  • 1. ULTRASONIC TESTING N D T What is the principle ? Transducer ( PROBE) Weld Defect (Flaw) Flaw detector CRT screen

2. PROPERTIES OF SOUNDWAVES Ultrasonic vibrations travel in the form of a wave, similar to the way light travels. = v/f = Wavelength v = material sound velocity f = frequency ULTRASONIC TESTING N D T 3. Wave Propagation and Particle Motion: Longitudinal Wave : Particle Motion is in the direction of wave propagation. Shear Wave : particle motion is perpendicular to the direction of the propagation. ULTRASONIC TESTING N D T 4. SOUND FIELD ULTRASONIC TESTING N D T Far Field. Near zone Farzone Near Field 5. What are the techniques ? Pulse-echo Through transmission Contact Immersion tech. ULTRASONIC TESTING N D T 6. ULTRASONIC TESTING N D T B-SCAN C-SCAN A-SCAN What are the Display methods ? 7. What is an Ultrasonic Transducer? Ultrasonic transducer works on piezo-electric principle that converts electrical energy to mechanical energy, in the form of sound, and vice versa. ULTRASONIC TESTING N D T quartz 8.
