E.O. Paton Electric Welding Institute of the NAS of Ukraine 11 Kazymyr Malevych Str., 03150, Kyiv, Ukraine. E-mail: olha.mikhodui@gmail.comThe technology of electrodynamic treatment (EDT) of prototypes of thin-sheet butt welded joints of Al, Ni, Ti alloys and austenitic steel was developed and implemented. Specialized assembly tooling was designed, which was used to perform automatic TIG welding of the prototypes. The effect of EDT on residual stresses in welded joint samples was studied using the electron speckle interferometry method. It was found that EDT is an effective mechanism for controlling the residual stressed states of welded joints of Al and Ti alloys and austenitic steel. It is shown that to improve the efficiency of EDT of a Ni-based alloy, it is necessary to use higher values of electrodynamic action energy in the framework of further research. It is also advisable to use a new processing method based on magnetic pulse effects on nonferromagnetic materials to optimize the residual stressed states of welded joints of Ni-based alloys. 19 Ref., 8 Tabl., 11 Fig.
