave, backwall and mode-converted backwall signals
- Effect of beam spread on depth and the backwall signa
- Indication classification, probe position vs. height, angle vs height
- Geometrical indications, double-V welds, pipes misalignment, different wall thickness
- Data quality, calibration, basic analysis, detailed analysis
- Signal start, grouping, point-like indications
- Height and depth, top-surface breaking, bottom-surface breaking, embedded
- Length and position, parabolic shape, elongated and curved
- Interactive defect viewer: top-surface breaking, bottom-surface breaking, embedded
