Time of Flight Diffraction (ToFD) - Appreciation eLearning Package

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

What will I leave with?

This eLearning package will provide you with an appreciation of Time of Flight Diffraction principles and data analysis. Upon completing the full package you will be awarded a Certificate of Satisfactory Completion.
