The maximum extent or magnitude of a wave or signal, often used to measure the strength or intensity of a detected flaw or signal.
An electric current that periodically changes direction, commonly used in eddy current testing and impedance-based techniques.
The speed at which sound waves propagate through a medium, typically measured in m/s.
The measure of the resistance encountered by sound waves as they propagate through a medium. The value of this material property is the product of the material density and sound velocity.
The process by which sound waves lose energy as they propagate through a material.
An eddy current testing probe that is designed to provide a reference signal or baseline measurement. It is used to establish a calibration standard and compensate for variations in material properties or probe characteristics during inspections.
A method used to identify and locate the presence of leaks or unintended fluid or gas flow in a system or component. It involves pressurizing or introducing a test medium into the object and monitoring for any pressure drop or the appearance of indicators, such as bubbles or audible sounds.
A non-destructive testing method that relies on the human eye or optical instruments to examine the surface, appearance, and overall condition of objects. It involves a thorough visual examination to identify visible defects, anomalies or irregularities, such as, cracks, corrosion, wear, and other visible signs of damage or deterioration.
A non-destructive testing technique that detects and analyzes the release of transient stress waves or acoustic emissions from materials and structures. It involves placing sensors on the object and monitoring for high-frequency signals generated by internal changes, such as crack propagation or structural deformation.
A non-destructive testing method used to detect surface discontinuities in various materials. It involves applying a liquid penetrant, typically a colored dye or a fluorescent substance, to the surface of the object. The penetrant seeps into any surface cracks or imperfections through capillary action. After cleaning off excess penetrant, a developer is applied to draw …
