Yegorov N. I., Yemelyanenko A. A. — Investigation of the effective diffusion coefficient of hydrogen under conditions of thermal cycle of welding

Research facility was made. It helps to develop a method of measuring the effective diffusion coefficient of hydrogen in the case of thermal cycle of welding. Dependences coefficient of the temperature were investigated for different structure classes of the steel: ferrite-pearlite, martensite, bainite, martensite-aging and austenite. These dependences reflect the peculiarities of chemical composition and structural transformations in the conditions of welding.
Key words: welding, steels, effective diffusion coefficient of hydrogen, thermal cycle of welding

Burak P. I., Rudobashta S. P. — Coolant rate optimization for electrocontact welding

The technique of definition of the expense of a cooling liquid for electrocontact welding is offered. The expense of a cooling liquid for cases of electrocontact welding of a steel tape 50ХФА to the cylindrical sample from a steel 45 through an intermediate layer from metal powder Ni3-00-02 and Stemet 1301 is calculated. Reliability of the received values of the expense of a cooling liquid is confirmed high прочностными by characteristics of connected materials.
Key words: expense, cooling liquid, electrocontact welding, criterion, factor, material

Dragunov V. K., Ryzhkin R. A. — Nitrogen microsupply effect on the welded joints’ formation at electron-beam welding

The features of the electron-beam welding (EBW) with a supply of a nitrogen into the weld pool are considered. The atmosphere effects on the focusing of the electron beam and the depth of penetration are shown. The results of experiments are given, the dependencies of the chemical composition of weld metal and mechanical properties of welded joints on the amount of the supplied nitrogen are determined. The advisability of the nitrogen doping austenitic heat resistant steels welds in the process of EBW in order to increase the hot cracking resistance of the weld metal is suggested.
Key words: electron-beam welding, nitrogen microsupply, depth of penetration, electron beam focusing, mechanical properties

Starostin H. P., Danzanova Ye. V., Sivtseva V. V. — Mathematical modelling of polyethylene tubes low-temperature electrosocket welding

It is suggested to consider phase transition behaviour in the temperature range when simulating heat process at welding polyethylene tubes for gas pipelines. Comparison results of the theoretical time dependencies of temperatures and experimental data are given, and effectiveness of this approach for temperature field dynamics determination in the welds is shown.
Key words: welding, phase transition, polyethylene, temperature, melting, crystallization, socket,Stefan problem, smoothing of coefficients

Key words: activating flux, welded joints, laser welding


Yunin I. Yu., Feofanov A. N., Kapitanov A. V., Mitrofanov V. G. — Information analysis systems for industrial plant management

One of the most important tasks of the industrial plant scheduling is actual data extraction from the accounting systems using data warehouse. The latter gives an opportunity for constructing reporting forms, multivariate analysis with different level of detailing, graphic representation of information, automatic deviation computation. The above mentioned functions allow using stored in the warehouse information for a better накопленную в хранилище информацию для лучшего plant management control and business understanding. Analytical reports may be run over in different layout and by many devices: as a WEB-page from computer and mobile equipment, as spreadsheets, as formatted report with strictly settled order.
Key words: analytic control system of production profitability, manufacturing automation
