Many types of welding are known in which the energy of ultrasonic oscillations is used in one way or another. One instance is hot-press welding with the application of ultrasound. This technique makes it possible to shorten the welding time and to lower the percentage failure relative to the same type of welding without ultrasound. Experiments have shown that the use of ultrasound in diffusion welding in vacuum or in an inert-gas atmosphere [1, 21 lowers the temperature and shortens the welding time. Some interesting results have been obtained in electric spot welding with the application of ultrasound at the electrode [1, 3]; ultrasound is transmitted at various stages of the welding cycle, whereupon it is possible, in particular, to break down the dendrite structure of the fused core and, accordingly, increase the mechanical qualities of the bond.
