Coated electrode burning-off rate determination at current-modulated manual arc welding. Knyazkov A. R, Dementsev K. I., Knyazkov V. L. P. 3�7.

Effective by-electrode voltage drop determination methods. FlpeflJioxeHa at current-modulated coated-electrode welding considering heat power expenditure allowing for calculating coated electrode burning-off rate are suggested.

Toroidal vortex characteristic study in protective jet under isothermal conditions. Fedorenko G. A., Zoob-koR. V. P. 8�11.

Characteristic research results of the toroidal vortex, lightened and protective jets under isothermal conditions are covered.

Resistance spot welding of the high-strength steel over the new antirust coat. Lookin V. L, Kovalchook V. G., Kondrashov E. K., Malova N. Ye., Golev Ye. V. P. 11�16.

Optimum contact spot welding conditions on the anticor-rosive coat are developed, which allow to obtain for the 30X�CH2A and X15H5�2T steels welded joints with shear and pull test breaking load not less than 0,9 as compared to the breaking load of uncoated welds, irrespective of curing time (up to 24 hours) and storage method before welding.

Modelling of the compensating device functioning jointly with contact welding sets. Glibin Ye. S., ShevtsovA. A. P. 17�21.

Operating conditions for bucking out systems jointly with contact welding machine are determined. A module of static compensator and capacitor-bank-based compensator is suggested for partnering in the bucking out system. Simulation results of the resultant bucking-out system operation in the Simulink system are given.

Coating quality control at component restoration and strengthening by electrocontact welding. Latypov R. A., Molchanov B. A. P. 21�28.

It is established that main prerequisites for quality management of coating and its joining to the base at components' restoration and strengthening by electrocontact welding are predeformation of the cold welded-on metal, welding zone protection, microrelief creation on the component surface, application of the powder interlayer. Compact and powder material electrocontact welding mathematical models are designed, which allow for coating structure and heat-affected area forecasting.

Innovation techniques of the welding joints quality diagnostics of the large-size constructions. Tazetdinov R. G., Kazakov V. A., Novikov O. M., Persidsky A. S., Baranov-sky A. V., Khasyanov B. A. P. 29�33.

Possibility of the X-ray diffraction method application to determine residual welding macro stress and dimensions of the softening areas, conditional on welding of large-size aluminium constructions is considered. Designed equipment and research results are described.

The CB-08F2C-C core wire to weld in gas mixture based on argon and carbonic acid. Soorkov A. V., Bas-takov L. A., Kipiani P. N., Volobuyev Yu. S., Yakovlev V. V. P. 33�37.

Developed wire C�-08�2C-C application appropriateness instead of wire C�-08�2�-C to weld in mixture containing 80 per cent of Ar + 20 per cent of CO2 is substantiated. Weld metal, obtained from the wire C�-08�2C-C application, has higher strength and plastic properties, as well as higher impact strength at low temperature and high resistance to high-temperature cracking.

Analysis of the rail-welding fabrication in Russia and abroad. Kalashnikov Ye. A. P. 37�49.

An analysis of rail-welding fabrication in Russia and abroad (in Japan, USA, France, Sweden, etc.) is carried out. Development of majors, supplying railways with ray-welding equipment, materials and manufacturing processes are covered. Positive moments and shortcomings of the "RZhD" JSC track facilities are shown. Ways of improvement of the domestic rail-welding industry are considered.

Porosity effect on the properties of the coatings obtained by plasma spraying. Simma L. I. P. 49�51.

Research results of the plasma-spraying coat porosity dependencies on technological factors allowing to develop sputtering processes of coat of various purposes are covered.

Welding aerosol as the main factor, influencing welder's safety of work, llyaschenko D. P., Grishaguin V. M. P. 51�54.

Hygiene and sanitary conditions for welding fabrication at manual arc covered-electrode welding are considered. Major factors, causing welders' occupational diseases are established. Existing welder's protective equipment from welding aerosols is given.
