The technique is based on piezoelectric elements arranged in a specific geometry, Controlled independently and simultaneously in transmission and reception.
Phased Array control has a recovery faster and larger than surface areas of parts we want to map regardless of their geometry. This method differs radically from the old conventional ultrasonic by a higher velocity of propagation and signal phase.
The TOFD inspection is an effective method of inspection fully computerized for detection and sizing of defects with unprecedented accuracy to date.
The TOFD technique uses the signals diffraction instead of the signals reflection. The type, location, geometry and orientation of the anomalies are in most cases insignificant for the detection and sizing.
