  • PCN Phased Array Ultrasonic Testing (PAUT)

    Phased array ultrasonic testing (PAUT) is an advanced method of ultrasonic testing that has applications in Industrial Nondestructive Testing. The PA probe consists of many small ultrasonic transducers, each of which can be pulsed independently. By varying the timing, for instance by making the pulse from each transducer progressively delayed going up the line, a pattern of constructive interference is set up that results in radiating a quasi-plane ultrasonic beam at a set angle depending on the progressive time delay. In other words, by changing the progressive time delay the beam can be steered electronically. It can be swept like a search-light through the tissue or object being examined, and the data from multiple beams are put together to make a visual image showing a slice through the object. The beam is controllable because a phased array probe is made up of multiple small elements, each of which can be pulsed individually at a computer-calculated timing. The term phased refers to the timing, and the term array refers to the multiple elements.

    NDTS India (P) Ltd is your one stop shop for PCN Phased Array Ultrasonic Testing Method level II in Mumbai.

    Advantages of Phased Array Ultrasonic Testing technique

    • Increased coverage and detection capabilities through multi-angle, electronic rastering and beam control
    • Imaging and recordable data in manageable file sizes viewable by all parties as needed.
    • Inspection of complex geometries
    • Reduced mechanics and difficulties over multi-probe techniques
    • Application of traditional ultrasonic acceptance criteria

    Limitations of Phased Array Ultrasonic Testing Techniques:

    • Greater cost of equipment
    • Greater complexity of use, calibration and require more highly trained personnel.

    It is evident from the observations above that Phased Array Ultrasonic Testing (PAUT) training is a great idea. NDTS facilitates an in depth PCN Phased Array Ultrasonic testing training course. We conduct phased array ultrasonic testing course and our sole aim is that the trainee should receive QUALITY phased array ultrasonic testing training.

    A PCN PAUT Level II Training at NDTS Mumbai is an excellent first step to mastery in phased array ultrasonic testing techniques and a trainee would be able to immediately see the benefits in phased array ultrasonic testing. Some of the other courses offered are PCN UT Level II, PCN TOFD Level II.

    Responsibilities of Certified PAUT Level II

    An individual certified to Phased array Ultrasonic Level 2 has demonstrated competence to perform NDT according to Phased array Ultrasonic Testing procedures. Within the scope of the competence defined on the certificate, Level 2 personnel may be authorized by the employer to

    • Select the Phased Array Ultrasonic Testing technique for the test method to be used;
    • Define the limitations of application of the testing method;
    • Translate NDT codes, standards, specifications and procedures into NDT instructions adapted to the actual working conditions;
    • Set up and verify equipment settings;
    • Perform and supervise tests;
    • Interpret and evaluate results according to applicable standards, codes, specifications or procedures;
    • Carry out and supervise all tasks at or below level 2;
    • Provide guidance for personnel at or below level 2;
    • Report the results of Phased Array Ultrasonic test.

    The PCN requirements of Training Hours & Work Experience for Level 2 PA are

    100 hours training and 3 months supervised work experience in using PA to be obtained either before the examination, or within 24 months after passing the exam.

    Once the 100 hours training have been obtained, the examination passed, and 3 additional months supervised work experience obtained within 24 months of passing the exam, PCN will issue certification.

    Note: Phased Array is an Advanced Level of Ultrasonic Testing; candidates must hold a current valid PCN Level 2 and 3 Certification in Ultrasonic Testing to be eligible for PCN Level 2 and 3 Phased Array examinations.
