Abstract:  
Based on previous research of strong pulsed magnetic treatment, the effect of a low frequency alternating magnetic field on welding residual stress was studied. The experimental results show that by low frequency alternating magnetic treatment, the residual stresses in both rigid restrained specimens and welded specimens are reduced. Furthermore low frequency alternating magnetic treatment has the feature of simple equipment and easy operation. © 1998 Elsevier Science S.A.
