“…In this case, the insert that sizes up the gap (h) is knocked out; a layer of molten metal is squeezed out of the overlapping zone together with adsorbed and oxide films and other contaminants. Hot cleaned surfaces are compressed, pressed against the matrix, and the electric resistance welding is performed [4].…”

Various techniques for producing fixed joints in solid using electromagnetic fields are considered; basic diagrams, physics, features, and technical capabilities of each method are described. It is shown that thin-walled tubular irregular structures can be obtained under the magnetic-pulse moulding welding that joins the combined actions of induced currents passing through the overlap zone and magnetic pressure for apposing the weldable edges and for shaping in accordance with the matrix configuration. Obtaining joints from dissimilar materials and structures of different thicknesses is implemented due to shock pulse capacitor welding with magnetic pulse drive. The series connection of the weldable parts enables to synchronize the current flow and force impact on the weld junction. Depending on the combination of the weldable products, three techniques of shock pulse capacitor welding with magnetic pulse drive are proposed. To intensify the quality improvement of the female connectors obtained, it is proposed to use the magnetic-pulse welding in vacuum instead of the diffusion welding. Preheating of the complete unit in vacuum allows for the pre-activation of the connectable surfaces. A unique feature of the implemented diagram is a remote action on the telescopic joints of dissimilar alloys heated in vacuum to the pre-melting temperatures through a quartz glass.

“…Under the condenser welding, the accumulated energy is expended only on the thermal impact. The applied system that creates a mechanical force to compress the components before or during the welding process does not always provide creating forces to displace oxide films from the joint zone [5,6].…”

When obtaining fixed joints of different thickness from dissimilar materials, there arise difficulties associated with various thermophysical properties, and the likelihood of occurrence of intermetallic phases under chemical interaction. The use of super hard modes of thermodynamic effect during high-voltage condenser welding (HCW) provides localizing heat generation in the contact zone of the weld surfaces, activating the surface layers through converging the surfaces with the displacement of molten metal to the periphery of the contact zone and forming bonding in the solid phase.Recommendations are given for the use of technological methods of high-voltage capacitor welding depending on the combinations of welded alloys. A description of the nature and physical processes occurring at each technological reception is given.It is shown that the energy stored in the capacitor banks is spent on heat and power action. Variation of the mass of the induction - dynamic drive pusher and its inductance enables to adjust the ratio of thermal and mechanical components of the HCW process.The energy dispersion analysis of the experimental compounds obtained from dissimilar alloys confirms the absence of diffusion in high-voltage capacitor welding under super-rigid exposure modes.

Аннотация. Рассмотрены особенности получения сварных соединений из цветных сплавов. Описаны недостатки применяемых конденсаторных способов сварки. Для снижения вероятности возникновения интерметаллидных соединений предлагается использовать высоковольтную конденсаторную сварку с индукционно-динамическим приводом (ВКС с ИДП) на супержестких режимах воздействия. Приведены технологические схемы приемов ВКС с ИДП, описана физическая сущность импульсного процесса. За счет вводимой энергии возможно регулировать прочность сварных соединений при ВКС путем изменения числа витков индуктора и массы толкателя ИДП. Представлены зависимости прочности сварных соединений от различных факторов. Приведены результаты сравнительного анализа затрат тепловой энергии в зависимости от технологического приема и шероховатости свариваемых поверхностей, а также соотношения тепловой и механической энергий для каждого приема ВКС с ИДП. Ключевые слова: цветные сплавы, конденсаторная сварка, супержесткий режим, энергия, термодинамическое воздействие, индукционно-динамический привод. * Статья публикуется по рекомендации программного комитета Международной научно-практической конференции "Материаловедение и металлургические технологии" (RusMetalCon-2019), https://rusmetalcon.susu.ru
