Abstract
Influence of design features of fastening the samples of AMg6 alloy and its welded joints in the grips of testing machine on decrease in deformation resistance at electrodynamic treatment is shown. It is established that the effectiveness of electrodynamic effect is decreased with increase in thickness of metal being treated.
