SCIENTIFIC-TECHNICAL SECTION

Smirnov I. V., Sidorov V. P., Zakharenko A. I. �Attitude position of the arc, deflected by the eigenfield

Research results of the arc altitude on the groove faces under conditions of root layer machine nonconsumable welding by an arc deflected by the eigenfield are described. Mathematical formulation of the arc heating spot centre position changes in time is given, as well as dependence allowing for calculating welding arch deflection angle from the electrode axis, considering distance from the current contact jaw to the electrode axis, welding current and current switching frequency.
Key words: argon arc welding, arc altitude position, magnetic field

Fedorenko G. A., Ivanova I. V., Sinyakov K. A. � Working the welding process in the shielding gas under the wind

Theoretical data and experimental results of the shielding jets formation and their behaviour in the blowing off air streams are considered aimed at designing welding process in the wind.
Key words: technological process, gas protection, torch, deformation, efficiency factor

Boudkin Yu. V. � Obtaining welded joints from dissimilar metals

Dissimilar metals and alloys weldability determination is based on the estimation of their bases interaction, at the same time effect of the primary alloying element is also taken into consideration if possible. Qualitative joint production and prevention of intermetallid formation is determined to a large extent by the dissolution and following diffusion of the refractory metals in the liquid steel.
Key words: dissimilar metals, welding, alloying elements, butt joint

Sakhno L. I., Sakhno O. I., Likhachiov D. I. � Engineering approach to analysis of the transformer winding discs critical thicknesses of the resistance welding machines

It is established that resistance welding machine�s transformer winding discs thicknesses growth higher than certain critical value causes loss increase and excessive consumption of the winding copper. An analytical calculation of this value is given. Relative units� application in analytic expressions considerably simplifies disc critical thickness calculation.
Key words: transformer, resistance welding machines, inverter power supply, disc critical thickness, surface effect, coil loss

Perevezentsev B. N., Kourmayev M. N. � Sn�Ag�Cu-based ecologically pure solder

A solder is developed, which does not contain such harmful component as lead and shows super performance property, at the same time processing behavior of the solder remain unchanging.
Key words: solder, environmental safety, mechanical strength

PRODUCTION SECTION

Kouvshinova N. N. � Energy-efficient technology of welding steel components

Development sequence of steel components welding energy-efficient technology is covered. Thermite charge optimal makeup is suggested and thermite welding special form is developed. Comparative cost analysis for steel articles patch work is performed.
Key words: deposit welding, reconditioning, defect, energy-efficient process

Korniyenko A. N., Litvinov A. P. � Circular joints plasma-arc welding in thing-walled cylindrical and spherical aluminium constructions

Plasma-arc welding technique is designed for the joints with technological bead necessary to fasten flanges in thing-walled large-sized cylindrical and spherical constructions. A high-temperature plasma-gas stream penetrating down to the bottom of the bath damages oxide film at welding aluminium products.
Key words: plasma-arc welding, aluminium alloys, oxide film, through penetration

Lebedev V. A. � Classification of the electrode wire feeders for welding equipment

Classification of the electrode and filler wire feeding devices for welding equipment is given taking into consideration complexity and technical feasibility.
Key words: wire, feeding, speed, modulation, regulation

Kovtunov A. I., Semistenov D. A., Chermashentseva T. V., Borodin M. N. � Wear-resistant coating formation features at deposit welding aluminium-magnum alloys onto steel

Argon-arc facing processes of the wear-resistant iron-aluminide-based coatings using filler wire of the aluminium-magnum system are studied. Conditions effect on the geometries, chemical composition and properties of the deposited bead are established.
Key words: argon-arc deposit welding, coatings, filler wire, wear resistance

Mchedlov S. G. � An apparatus for dry jet-abrasion surfacing of component parts

It is established that application of the apparatus for dry jet-abrasion surfacing of component parts maximum secure the operator from the dust at surface preparation before sputtering gas-thermal coating.
Key words: thermal spray coating, dust, jet-abrasion machining

ECONOMICS AND PRODUCTION ORGANIZATION

Davydova O. V. � Special features of the enterprises' accounts mutual settlement in crisis situations

Influence of some calculation methods, particularly commodities exchange operations, discharge of debt liabilities by debts offsetting, on financial activities of enterprises under crisis situation is considered.
Key words: enterprise, crisis situation, financial performance, mutual settlement
