Impact welding is a type of welding that allows you to weld dissimilar materials. Impact welding creates high temperature in the place of impact of the workpieces due to the released kinetic energy. Kinetic energy is transmitted to the workpieces through the electric discharge of a capacitor or by a mechanical hammer. The heat released during the transfer of kinetic energy into heat contributes to welding.
Impact welding is used to join dissimilar metals. Welding is carried out in materials that have a small cross section. In the workpieces being welded, under the application of a dynamic load, plastic deformation is localized in the contact zone and the surface microroughness is instantly removed.
The advantage of impact welding is a small heating zone and a short welding time of about 16 milliseconds.
