Phased array ultrasonic imaging using an improved beamforming based total focusing method for non destructive test
One of the novel ultrasonic phased array based scanning methods for ultrasonic imaging in non-destructive test is total focusing method (TFM). This method employs maximum available information of the phased array elements and leads to an improved defect detection accuracy compared to conventional scanning methods. Despite its high detection accuracy, TFM behaves weak in distinguishing the real ...

متن کاملNon-Destructive Inspection of Components with Irregular Surfaces using a Conformable Ultrasonic Phased Array
A conformable phased array device is being developed that allows reliable ultrasonic inspection of components with irregular surfaces. The device uses a standard linear phased array transducer, which is coupled to the surface under test by a water path, encapsulated by a low loss, synthetic rubber membrane. A comparison of results obtained using conventional ultrasonic techniques and the confor...
متن کاملGroundwork for Rail Flaw Detection Using Ultrasonic Phased Array Inspection
An apparent increase in the detectability of certain flaws results when the ultrasonic inspection beam was oriented off the longitudinal axis of railroad rail. Here, artificial reflectors were used to better define the extent of material "seen" by inspection beams, and determine how surface curvature might affect the inspection. Presumably, such information could be useful for suggesting optimu...
متن کاملA Phased Array Ultrasonic Testing Technique for the Inspection of Nozzle Welds in the Nuclear Industry
Regular, in-service inspection is important to verify the integrity of welded nozzle sections in the nuclear industry. Nozzle sections are susceptible to crack growth due to thermal fatigue and stress corrosion. Early detection of cracks is therefore essential to ensure the continued safe operation of the facility. The aim of this project is to design an inspection system that is capable of red...
