Click here for a video showcasing MISTRAS' Phased Array technology.
Phased array technology generates an ultrasonic beam with the capability of setting beam parameters such as angle, focal distance and focal point size through computer controlled excitation. Furthermore, this beam can be multiplexed over a large array. These capabilities offer a series of possibilities. For instance, we can now quickly vary the angle of the beam to scan a part without moving the probe, and replace multiple transducers with a single element that produces various angle beams electronically. Inspecting a part with a variable angle beam also maximizes detection regardless of the defect orientation, while optimizing signal-to-noise ratio.

Phased Array applications include, Angle beam inspection primarily used for weld inspection, Time of Flight Diffraction (TOFD) for detection and sizing of defects and the ability to more readily inspect complex geometries. For weld inspection Phased Array increases the probability of detection by offering the inspector additional tools to visualize the reflectors and their position within the weld. The ability to record the weld scans also allows us to utilize phased array for many projects that are constructed to ASME Code requirements.
