• Organise and report the results of non-destructive tests
• Meets syllabus requirements for Level 2 – PCN or EN 473

Principles of Ultrasonic Testing

• Generation of ultrasonic waves
• Properties of the transducer or probes
• Acoustic impedance, Beam Divergence – Dead, Near and Far zone
• Influence of properties of test object on sound propagation
• Sound velocity and attenuation
• Equipment - controls and functions of ultrasonic instrument
• Signal presentation - A, B, C and D scans
• Scanning techniques – manual, semi-automatic, automatic
• Immersion testing and Through-transmission technique - basic principle
• Calibration of Testing Systems
• Sensitivity setting – simple methods, BWE, DAC
• Delectability of Defects – advantages and limitations of the test method with regard to defect detection
• Factors Affecting the Performance of the Ultrasonic Test
• Conducting and Recording the Test
• Procedure to be adopted to carry out the test and Flaw assessment, sizing techniques and reporting
• Snell's Law concerning reflection, Refraction, mode conversion and Calculations
• Interpretation of Test Results to acceptance standards
• Basic Welding Processes and product technologies
• Types of defect associated with particular parent metal/welding process combinations
• Examination of parent plate, butt welds and configuration joints
