Using rigid modes effects on the bonding region in most cases causes the formation of a contact during the crystallization in the liquid phase, which is highly undesirable when connecting non-ferrous metals and their alloys. Forming permanent joints in the liquid phase facilitate processes atomic hetero diffusion or reactive diffusion, which intensifies the nucleation of intermetallic phases. The use of high-voltage capacitor welding with an induction-dynamic drive allows minimizing the processes of nucleation of intermetallic phases due to the use of super-hard modes of action on the connection zone when converting the stored energy in capacitor banks to synchronous thermodynamic effects. The proposed methods of high-voltage capacitor welding for joining dissimilar alloys and powder compositions are considered, the physical nature of the process and the kinetics of the impact are described.
