SOME PHYSICAL PROCESSES IN THE APPLICATION OF THE ELECTRODYNAMIC METHOD OF METAL PROCESSING

Abstract

On the basis of the developed analytical mathematical model of non-stationary process of local electrodynamic treatment of metal structures, especially welded joints, and estimation of the main dynamic, electrophysical and thermal characteristics of the process are considered. The characteristics of the motion of the electrode, the distribution of the pulse current in the metal plate, the heating of the metal are found and analyzed. The conclusion about the possibility of realization of devices with simultaneous supply of current pulses of necessary parameters on the shock electromagnetic element and through an electrode to the metal plate to achieve the effect of electroplasticity is made.
