Key words: pulsed arc welding, I-groove, seam formation

Babkin A. S., Kruchanenko A. Yu. � Welding production CAD-tooling

A CAD-system for welding practices TEKHSAPR is work out. Its application will allow to improve quality of the welded structures, to raise labour productivity, reduce material losses, improve procedures discipline, shorten period of preproduction engineering.
Key words: welding production, CAD system, welded structures, automation

Yerofeyev V. A., Logvinov R. V., Nesterenkov V. M., Mazo A. B. � Equivalent heat source formation for strain analysis of constructions at electron-beam welding

A method of equivalent source power distribution is developed, which is based on inverse numerical solution of heat conductivity. A possibility of using an equivalent source to solve thermodeformative problems by MARC software is shown; it is sufficient to describe in a special subprogram motion of line of beam action within the finite-element mesh and to recount power distribution to the mesh parameters.
Key words: electron-beam welding, heat source, cross-section of seam, capacity

Lukin V. I., Rylnikov V. S., Afanasyev-Khodykin A. N., Timofeyeva O. B. � Diffusion brazing technology features of heat-resistant alloy ��975 and of casting monocrystalline intermetallide alloy ��-4� relating to blisk constructions

The problem of receiving high-strength brazing joints of heteronymic alloys: monocrystal intermetallic alloy ��-4� and deformed nickel superalloy ��975 is lighted in the article. The processes and behavior of solder and brazed materials alloying elements that are taking place during diffusion brazing in the seam and heat effected (near brazing seam) zone, are investigated.
Key words: brazing, solder, diffusion brazing, intermetallic alloy, deformed alloy, monocrystal alloy

Arkhipov P. P., Keremzhanov A. F., Silivanov V. N., Steklov O. I., Demin Ye. A. � Thermosensory control of pulsed laser welding

Thermosensory control results of solid-state-laser welded longitudinal and curved seams having different thicknesses and from different alloys are covered, as well as mathematical models, comparison results of visual optical and monitoring and of thermosensory control.
Key words: pulsed laser welding, thermosensory control, pentatechnologies

PRODUCTION SECTION

Titarenko V. I., Golyakevich A. A., Orlov L. N., Mosypan V. V., Babenko M. A., Telyuk D. V., Tarasenko V. V. � Reconditioning surfacing of mill rollers by flux cored wire

Mill rollers restoration techniques using new surfacing materials are considered and illustrated by examples of flux cored wire usage at enterprises.
Key words: reconditioning surfacing, rolling mill, rollers, flux cored wire

Mansurov V. V., Bogdanov V. V., Avvakumov Yu. V., Bykov A. N. � On the issue of welding electrode coating inhomogeneity

A methodology based on inhomogeneity estimate of values of growth formation duration and drop existence on the electrode tip is offered. It allows obtaining qualitative index for electrode compound homogeneity estimate; the index depends on evenness of binding material distribution in dry charge and of grain distribution of charge materials.
Key words: welding electrode, coating, electrode compound, charge, sputtering coefficient

Novosadov V. S. � Optimization of brazing thermal cycle of steels

Optimization research results of temperature-and-time brazing of austenitic (12�18�10�) and martensitic (06�15�6��-� (��16) and 03�12��-�� (��25)) structural steels widely used in heat exchanger production are covered.
Key words: brazing, structural steel, thermal cycle

Anakhov S. V., Pykin Yu. A., Shakurov S. A. � Structure functional design philosophy in electric plasma technologies

System attributes of functioning in electroplasma technologies are considered. Principles and the methods of plasmotrons and plasma technologies designing are generalized. It is emphasized on necessity to account the conditions of safe plasmotrons application.
Key words: plasmotron, plasma technologies, designing, method, principle, safety, efficiency, quality, system approach, optimization
