主　　题：Finite element (FE) Residual stresses Weldment 2.25Cr IMo steel 

摘      要：In this paper the residual stresses in a butt-welded plate of 2.25Cr 1Mo has been analyzed using a 3D and transient finite element (FE) *** the effect of the welding-electrode speed has been studied using death and birth of *** this purpose,a coupled thermo-mechanical FE solution has been used to obtain the temperature distribution and the resulting residual ***,the variations of the physical properties of the material with temperature have been taken into *** show that the residual stresses in the heat affected zone (HAZ) are maximum and change along the weld and also in the *** has been shown that use of the 3D and transient model will lead to more accurate and realistic results which are well compared with the experimental test data.
