摘      要：For researching the residual stress distribution characteristics of the different large thickness titanium alloy joints by electron beam welding,under heat treatment or non-heat treatment conditions,the changes in residual stress distribution characteristics of electron beam welding joints,which thickness is 50 mm,were measured using blind-hole method with local layer-by-layer *** of post-welding heat treatment on the residual stress distribution also *** results show that blind-hole method with local layer-by-layer removal is suitable to measure residual stresses in thick plate,and good to reflect the welded residual stress distribution of large *** stress of the test samples in the weld and heat affected zone has high stress level,and internal stress dramatic changes with thickness in this *** heat treatment,the samples stress distributions were significantly *** samples transverse and longitudinal residual stress are basically the *** is obvious.
