Abstract
Current concepts of the influence of structural material treatment by current pulses on their mechanical properties are generalized. Types of electric pulse impact on current-carrying materials are classified, and prospects for its application to improve the mechanical properties of welded joints are outlined. It is established that electric pulse treatment of welded joints may be promising for extending the service life of metal structures.
Keywords: welded structures, electric pulse treatment, electric stimulation, electromagnetic field action, structural materials, aluminium alloys, specific treatment energy, current density, corrosion resistance, residual stresses
