Abstract
Influence of various variants of discharge circuits on effectiveness of electrodynamic treatment (EDT) of aluminium alloy AMg6 and its welded joints was studied. It is established that maximum EDT effectiveness is achieved at simultaneous impact of pulsed electric current and dynamic load on the treated metal, while minimum effectiveness is achieved at the impact of just the pulsed current. Deformation wave parameters were studied at EDT of AMg6 alloy welded joints.
