At present a growing interest in pulsed electromagnetic field treatment technologies is observed to improve the mechanical
properties of metals, alloys and welded joints. Based on the pulsed electromagnetic field treatment, effective methods can be
developed to optimize the stress-strain state of aluminum alloy products in order to extend their life for the use in aircraft,
shipbuilding and other industries. The aim of the work is to study the influence of pulsed electromagnetic field treatment on the
stress-strain state of circumferential welded joints of aluminum AMg6 alloy. An original experimental procedure was developed
to study the kinetics of the electrodynamic pressure force during treatment of metallic materials with a pulsed electromagnetic
field. It is shown that as a result of treatment with a pulsed electromagnetic field in the same conditions, the value of P increased
with the use of the screen, which is predetermined by the increase in the active additional volume of the electric conductive
medium. It was established that the use of the screen during treatment by a pulsed electromagnetic field helps to reduce the level
of residual tensile welding stresses and improve the accuracy of circumferential welded joints. 8 Ref., 3 Tabl., 8 Fig.
