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
