Ultrasonic Testing (UT) is an advanced non-destructive testing method that utilizes high-frequency sound waves to detect discontinuities within a material. Due to its high sensitivity and ability to provide precise depth information for internal flaws, it is extensively used in critical engineering applications.
The UT Training, provided under the framework of EN ISO 9712, is a comprehensive program designed to equip participants with the physical principles of ultrasonics, equipment operation, evaluation techniques, and the competence to perform inspections in compliance with international standards.
The primary objectives of this training are to:
Instruct participants on the technical principles of ultrasonic waves.
Ensure the accurate detection and characterization of internal discontinuities.
Develop proficiency in equipment operation and calibration.
Cultivate the competence to evaluate results and generate technical reports according to standards.
Establish the technical knowledge base required for Level I, II, and III qualifications.
The training program covers the following technical modules:
Propagation of sound waves in solids.
Reflection, refraction, and attenuation.
Acoustic impedance.
Wave modes: Longitudinal (compression), Transverse (shear), and Surface (Rayleigh) waves.
Straight Beam (Normal) Probes: For thickness measurement and lamination detection.
Angle Beam Probes: Primarily used for weld inspections.
Contact vs. Immersion testing techniques.
Introduction to advanced techniques: TOFD (Time of Flight Diffraction) and Phased Array (PAUT).
Operation of ultrasonic flaw detectors and various transducers (probes).
Use of reference/calibration blocks (V1, V2, etc.).
Sensitivity settings and calibration methods.
Signal evaluation curves: DAC (Distance Amplitude Correction), TCG (Time Corrected Gain), and DGS/AVG diagrams.
EN ISO 17640: Ultrasonic testing of welded joints.
