SCIENTIFIC-TECHNICAL SECTION

Varukha Ye. N. � Calculation of melting rate of preheated electrode at carbon-dioxide welding

Empirical formula describing dependence of rate of melting (feeding) of wire on current, preheating temperature, electrode size and extension at carbon-dioxide welding with reverse polarity current as well as dependence of empirical coefficients of the formula on process parameters is found. Physical content of these coefficients is shown.
Key words: welding, consumable electrodes, carbon dioxide, reverse polarity, electrode melting rate

Muravyev V. I., Bakhmatov P. V., Debelyak A. A. � Calculation of residual deformations on thermal fields at butt welding of thin plates

Analysis results of the certain graphical methods for definition of welding (residual) deformations inevitably arising under the thermal influence of highly concentrated sources of heat.
Key words: welding, welding deformations, source of heat, model, thermal welding cycle

Varlamov D. P., Steklov O. I. � Defects of corrosion cracking of circumferential welded joints of trunk gas pipelines in the two climatic regions of Russia

It is shown that extremely large quantity of anomalies of welded joints is the risk for safe operation of trunk gas pipeline system not only as possibility of destruction of welded joints but also as formation of the additional factor of origin and development of defects of stress corrosion cracking in the zone of intersection of longitudinal and girth welds.
Key words: pig-assisted inspection, stress corrosion cracking, anomalous girth welded joints

Kravchenko I. N., Shiyan A. V., Zubrilina Ye. M. � Thermoplastic hardening of metal surfaces of welded and built-up parts
