1. ULTRASONIC PHASED ARRAYS TESTING

2. ULTRASONIC PHASED ARRAYS  Use a multiple element probe  Output pulse from each element is time delayed to produce constructive interference at a specific angle and a specific depth  These time delays can be incremented over a range of angles to sweep the beam over the desired angular range

3. ULTRASONIC PHASED ARRAYS  Allows the user to control parameters to create an image of the test part, enhancing defect detection and speed of testing  The system includes a sophisticated computer-based instrument that is capable of: - driving the multi-element probe - receiving and digitizing the returning echoes - plotting that echo information in various standard formats

4. ULTRASONIC PHASED ARRAYS Checking phased array probe resolution to determine flaw definition and sizing accuracy. (Instrument: Phasor)

5. ULTRASONIC PHASED ARRAYS  Advantages: a) Ability to sweep a range of angles b) Ability to display the image in real time for the swept angles c) Ability to focus  Applications: Weld Inspection, Crack Detection, Corrosion Mapping, Aerospace and Composite Testing.
