ULTRASONIC TESTING (UT)

Ultrasonic Testing (UT) uses high frequency sound energy to conduct examinations and make measurements. Ultrasonic inspection can be used for flaw detection/evaluation, dimensional measurements, material characterization, and much more. Although there are a number of technologies employing ultrasound, the simplest explanation of what happens in this method is that sound energy is introduced via a transducer and propagates through the materials in the form of waves. When there is a discontinuity (such as a crack) in the wave path, part of the energy will be reflected back from the flaw surface. The reflected wave signal is transformed into an electrical signal by the transducer and is displayed or recorded in a variety of ways. Both surface and subsurface defects can be detected making ultrasonics a volumetric testing method. Applications vary in complexity from very small, hand-held manual units to very large, sophisticated automated systems. This method is used to inspect a variety of product forms including castings, forgings, and weldments. The structural steel, automotive, petrochemical, power generation, and aerospace industries are a few examples that utilize ultrasonic inspection.

COURSE DESCRIPTION

A course for those who already have basic understanding of the techniques of ultrasonic inspection and are wanting intensive instruction to improve their knowledge and increase their experience. The course is suitable for candidates who are wishing to progress towards any of the examination qualification. The course has a high practical content.


WHO SHOULD ATTEND

This course is opened to all participants, in particular NDT personnel, supervisors, NDT trainers, contractors and researchers and those who are interested in Ultrasonic Testing technique.
