In this thesis two-parameter stethoscope was developed for controlling rods of non-ferromagnetic materials with a diameter of 34-35 mm. For example, samples from bronze and duralumin were used.

In the first section were presented theoretical information of eddy current control, two-parameter control, as a kind of multi-parameter control. The theoretical data on types and species of eddy current converters are described. Also, such methods of signal processing as amplitude, phase and amplitude-phase are described.
In the calculation part of the work presented calculations of the eddy current converter itself, as well as its work in two modes: the first - at high frequency to control the diameter of the OK, the second - at low frequency, to control the electrical conductivity OK. The chosen method is substantiated, and graphs are given that prove that the chosen method is the most correct one. The third part - design and technological describes the technical characteristics, and the principle of this device. The block diagram of the device is given, and the functional scheme is developed. This appliance meets all the delivered tasks.

In the diploma project, a research was carried out on microcurrent NK and the search for defects in riveting compounds. In the first section was given an analysis of the object of control and the formulation of the problem of study in which were considered: types of riveted joints, types of rivets, the use of rivets. The second section deals with general information about the vortex current type of non-destructive control. The third section reviews the structures of the WWW and the work of the VSD, the calculation of the overhead transformer GSP, the description and calculation of the main elements of the VSD

The purpose of the project is to design a device based on the TOFD method, which would be suitable for a set of tasks (control welded joints to connect)
with a wall thickness of 15 to 50 mm.

In this work, a device for controlling welded joints of cisterns of large diameter or metal sheets based on the TOFD method was developed. Nowadays, more and more UDC control is taking place in such fields as aircraft construction, railways, chemical industry, NPP reactors, etc. Therefore, the requirements for quality and speed of inspection are coming to the fore. The diffraction-time method is united in itself the speed of control and the high probability of detecting a defect. For this method, a functional diagram of the device was developed, the scanner itself was designed on which it was placed, and by which the converters are moved along the OK.

The main purpose of diploma project of an educational level of bachelor, is the development of an industrial thermal imaging camera, for its use in conducting non-destructive control in the production. In the diploma project the research of existing technologies is carried out, the choice of the detector of infrared radiation is carried out, based on the conditions of use of the thermal imaging camera, the development of the optical scheme and the electrical path for the operation of the infrared radiation detector is carried out. The purpose of the diploma project is the development and calculation of parameters of the thermal imaging camera, development of principle electric circuit scheme, development of a functional scheme, and a description of the principle of the scheme. In the graphic part of the project is represented an optical scheme, an principle electric circuit diagram and an assembly drawing, as well as a functional scheme. Drawings of details of the optical scheme are developed.

This diploma project consists of 63 pages, 23 illustrations, 30 formulas, 21 literary sources. Key words: ultrasonic control, noise meter

In the diploma project, the study of the principles of operation of various  types of devices for measuring noise. Structural and functional diagrams are made. A schematic diagram and printed circuit board based on shredders were developed. On the basis of the performed calculations an experimental installation was developed.
As a result of the study, a type of instrument was used to measure noise, or rather a noise meter.
