Nondestructive Testing (NDT) is practiced in nearly every industry. Its application ranges from common routine inspections, to Structural Health Monitoring (SHM), incident and damage assessment, and failure analysis. The American Society for Nondestructive Testing (ASNT) defines different categories of NDT and classifies them as “Methods”. Each fundamentally different from the other, based on the principles of science involved. For example, Ultrasonic Testing (UT) is a different method from Radiographic Testing (RT) or Infrared Thermography (IRT). Each method in turn, comprises a variety of techniques, which represent different approaches of performing the inspection within the same method. For examples, the Pulse-Echo (PE), Through-Transmission (TT), water jet, air-coupled are all different techniques of UT.
The physics and engineering aspects involved with all these methods and techniques are broad and can be overwhelming. They span over a variety of disciplines such as acoustics, optics, radiation, electromagnetics, thermal properties, dielectric properties, mechanical properties, materials science, chemistry, data acquisition, signal processing, and many more. Therefore, it is not likely to find one expert in all methods on NDT. Most Level-III inspectors (the highest level of certification) are experts in a few methods but have a broad knowledge of the remaining methods. Lack of broad knowledge or a large variety of techniques (tools) in one’s disposal often leads an inspector to use an inferior technique or wrong method altogether when performing the inspection.
The scientific concepts behind each method can be very complex. Aside from performing routine inspections, knowledge of these concepts becomes necessary before developing a new technique, understanding its capability, or being able to develop reasonable expectations of the proposed technique. The purpose of this course is to provide an overview of the different NDT methods and techniques, and the different tools available in the NDT world. It provides the most essential concepts that helps understand the capability of each technique. Examples of common applications are given along with others where advanced techniques are used to solve challenging problems.
- Program managers, chief engineers, and other upper-level staff who would like to become more familiar with NDT and the different approaches available toward solving non-routine problems
- Design engineers, structure & failure analysts, materials scientists, and other engineering staff who would like to expand their knowledge in the area of NDT
- Non-NDT staff who would like to become more proficient in their interaction with NDT staff and in dealing with NDT issues
- NDT personnel who would like to expand their knowledge toward other NDT techniques that they are not familiar with
- Obtain a basic knowledge about the different NDT methods and techniques
- Understand how the inspection criteria are defined and how to pick the appropriate NDT technique accordingly
- Become aware of the tools available for NDT and be able to select the appropriate one
- Have reasonable expectations for what an NDT technique can offer, based on its advantages, limitations, and validation method
- Become aware of some common applications and some advanced approaches for solving challenging problems
- To incorporate concepts such as “design for inspetability”; understand the probability or challenges of inspecting any given hardware; and recognize the relevance or validity of an NDT technique to the intended purpose of inspection
Coordinator and Lecturer
Shant Kenderian, PhD, Fellow of the American Society for Nondestructive Testing (ASNT)
Manager, Materials Physics and Nondestructive Evaluation Section at The Aerospace Corporation, El Segundo, CA with a BS and MS degrees in Manufacturing Engineering, Kenderian began his career as a manufacturing engineer in a number of industries including apparel, cosmetics, jewelry, and aerospace. In 2002, he obtained an MS and PhD in Materials Science and Engineering from the Johns Hopkins University in Baltimore, MD. His studies were focused on advanced NDT methods for materials characterization and resulted in two US patents on using a laser-air hybrid ultrasonic technique for railroad inspection applications. He also holds a European patent in this field. He is the author of numerous refereed journal publications and conference proceedings, serves as a reviewer on a number of technical journals, and is the author and technical editor of a number of NDT related books. Dr. Kenderian served six years on the Board of Directors for ASNT, two years as the chair of the Research Council, and as the technical program chair for several national and international conferences.
In the aftermath of the Space Shuttle Columbia disaster, he joined the NASA Super Problem Resolution Team (SPRT). During the first two years, the SPRT engaged in an investigation to develop inspection methods for the External Tank (ET) Sprayed On Foam Insulation (SOFI) and a number of other tasks, which ultimately lead to the return to flight of the grounded shuttle program. In 2004, he held a Sr. Engineer position with Jet Propulsion Laboratory, and in 2005 he became a Member of the Technical Staff (MTS) with The Aerospace Corporation, where he currently manages the Materials Physics and NDE laboratory. As an FFRDC, The Aerospace Corporation is tasked to support the USAF space program. The Materials Physics and NDE laboratory is equipped with a wide range of advanced NDT techniques and staffed with a strong team of experts. The team is routinely tasked with problems deemed challenging or, at times, unsolvable and it has had a remarkable record of success.
Dr. Kenderian has been the recipient of numerous corporate awards by The Aerospace Corporation, Lockheed Martin, and NASA. He is also the recipient of the ASNT Fellowship Award, Outstanding Paper Award, Research Council Innovation Award, and Fellow Award.
