Paton Electric Welding Institute of the National Academy of Sciences of Ukraine popup.description2 Created technology, methods and equipment for non-destructive determination of residual stresses in on the basis of the current pulse for local relaxation of residual stresses and displacements registration method of electronic speckle interferometry. A study to determine the influence of electrical parameters established electrode system to the relaxation of stress state in samples of alloy AMh5 when injected current pulses of high density. Comparison of results of determination of residual stresses by hole and the developed method in welded joints of material AMh5. The discrepancy between the results of the determination of residual stresses specified methods in welded joints does not exceed 20 MPa. On the basis of developed experimental techniques evaluated parameters of pulsed current, dynamic pressure on the magnetic field in electrodynamic treatment (EDO). The effect size of the charging voltage and capacitors on the relative efficiency of Edo. Established that the maximum pulse current and the growth rate is directly dependent on the applied charging voltage, and the rate of growth of the dynamic pressure is a function of step size pulse current. The analysis of the characteristic lesions of intermediate body aircraft engine with magnesium alloy ML9 that can be processed by EDO. Calculated permissible norms of the operators in a magnetic field initiated by EDO.
