For angle beam testing, what is a common use of special wedges?

In angle beam testing, special wedges are commonly used to improve the resolution of the ultrasonic testing. These wedges are designed to facilitate the transmission of ultrasound waves at specific angles to optimize detection of discontinuities in the material being inspected. By using a wedge that appropriately matches the material properties and testing conditions, the sound beam can be directed more effectively into the component, enhancing the clarity of the signals received. This results in more precise identification and characterization of flaws.

The resolution is particularly important in detecting smaller or less significant discontinuities, as a higher resolution allows for better differentiation between defects and the surrounding material. This improves the overall effectiveness of the inspection process, allowing for accurate assessment of the integrity of the structure being tested. Therefore, the use of special wedges directly influences the clarity and detail of the data obtained during angle beam testing, making them a crucial tool for achieving reliable results.
