Investigation of residual stresses in dissimilar copper-steel joint welded by electron beam

Year: 2019

Type: article

Abstract: The results of experimental determination of residual stress distribution in dissimilar materials welded by EBW method via neutron diffraction are presented. The joints between copper and stainless steel were investigated. Two samples with different beam current were welded. The residual stresses were measured using TOF diffraction method at a pulsed neutron source. The strain is determined by the relative change in the neutron time of flight. Analysis of the widths of the peaks made it possible to obtain information on microstrains in the samples. The residual stresses in copper do not exceed 100 MPa in both samples. The maximum stresses can be seen in the steel zone of thermal impact in the X component - 450 MPa.
