Ultrasonic Phased Array technology has recently revolutionized the way we perform bridge pin testing. Pins can now be ultrasonically tested using probes with multiple elements which allow the sound beams to be focused and transmitted through the pin at multiple angles and in a sweeping motion, thus picking up discontinuities oriented in any direction. This technology comes from the medical industry and works the same as that experienced during ultrasonic scans of women during pregnancy.

The focusing and steering of the ultrasonic beam at an aray of angles when displayed creates a visual image. As you can see in the series of images attached, the display better represents the volume of material under test. Portable Phased Array Ultrasonic Testing greatly increases the reliability of the testing process
