Chunguang Xu, professor,doctoral supervisor of School of Mechanical Engineering of Beijing Institute of Technology (BIT), the director of Key Laboratory of Fundamental Science of Advanced Machining of BIT, Prof. Xu was elected as Vice-chairman of 20^th world conference on Non-Destrctive Testing(WCNDT2020), committee member of Word Federation of Nondestrctive Evaluation Center (WFNDEC), Executive Chairman of IEEE Far East NDT Conference (IEEE FENDT),Vice-chairmen of the Division of Testing Acoustics of Acoustical Society of China, Fellow of Chinese Institute of Electronics (CIE), Director of Chinese Society for Measurement. Prof. Xu currently serves as a Guest Professor of China Academy of Engineering Physics (CAEP), Adjunct Professor of Pusan National University, Korea, Adjunct Researcher of Tokyo Institute of Technology, Japan.

Prof. Xu is the pioneer of low-stress manufacturing technology. Prof. Xu created the theory and technology of in-situ quantitative non-destructive testing and deformation control of internal residual stress of components, realized a pioneering leap in deformation control of components during processing, and solved the key problem of manufacturing quality and service reliability of high-tech equipment in China's key project fields. Prof. Xu has undertaken and completed more than 40 scientific research projects, including 1 Key Research and Development Project of The Ministry of Science And Technology, 2 key projects of The National Natural Science Foundation of China (NSFC), 1 Foundation Strengthening Project of the Military Science and Technology Commission, and 2 Major Projects of National Science and Technology. Prof. Xu led the formulation of 1 international standard, 37 national industry and enterprise standards, authorized 12 international invention patents, 68 national invention patents, published 7 monographs, and published more than 300 academic papers.

Prof. Xu created the low-stress manufacturing system technology, including low-stress welding, low-stress additive, low-stress cutting and low-stress casting systems, which systematically realized a revolutionary

leap in the ability to maintain the accuracy of processed components. Prof. Xu proposed a balance control model of component residual stress during processing, which solved the problems of deformation and cracking control such as weak rigidity aluminum alloy casting box processing, large crankshaft heat treatment, energetic material solidification, rocket cabin welding, and missile shell addition. This problem has increased the machining accuracy of components by 5 to 10 times, and improved the performance and precision maintenance capabilities of multiple high-end equipment components. Prof. Xu proposed a multi-dimensional high-frequency ultrasonic attenuation compensation model, which solved the long-term problem of inaccurate measurement of defects in core components of high-end equipment such as adiabatic shells, missile aluminum alloy shells, and aeroengine blades, making the detection resolution better than 0.05 mm, leading international technical indicators. Prof. Xu also innovated the in-situ detection and control technology of material properties, established the technical standard system and national benchmark for ultrasonic detection and regulation of residual stress, and serialized the in-situ detection and regulation of residual stress in large components.
