SCIENTIFIC-TECHNICAL SECTION

Sarayev Yu. N., Bezborodov V. P., Grigoryeva A. A., Golikov N. I., Dmitriyev V. V., Sannikov I. I. � Residual stress distribution in welds of steel 09�2� by adaptive impulse arc welding methods

Research results of the influence of adaptive impulse arc welding conditions on mechanical properties and residual welding stress distribution of the welded joints of plates from the low-alloy steel 09�2� are described. It is established that under pulse welding conditions impact resistance of the weld metal at negative temperature is higher as compared to steady-state conditions and compressive residual welding stress is revealed.
Key words: welding, low-alloyed steel, mechanical properties, impact strength, residual welding stress

Lomberg B. S., Mazalov I. S., Bykov Yu. G., Dokashev V. V. � Special features of fabrication technique of welded ring construction from high-strength alloy ��172

An effective technology of automated microplasmous surfacing by cobaltic stellite is developed. Thorough metallurgical study allowing for grounded selection of optimum process variant is carried out.
Key words: microplasmous surfacing, turbine blades, macro- and microstructure

Terentyev Ye. V., Dragunov V. K., Sliva A. P., Scherbakov A. V. � Welding rate effect on weld seam formation at electron-beam through penetration welding

The conditions for the free formation of electron-beam welding seams at the lower position with a through-penetration are discussed and also dynamic model of the liquid metal flowing from the root of the molten pool is considered. During this flowing at the initial time metal is moving with an acceleration downward, but as a heat source is moving, the acceleration decreases because of reducing the width of the seam due to the crystallization and increasing the surface tension forces. The calculation method, which allows to determine the minimum speed of welding at which the seams may be formed without top understatement, is proposed.
Key words: electron-beam welding, through penetration, speed of welding, method

Karguin V. A., Tikhomirova L. B., Galay M. S., Kuznetsova Ye. S. � Performance parameters enhancement of joints obtained by aluminothermic welding

Metallographic examination results of railing welded joints, carried out by aluminothermic welding are presented. Measurement data of aluminothermic welds� hardness showed midrange of weld hardness as 240�290 ��. According to technical specifications 0921-127-01124323�2005 the hardness value does not completely meet the requirements of the least hardness indexes.
Key words: aluminothermic welding, rails, hardness, welded joints
