【Abstract】 In this article, with the finite element method(FEM), the magnitude and distribution of residual stress in butt welds are estimated, the calculated results are compared with the test results, showing good agreement, which can prove the FEM to be the economical and effective method to predict the welding residual stress, and it can provide the theoretical direction to draw up the correct welding technology and improve the properties of welding joint.更多还原
