    • Abstract
  • With blind-hole drilling method, the welding residual stress of thick plate was measured under different welded joint types, plate thickness, and welding processes. Considering the plasticity effect, the distribution of welding residual stress in thick plate was obtained. Then, the effects of joint types, plate thickness, welding process, and groove dimensions on the welding stress distributions were discussed. The results show th at: unconstrained structure can reduce the residual stress, and welding sequences adjustment can change the position of residual stress peak values, and proper groove dimensions can effectively reduce the effects of w welding residual stress on the structure strength.
