Development of industry demands better performance of equipments and devices than ever. The property of material used to produce the equipments is the precondition to ensure the quality. As equipments are usually required to be integral during the quality inspection, non-destructive testing (NDT) plays an increasingly import role in modern industry quality control. Different NDT methods are introduced and analyzed. The mechanism of ultrasonic exciting is described. After the ultrasonic is excited, the vibration signal can be detected by transducer or optical method which are then illustrated. In the section of development of laser ultrasonic technology, contributions made by various researchers in theoretic development, experiment, simulation and application are introduced and the corresponding content of the researches as well. The conclusion and the outlook of laser ultrasonic technique is made at the last.

A comparative study of the mechanical properties of the extruded and flattened nanostructured composites Al-C60 has been made using two different methods of destructive and non-destructive testing: tensile and compression macro-tests and sub-micron range sclerometry (scratch test). Direct correlation was found between the dominant types of deformation during scratching and the type of “stress-strain” dependencies. The results are useful for understanding the extrusion process and quality control at different load scale.

The history of capillary control began in the 40s of the last century for the needs of the aerospace industry. Currently, the cost of quality control in the aerospace industry is up to 12 - 18% of the cost of products. Similar amounts of expenses in the nuclear and defense industries are not lagging behind other industries. For example, for the control of welded joints of oil and gas pipelines of large diameter and considerable length, the labor costs for inspection reach 10% of the total labor costs. Capillary quality control method is based on the ability of indicator liquids (penetrants) to penetrate into the cavities of surface defects (discontinuities). Over the 70 years of its existence, the capillary method of control has not undergone fundamental changes, and its principles have remained unchanged. In international practice, the abbreviated designation of types of non-destructive testing (AWS) is adopted, and the control with the use of penetrating liquid denoted RT. This method is applicable to the detection of all types of surfacedead-end and through defects, such as cracks, delamination, leaks, in products made from any non-porous materials, including glass, ceramics, plastics and other non-metallic materials. The analysis of the capillary method of nondestructive testing of the surface of a solid body is carried out, the possibilities and ways of its improvement are indicated. The method of the capillary method of non-destructive testing of a solid surface, the physics of the method and its implementation are considered in detail. It is shown that the wetting ability and spreading are important characteristics of capillary control fluids; therefore, they must be evaluated and analyzed when developing new ones, choosing or comparing known capillary flaw detection materials. The possibility of using the Rebinder effect to improve the capillary method of non-destructive testing of a solid surface has been proved. A refined method of capillary defectoscopy is proposed by taking into account the wetting ability, density, viscosity and evaporation of a liquid, which makes it possible to make an optimal choice of liquid to ensure high efficiency of surface (capillary)control. An improved method for assessing the wetting ability of liquids is proposed, which makes it possible to evaluate the wetting ability of liquids by the size of the spreading spot of their droplets, taking into account the influence of density, viscosity and evaporation of liquids intended for capillary flaw detection (penetrants).

Currently, in various industries (engineering, aircraft, energy, etc.) the issue of product quality assurance and control is particularly acute. This is due primarily to the ever-increasing requirements for increasing reliability with increasing loads on products, which entails the strengthening of technical standards. The issue of quality control for rocket and space technology products is especially relevant. Modern power structures of rocket and spacecraft made of polymer composite materials, and especially the body of solid fuel rocket engines (SFRЕ), are multilayer packages of various polymer-composite materials (PKM), obtained and interconnected in the process of manufacturing the body. The efficiency of SFRЕ depends on the quality of the formation of PKM in production conditions. The most important issues are the implementation of production quality control of composite structures, the reliability of control results and the ability to automate the control process. The article presents an automated system of non-contact ultrasonic non-destructive testing, which allows to control the stability of the technological process of forming the composite material of the wall of the SFRЕ body and, if necessary, to adjust it. The probability of detecting zones of anomalous violation of the integrity of the wall material of the SFRЕ housing is carried out due to adaptive algorithms, digital systems of multilevel matrix processing and optimal filtering of the received signals. The automated system of contactless ultrasonic non-destructive quality control of SFRЕ cases allows to register conditions of scanning and control for more visual representation of the defectogram in the expanded look of the case of a product in the course of control and at documentation of its results. The presented results of work on the development of an automated system of non-destructive testing of the integrity of the buildings of the SFRЕ type "cocoon" confirm the possibilities of practical implementation in production.

The purpose of the research consists in improving the theoretical basis for non-destructive quality control methods in the context of digitalization and an active transition to Industry 4.0. The methodology used by authors include the consideration of the logistics network digital twin, as well as globalization of markets and ever-increasing global competition in all areas. The article discusses non-destructive quality control methods based on the process of modeling digital twins and the authors’ approach proves the advantages of just such an innovative concept of expanding the definition of logistics network digital twin in comparison with the traditional methods of non-destructive quality control. It could be shown that this approach eventually leads the ability of industries to switch to digitalization of their processes. Saying precisely the improving of the quality control methods could be treated as digitalization of their supply chains, reflecting the entire product life cycle. We have displayed a digital supply chain, which includes the method of non-destructive testing, like a digital twin. The main difference between the digital supply chain and the traditional supply chain is noted. The ideas of large audit companies such as Gartner’s, Siemens and Deloitte are analyzed. What are the benefits of using a digital twin as a non-destructive testing method? All participants of this digital supply chain receive their benefits in terms of digitalization and market competition.
