Abstract
Treatment with a pulsed electromagnetic field (TPEMF) of welded joints leads to a decrease in the level of residual welding stresses. TPEMF in the welding process contributes to an increase in the efficiency of the welding process (compared to TPEMF after welding) and the simplicity of its technical implementation. On the basis of mathematical modeling and experimental studies of magnetic pulse processes, an automated complex for TIG welding has been developed that is compatible with the TPEMF of the weld metal under the conditions of a thermal deformation welding cycle.
Keywords: pulsed electromagnetic field, welded joints, residual welding stresses, TIG welding, structure dispersion, mathematical modeling, aluminium alloy
