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.
