SCIENTIFIC-TECHNICAL SECTION

Ostsemin A. A. � Stressed state and strength of an inclined soft interlayer of mechanically heterogeneous welded joints with lack of penetration in the seam centre

The article presents estimation of static strength of the mechanically heterogeneous welded joints with lack of centre fusion. Stressed state of mechanically heterogeneous inclined butt joint with faulty fusion was studied. The suggested estimation procedure of static strength and plasticity of the mechanically heterogeneous welded joints allows to determine bearing capacity by introducing coefficient of mechanical heterogeneity, size of lack of penetration and inclination angle in the design formulae.
Key words: butt joint, soft interlayer, lack of penetration, force, stressed state, mechanically heterogeneity, contraction

Nafikov M. Z. � Formalized description of the welded joint formation at contact wire welding

The restoration of worn shafts by simultaneous one-side contact welding of two steel welding wire is shown as an efficient and productive process. Formal description of the process of welded joint formation in the solid phase is given. The resulted mathematical model can be applied in the process of restoring the worn shafts.
Key words: contact welding, steel wire, welded joint, formalized description

New equipment and technologies for low-frequency vibration processing of produce in engineering industry are considered. Design and specification of new equipment, methods of stress relief after welding operations, casting, machining, etc., as well as stress control equipment before and after processing are covered.
Key words: stress, low-frequency vibration processing, equipment, technology

Artemenko Yu. A., Fedyukin E. S., Gusev A. A., Neranov A. A. � Study of the surfacing processes of joint faces in turbine casing of nuclear power plants

Tests for resistance to peeling of chromo-nickel metal, which was surfased on carbonaceous steel by various technological options are carried out. Application of a way of a surface with simultaneous formation of a high-austenite intermediate layer allows to increase resistance to peeling at essential economy o a high-nickel alloy.
Key words: combined surfacing, erosive-resistant alloys, austenite intermediate layer

Yegunov A. I., Artemenko Yu. A., Konoreva N. A., Usikova N. Yu. � Designing an experiment at developing a process of coaxial laser gas-powder surfacing of an alloy of the Mo + NiCrBSi system

Experimental features of coaxial powder laser cladding alloy Mo + NiCrBSi. According to the results of the multivariate experiment based on indicators identified by the dissolution of iron in overlaid mode parameters of roller surfacing. Technological recommendations are developed.
Key words: laser, gaz-powder surfacing, planning of the experiment

Lukina N. F., Dementyeva L. A., Serezhenkov A. A., Chursova L. A. � Application of composite materials on the basis of glued prepregs in the constructions of components and aggregation of aeronautical engineering

The article shows function, advantages and application efficiency of the composite materials on the basis of glued carbon-filled and glass prepregs. Field of application of these materials in the product design for aircraft and space engineering is described.
Key words: glued prepregs, composite materials, forming technique, properties, application practices

Novosadov V. S. � Principal process features of soldering steels by composite solder of the system chromium�nickel�manganese

By an example of brazing heat exchangers from steel 12�18�10�, ��16 and ��25 the authors analyzed application efficiency of multilayer composite brazes of the Cr�Ni�Mn system. The brazed joints are full-strength to steel 12�18�10� in case of optimum brazing data, optimum relationship of coating thickness and sequence of application; such joints have high corrosion stability. When the elements of the composite brazing alloy are applied totally 60 micrometer thick, the spreading area is more than twice wider as compared to strip braze.
Key words: composite solder, steel soldering, soldered joints, uniform strength

ECONOMICS AND PRODUCTION ORGANIZATION

Bratukhin A. G. � CALS is an objective reality of competitive engineering industry

The content of the "Russian encyclopedia of CALS. Air-space engineering" is given.
Key words: CALS-technologies, air-space engineering, information technology

Kotelnikov A. A., Rodionova I. N., Alpeyeva E. V. � Economic estimate of the welding production elements

The article presents a list of welding production components and sections of business plan. A procedure of setting of proper output rates in the Delphi environment was developed, as well as computation technique of basic production assets, factor costs, shopfloor-wide expenses, production cost. The authors come to a conclusion that use of the Delphi environment diminishes error probability and significantly reduces execution time for production components� calculation.
Key words: welding production, business plan, programming environment, basic production assets, production cost
