Which type of data representation is favored in PAUT due to its ability to show anomalies clearly?

In Phased Array Ultrasonic Testing (PAUT), the use of 2D and 3D graphical imaging is favored because it provides a visual representation that allows for clear identification of anomalies. This graphical representation can effectively illustrate the location, size, and shape of defects within the test material.

Graphical imaging enhances the understanding of the internal features of components being inspected, making it easier for technicians to interpret data quickly and accurately. The visual information can highlight subtle variations in the material that might not be apparent through numerical or textual data alone. This visual clarity is crucial in industrial applications where the integrity of materials is under scrutiny, as it aids in making informed decisions based on inspection results.

In contrast, other types of data representation, like tabular formats or text descriptions, offer limited visualization of anomalies, making it more challenging to assess complex issues in materials. Physical sample examinations, while useful, do not provide the same level of detail about internal features as graphical imaging.
