Ultrasonic Vibroacoustic Processes, Excited By Heating By Impulse Currents of Metals

KnE Materials Science / 15th International School-Conference "New Materials – Materials of Innovative Energy" (MIE) / Pages 621–628

Abstract

When passing impulse currents through a conductor, powerful vibro-acoustic oscillations are generated in it. The parameters of these oscillations are easy to control. Changing the duty cycle of pulses allows for such equipment as welding with the allocation of a large amount of heat, and regimes of controlled cooling and ultrasonic quality control of the welded joint.


Keywords: welding, vibration, pulse current, diagnostics, ultrasound
