This course will provide participants the theory lectures and practical training with a preliminary understanding of Acoustic Emission (AE) as per the ASNT Recommended Practice No. SNT-TC-1A for Personnel Qualification and Certification in Nondestructive Testing.
This course is designed to provide participants with a detailed and up-to-date overview of acoustic emission testing. It covers the principles, characteristics and sources of acoustic emission; the wave propagation, Kaiser & Felicity effects and Felicity ratio; the AE wave using sensors, instrumentation and signal processing; the cables, signal conditioning, signal detection and source location techniques; the acoustic emission test systems and accessory techniques; and the acoustic emission test techniques, equipment calibration, setting up for test and loading procedures.
During this interactive course, participants will learn the data display, noise sources and pre-test identification techniques; the precautions against noise, data interpretation, evaluation and reports; the codes, standards and procedures covering guide-type standards, standardized/codified acoustic emission test procedures and user-developed test procedures; and the proper applications of acoustic emission testing for laboratory studies (material characterization) and structural applications.
Sample Questions for general examinations will be presented in the question booklet C that was obtained from ASNT headquarters. Participants will further demonstrate familiarity with and ability to operate the necessary equipment for AE, record and analyse the resultant information to the degree required as well as test flawed specimen and component and analyse the results of NDT as part of the practical training.
At the completion of the course, participants will be appearing for a Level I exam. Each candidate will be a ‘Certified ASNT NDT Level I in Acoustic Emission Testing’ upon successfully passing the examination with a minimum passing composite grade of at least 80 percent (%).
