What type of data does the display unit visualize in phased array testing?

In phased array testing, the display unit visualizes gathered inspection data, which includes the results of the assessment being conducted on the test material. This inspection data consists of various signals obtained from the ultrasonic transducers as they probe the material. The display unit processes these signals to produce images or waveforms that professionals can analyze to identify any flaws, defects, or irregularities within the material being tested.

Visualization of this inspection data is crucial as it allows the operator to assess the integrity of the material, make decisions about its reliability, and interpret findings effectively. This visualization often includes indications of reflection patterns, amplitude, and time-of-flight, which provide insight into the internal structure of the material. While environmental conditions, weld dimensions, and calibration parameters are important factors in the testing process, they are not the primary focus of what the display unit presents during the inspection.
