WHAT MAKES PHASED ARRAY GREAT

Share on FacebookShare

The Phased array ultrasonic technology for NDT use was triggered by the following power generation inspection problem. 1. The need to detect crack located at different depth with random orientation using the same probe in a fixed position. 2.The requirements to improve SNR signal to noise ratio and Sizing capability for dissimilar metal weld 3.The requirements to increase scanner reliability 4 . increased accessibility to reach difficult component like PWR/BAR 5 Decrease set up and inspection time. 6.The requirements to increase the accuracy in detection sizing location, and orientation of critical defect. 7.Speed, Flexibility, small probe dimension 8.A requirements to decrease the amount of radiation personnel are exposed too.
