Abstract
The effect of exposure to non-uniform magnetic field on residual welding stresses in specimens of aluminium alloy D16 has been studied. It is shown that a long exposure of specimens containing a weld leads to a substantial decrease in the value of residual stresses. Suggested is an explanation to the observed effect
Keywords: metal structures, welded joints, residual stresses, non-uniform magnetic field, acoustic testing
