What is the purpose of color mapping in phased array ultrasonic testing?

Color mapping in phased array ultrasonic testing serves the essential purpose of visually representing the amplitude or properties of detected signals. By using color scales, operators can immediately identify variations in signal strength, which are indicative of different material characteristics, such as flaws or inconsistencies within the test material. The color-coded data helps in quickly distinguishing areas that require further assessment or signify defects, making it easier to interpret results at a glance.

This method enhances the detection process by allowing for a more intuitive understanding of the signal response obtained from the inspection of components. Having a color-coded representation streamlines the identification of critical information without needing to constantly refer to numerical data, facilitating a more efficient assessment of the part being tested.
