The book "There is no future without history" by the General Director of the ECHOPLUS

Several years have passed since the publication of the second edition of the book. During this time, important changes have taken place in the life of our team and in my life. Firstly, thanks to her, I learned a lot about my parents: mom and dad, about new relatives. So there was a new chapter about them. Secondly, I decided to tell an instructive story about how I built my house without having any funds or experience in construction. It also includes a number of new stories about the most interesting events that happened to me and around me with an analysis of the results achieved. Thirdly, I wanted to tell you about some, as it seems to me, interesting people with a difficult fate. Over the years, people dear to me have passed away, including Anatoly Konstantinovich Gurvich – at the age of 91, Viktor Grigorievich Shcherbinsky – at the age of 84. I decided to supplement the book with their portraits. Finally, fourthly, readers have sent me quite a lot of laudatory reviews, and I wanted to share them. Some sections have also been modified and supplemented with photos.

I. N. Ermolov. Life, science and flaw detection stories

Igor Nikolaevich has educated about thirty candidates and doctors of sciences. His students scattered all over the former USSR, and there are them in Europe. And his theory of the acoustic path has made its way without exaggeration all over the world. This book is a tribute of love and respect to a great scientist and a wonderful person.

Ultrasonic flaw detection for 25 years. Anniversary collection of works of the SPC ECHOPLUS

The collection includes the most interesting works performed by the team of the ECHOPLUS in recent years. Simultaneously with the development and use of automated ultrasound systems with coherent data processing, the following are presented works devoted to the research, development and application of devices with phased antenna arrays. New electronics, scanning systems, and image quality improvement algorithms are described. The basic principles of the construction of control methods using such systems are considered. The question of the ratio of radiography and ultrasound in non-destructive testing is investigated. It is shown that coherent automated ultrasonic inspection in some cases gives results no worse, and in combination better, than radiography. The experience of using a computer programming program is given. modeling of tasks of the "CIVA" ultrasound control center for the development of ultrasound control techniques.

AUTOMATED ULTRASONIC INSPECTION OF HIGH-RISK OBJECTS (ANNIVERSARY COLLECTION OF WORKS OF THE ECHOPLUS COMPANY

The collection of articles includes the main works of the ECHOPLUS Company team dedicated to the creation of automated ultrasonic control systems for hazardous industrial facilities. It is noted that the use of coherent data processing methods in automated ultrasound systems made it possible to make the transition from flaw detection to flaw detection with access to the evaluation of the residual resource. The new technology has found wide application in the leading sectors of the national economy, primarily in the nuclear power industry, Gazprom, Transneft, Russian Railways. The results of the development of Augur series systems and their application in these areas are presented. It is shown that the use of automated systems gives a significant technical and economic effect.

Ultrasonic flaw detection for 30 years. Anniversary collection of works of the SPC ECHOPLUS

The collection includes the most interesting works performed by the team of the ECHOPLUS Company in recent years. Simultaneously with the development and use of automated ultrasound systems with coherent data processing, the works devoted to the research, development and application of devices with phased antenna arrays are presented. New electronics, scanning systems, and image quality improvement algorithms are described. The basic principles of the construction of control methods using such systems are considered. The question of the ratio of radiography and ultrasound in non-destructive testing is investigated. It is shown that coherent automated ultrasonic inspection in some cases gives results no worse, and in combination better, than radiography. Examples of the use of data visualization tools and automation of ultrasound control are given. A new manual ultrasonic flaw detector "AUGUR-ART2020" is presented, which implements all modern and popular developments.
The experience of using the computer simulation program for the tasks of the CIVA ultrasound for the development of ultrasound control techniques is given.

ULTRASONIC METAL FLAW DETECTION USING HOLOGRAPHIC METHODS

The issues of theory and practice of ultrasonic flaw detection based on the application of digital acoustic holography algorithms in relation to the operation of high-risk facilities are considered. The features of various algorithms for obtaining a coherent image are given, including:  projections in spectral space, angular spectra, reference holograms, etc. The developed Augur series equipment and its modifications in relation to various control objects are described in sufficient detail. It is shown that the information about the type and size of defects obtained during holographic control is sufficient to assess the residual resource of the object. Based on the results of numerous metallographic studies, the error of measuring the size of defects, which is  1.5 mm, is estimated.  More than 10 years of experience in the use of Augur series systems, primarily at nuclear power facilities, is given; signs of types of defects and algorithms for automatic determination of their parameters are formulated. Methodological foundations of holographic control of a wide range of welded joints have been developed, which allowed the creation and certification of 13 specialized techniques. Of interest are systems for the diagnosis of wheel sets of railway cars using digital acoustic holography, in which a specially developed program for determining the residual resource is used. Promising methods of increasing the resolution and quality of defect images are described. It is intended for developers and specialists in the field of diagnostics and operation of high-risk facilities, for training centers for specialists in the field of non-destructive testing.

CALCULATIONS IN ULTRASONIC FLAW DETECTION (short reference)

The reference book is intended for specialists in narrow-field engineering with qualifications not lower than the second level, developing control methods and converters. The main attention is paid to physical control issues. Of the methods, the echometode is considered in detail, since it finds the greatest use.The values are expressed in SI. In space-time problems, more convenient derived units are used: for time – mks, for frequency – MHz, for distances – mm.
