DOWNLOAD EBOOK →The purpose of this document is to present a concise survey of the state of the art in advanced ultrasonic testing systems, techniques, and system components. Information presented is intended to give a practical overview of the types of ultrasonic nondestructive inspection apparatus presently in use and of relatively new techniques which are being applied to improve the capabilities of such systems. Computer retrieval facilities of the Nondestructive Testing Information Center (NTIAC) were used to search the open literature in ultrasonics and related subjects from 1968 through 1975. Technical uournals, conference proceedings, research reports, Department of Defense technical reports, and trade journals were included in the body of literature surveyed. This state-of-the-art survey includes discussions on (1) automated ultrasonic inspection systems for a variety of applications, (2) signal processing techniques as applied to ultrasonic inspection systems for a variety of applications, (2) signal processing techniques as applied to ultrasonic inspection, (3) ultrasonic imaging systems, including direct and holographic types, (4) methods of inferreing material properties from ultrasonic measurement, (5) special ultrasonic techniques (i.e., the Delta technique and stress enhancement of fatigue crack detection), and (6) ultrasonic inspection system components including transducers, scanning devices, and pulsers. Because of the magnitude of the subject covered by this survey, discussions of individual items are necessarily briefy; frequent references are made to the literature from which the reader may obtain detailed information.

DOWNLOAD EBOOK →Ultrasonic methods have been very popular in nondestructive testing and characterization of materials. This book deals with both industrial ultrasound and medical ultrasound. The advantages of ultrasound include flexibility, low cost, in-line operation, and providing data in both signal and image formats for further analysis. The book devotes 11 chapters to ultrasonic methods. However, ultrasonic methods can be much less effective with some applications. So the book also has 14 chapters catering to other or advanced methods for nondestructive testing or material characterization. Topics like structural health monitoring, Terahertz methods, X-ray and thermography methods are presented. Besides different sensors for nondestructive testing, the book places much emphasis on signal/image processing and pattern recognition of the signals acquired.

DOWNLOAD EBOOK →Ultrasonic testing is a relatively new branch of science and industry. The development of ultrasonic testing started in the late 1920s. At the beginning, the fundamentals of this method were borrowed from basic physics, geometrical and wave optics, acoustics and seismology. Later it became clear that some of these theories and calculation methods could not always explain the phenomena observed in many specific cases of ultrasonic testing. Without knowing the nuances of the ultrasonic wave propagation in the test object it is impossible to design effective inspection technique and search units for it realization. This book clarifies the theoretical differences of ultrasonics from the other wave propagation theories presenting both basics of physics in the wave propagation, elementary mathematic and advanced practical applications. Almost every specific technique presented in this book is proofed by actual experimental data and examples of calculations.

DOWNLOAD EBOOK →Ultrasonic testing (UT) has been an accepted practice of inspection in industrial environments for decades. This book, Industrial Ultrasonic Inspection, is designed to meet and exceed ISO 9712 training requirements for Level 1 and Level 2 certification. The material presented in this book will provide readers with all the basic knowledge of the theory behind elastic wave propagation and its uses with the use of easy to read text and clear pictorial descriptions. Discussed UT concepts include: - General engineering, materials, and components theory - Theory of sound waves and their propagation - The general uses of ultrasonic waves - Comprehensive lab section - Methods of ultrasonic wave generation - Different ultrasonic inspection techniques - Ultrasonic flaw detectors, scanning systems, and probes - Calibration fundamentals - General scanning techniques - Flaw sizing techniques - Basic analysis for ultrasonic, phased array ultrasonic, and time of flight diffraction inspection techniques - Codes and standards - Principles of technical documentation and reporting It is my intention that this book is used for general training purposes. It is the ideal classroom textbook. -Ryan Chaplin

DOWNLOAD EBOOK →As part of the on-going research activities related to ultrasonic inspection of welds, a review of available phased array automated ultrasonic testing systems has been conducted. As part of this review, a demonstration of the IntraSpect Phased Array system, manufactured by AMDATA was conducted at the FHWA NDE Center. The purpose of this equipment demonstration was to review the operational characteristics of this system and assess the system for possible use at the NDE Center.
