Abstract
The article analyses Monel-400 alloy cylinder circle weld temperature field and residual stress field by finite element,using ANSYS finite element analyse of large-scale general-purpse software, and draw the thermal cycling curves of the weld fusion line and near location.Then the temperature of node in thermal analysis as the result load on the body of the numerical simulation calculation of stress results show that:The stress of the surfae direction node of x beginning to tensile stress,then transform for the compressive stress, but the nodes of the internediate and the inside surface in x direction is always compressive stress,And the stress value more than appearance;The stress in the node of the surface is the largest in the y direction is 175 MPa,it is 76％ on the yield strength,the highest tensile stress of intermediate nodes and the inside surface nodes .The distribution of the stress in z direction and x direction are the same.关键词
