SCIENTIFIC-TECHNICAL SECTION

Lasarson E. V., Schitsin Yu. D. � Department for welding production in The Perm National Research Polytechnic University is 50 years old

A history of the creation and formation of the department for welding production in The Perm National Research Polytechnic University is given.
Key words: university, department of welding production, scientific manpower

Krivonosova Ye. A., Rudakova O. A. � Structure influence of separated layers of steel 10�2�� welds on resistance to fatigue failure

The results of fatigue bend tests of multilayer welds of the steel 10�2�� are given. The quantitative parameters of resistance to fatigue � the duration of incubation period of the fatigue crack origin and the crack propagation speed in the period of stable development are identified.
Key words: arc welding, fatigue crack, weld

Trushnikov D. N., Belenky V. Ya. � Research of formation of secondary current signal in plasma at the electron-beam welding with electron beam oscillation

The research results of the formation of secondary current signal in plasma at the electron-beam welding with beam oscillation along across a butt are given. The analysis of the secondary signal performed by a synchronous storage method. It is established that the parameters of a function which is the result of secondary signal treatment by the synchronous storage method depend on a focusing mode.
Key words: electron-beam welding, oscillation, secondary current signal

Olshanskaya T. V., Trushnikov D. N., Belenky V. Ya., Mladenov G. M. � Influence of electron beam oscillation on formation of weld structure and properties

It is established that the using of electron beam oscillation has a direct influence on the process of primary and secondary structure formation of weld metal according to the changes of a weld shape.
Key words: structure and properties, oscillation, electron-beam welding

Sinani I. L., Schitsin Yu. D., Fomin I. B. � Ion-plasmous composition for soldering of titanium alloys

The present work sets as the purpose working out of layered composition Mo�Ni on titanic alloy OT4 with application non-polluting magnetron a method. The mechanism of formation of good connection in contact pair OT4�Mo at a stage of drawing of a covering is offered. It is shown that in the conditions of a temperature mode of the soldering of a layered composition (850 �C) occurs mutual diffusion penetration of materials that provide high quality of coupling in terminal pair OT4�Mo and Mo�Ni.
Key words: magnetron sputtering, diffusion layer, terminal pair, activation energy, adherence

Schitsin Yu. D., Kuchaev P. S., Schitsin V. Yu. � Plasma-arc metal cutting with reversed polarity direct and mixed gas supply

The present report describes the development and appliance experience of plasma-arc metal cutting with reversed polarity direct and mixed gas supply. There is shown high efficiency of plasma-arc metal cutting with direct-current reversed polarity using either manual or machine cut in workshop condition. It is significant that number of starts of constricted arc might be more than 1000 for nondestructive electrode efficiency.
Key words: plasma-arc cutting, cutting plasmatron, reversed polarity direct, mixed gas supply
