Abstract
Results of evaluation of electromagnetic effects on residual welding stresses of the I and II kind are presented. It is shown that application of low-density current pulses to low-carbon steel welded joints had a specific effect on stresses of the I kind, however, it did not lead to their substantial decrease. It is established that treatment leads to increase of the size of blocks, decrease of stresses of the II kind, and increase of the crystalline lattice parameter of weld metal.
Keywords: steel, welded joints, heat treatment, electromagnetic impact, electrophysical treatment, deformation, residual welding stresses, stresses of the I kind, stresses of the II kind
