Abstract
One of the factors that increase penetrating power of the pulsed arc is making the current pulse frequency match the frequency of natural free oscillations of the weld pool. Device that allows fixation of amplitude and period of oscillations of the metal melt during welding has been made to find conditions for "resonance" to be established between the disturbing force and natural oscillations of the weld pool.
