(ASNT: SNT-TC-1A: 2011)

  • course description:

    This course covers history and development of ultrasonic testing method, principles of the test and the test equipment, importance of calibration. Students are trained to select UT techniques and test settings, equipment calibration, conduct tests, interpret and evaluate test results with reference to standards, and prepare test report.

  • course learning outcomes:

    At the end of the course, the participants will be able to;
    - Understand Basic operation of a pulse echo system; Pulse length and considerations for penetration and resolution requirements.
    - Understand Definition of penetration and resolution; pulse damping; Pulse repetition frequency; the piezoelectric phenomenon; The "A" scan presentation, Basic design and operation of a general purpose ultrasonic flaw detector.
    - Understand Basic design and operation of transducers; Types of waves and their characteristics; Refraction and mode conversion.
    - Understand Practical consideration of sound velocity; Acoustic impedance and practical considerations.
    - Understand Refraction index; Beam physics; Review of the basic operation of an immersion testing facility; the advantages and disadvantages of the techniques; Focus transducer technology; to calculate water path distance.
    - Understand Horizontal linearity/vertical linearity; near surface resolution/far surface resolution; sensitivity/ signal to noise ratio;
    - Draw Distance Amplitude Correction (DAC);
    - Evaluate flaws for type of defect.
    - Interpret results based on ASTM / ASME standards and specifications.
    - Interpret the Company Procedure to perfor acceptance/rejection.
