International School of Aerospace NDT Limited
Ultrasonic Inspection of Aerospace Structures and Components
(80 hour/10 day Course)
This Level I/II course satisfies the syllabus requirements of ASNT-CP-189, SNT-TC-1A, NAS 410, BS EN 4179, PCN and ISO 9712. The course is suitable for engineering inspectors at all levels of experience who require formal training and a qualification in this subject.
The training programme covers 50% theory and 50% practical application allowing the student time to obtain a good foundation in this method of NDT by practicing a large variety of inspection techniques under the supervision of qualified instructors using the latest inspection equipment.
The course comprises:
- Introduction to ultrasonics, nature and transmission of sound application.
- Methods of generating and receiving energy.
- Types of transducers with descriptions of different elements.
- Modes of travel of ultrasonic energy in a material.
- Distribution of sound from transducers.
- Calculations regarding the beam characteristics of various transducers.
- Ultrasonic sound energy reflection from material interfaces.
- Calculations relating to the amount of sound energy reflected and changes in refracted angles due to differing acoustic velocities in materials.
- Main component parts of test equipment.
- Types of test equipment and different ways of displaying ultrasonic information.
- Factors affecting ultrasonic resolution and sensitivity.
- Test equipment calibration and performance checking.
- Immersion scanning and setting-up procedures.
- Sizing of discontinuities using common procedures.
- Reparation of technique and report writing procedures with emphasis on relevant specification interpretation.
All students are continuously assessed during the course by homework and progress tests together with a theoretical and practical end of course examination.
At the end of the course the students can take approval examinations in Ultrasonic Inspection at Level I, II or Level III to SNT-TC-1A, NAS 410 or BS EN 4179 in accordance with their company written practice.
International School of Aerospace NDT also acts as an outside agency providing Level III services as defined in the aforementioned documents.
