Ultrasonic testing involves three key concepts:
1. Sensitivity refers to the ability of the system to detect the smallest specified defect at the maximum testing range, which depends on factors like the probe, flaw detector, material properties, and signal-to-noise ratio. Methods to set sensitivity include using the smallest defect, back wall echo, and artificial defects.
2. Sizing defects involves techniques like the 6dB drop method where the probe is moved until the echo is half the original height, or the maximum amplitude method for irregular defects where the probe is moved to find the peak signal.
3. Techniques like equalization and 20dB drop also help size defects by observing the echo levels and drop-off
Ultrasonic testing
Ultrasonic testing of steel castings requires careful calibration of ultrasonic instruments and probes to ensure accurate results. Key steps in calibration include:
1. Using reference blocks of known thickness to set the time base and zero point for thickness measurements.
2. Checking the linearity of the amplifier and time base by verifying a constant ratio between echo heights at different sensitivity levels.
3. Assessing the penetrating power by counting echoes from a thick plexiglass block, and relative sensitivity by measuring echo height from a small hole.
4. Measuring the dead zone by finding the minimum distance for visible echoes.
5. Checking resolving power by verifying that echoes from different depths within

Liquid Penetrant Testing L-III presentation prepared by MAHESH PANDIT,OMNDT,J...
The document provides information on the basic principles of liquid penetrant testing (PT). It discusses how PT works via capillary action, with low surface tension penetrant entering surface-breaking discontinuities. It explains factors that influence penetrant dwell time and the ability to detect flaws. It also covers visual acuity of the human eye in PT, the history of the technique, basic processing steps, and the importance of cleaning surfaces to be tested.

1) Ultrasonic testing techniques include pulse echo, through transmission, and transmission with reflection. Pulse echo uses a single probe to send and receive sound to detect defect depth and orientation. Through transmission uses probes on opposite sides to detect defects but not location. Transmission with reflection can locate defects.
2) The sound beam has a near zone where intensity varies and a far zone with exponential decay. The near zone length depends on probe frequency and diameter, with higher frequency and larger diameter increasing length.
3) Beam spread is smaller with higher frequency and larger diameter probes. Compression waves have a smaller beam spread than shear waves. Snell's law and critical angles determine how sound refracts between materials
Ultrasonic testing
This document provides an overview of ultrasonic testing. It begins with an introduction and outline. It then covers the basic principles of sound generation and propagation. The principles of ultrasonic inspection using pulse-echo and through transmission techniques are described. Details are provided about ultrasonic test equipment including transducers, instrumentation, and calibration standards. The advantages and limitations of ultrasonic testing are summarized.
