Ultrasonic Inspection (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.
The Level I and Level IIA ultrasonic courses require no prior training or experience by the student, however, the balance of our ultrasonic courses do have specific training prerequisites. Training material is presented in a manner that promotes understanding and the ability to make immediate application. Basic courses are ideal for NDT trainees who must have Level I and II training in order to qualify for certification as well as facility personnel who are responsible for or oversee the application of testing or Quality Control/Quality Assurance, whereas advanced courses such as Phased Array (PAUT) and Time of Flight Diffraction (TOFD) are suited for the experienced UT technician wishing to further their career in this testing method.
Course Content
U2410 Basic Theory and Wall Thickness Level I.
This course is presented in a 40-hour classroom course and provides the absolutely essential theory required for the student to perform valid ultrasonic inspection. Fundamental concepts and terminology of ultrasonics and the mathematical relationships that exist between them are explored in depth. Instrument calibration, types of equipment, and basic ultrasonic application in the form of wall thickness measurements are fully covered. Ample time is allowed for technique demonstrations and hands-on lab exercises. Lecture notes, text book and necessary testing materials are provided.

U2411-WB UT Basic theory and Wall Thickness Level IIA . (Online or On-Site or by Special Scheduling Only) Because of the frequent need for certified ultrasonic wall thickness technicians without shearwave training or experience, we offer a special limited certification training course that is recognized by ASNT. The material covered is focused on wall thickness techniques using both digital readouts and A-Scan displays. We also cover information related to wall thickness testing of high temperature materials as well as techniques for obtaining accurate wall thickness readings through paint and other coatings.
