Abstract
The mechanism of reduction of preliminary stresses in repeated loading and electrodynamic treatment of AMg6 alloy and its welded joints were investigated on the basis of the developed procedure. It was established that the history of loading of AMg6 alloy has no substantial effect on relaxation characteristics of metal subjected to repeated impact by current pulses.
