Results of investigations concerning the changes in thin structure of welding joint metal under elec- trohydropulse influence conducted by the method of interal friction are presented. Under this influence the thin structure of the stressed metal is shown to undergo changes in relatively big volume adjacent to the place of discharge. At that, the stabilization of the dislocation structure is accompanied by the decrease in dimensions of dislocation segments that testifies the creation of internal borders in grains.
