Sidelnikov Siberian Federal University 79 Svobodny, Krasnoyarsk, 660041, Russia Received 18.12.2014, received in revised form 09.02.2015, accepted 28.02.2015 Developed technology of obtaining rods and wires from silumins using casting in electromagnetic crystallizer and follow combined rolling-extruding and drawing. <...> Were carried studies of properties of deformed semi-fi nished products and obtained experimental batches of welding wire from alloys AlSi5 and AlSi12. <...> Aluminum and aluminum alloys due to their unique technical and operational characteristics occupy an important place in modern industry. <...> The presence of such properties as high electrical conductivity and corrosion resistance combined with low weight led to the fact that aluminum and its alloys are widely used in engineering, electric power industry, transportation, aviation, and other branches of industry. <...> A special place in the structure of production of semi-fi nished products from aluminum and its alloys occupies wire, which is used to make electricity transmission lines, electric transport ropes, cables, electrodes, welding rod, welding wire, etc. <...> Recently, there was a great need © Siberian Federal University. <...> All rights reserved * Corresponding author E-mail address: sokolov.sfu@gmail.com # 180 # Ruslan E. Sokolov and Sergey B. Sidelnikov. <...> Application of Methods Combined Treatment for Obtaining Welding… for the welding wire from silumins due to the high mechanical and corrosion properties of these alloys. <...> These products are widely used in military, space and aviation industry for welding aircraft constructions and are widely used in welding defects in the foundry industry. <...> The high cost semifi nished products from silumins due to large labor-intensive production limits their widespread use in other industries and makes the problem of the development of new technologies to produce deformed products from them actual. <...> Analysis of published data on the trends of industrial development of pressed production of small cross-sectional and wire from aluminum alloys showed that one of them is the use of the combined processes of metal allow obtaining technical and economic advantages by reducing the number of cycles of manufacturing <...>
