| Abstract: | The welding residual stress in high-pressure hydrogenation heat exchanger has been studied.The general problem of seal joint was the leakage of welding structure by crack.Welding residual stress was one of the main affect factors.Using the finite element analysis software ABAQUS,a sequentially coupled fillet welding thermal-stress program was developed to discuss the influence of fillet angle and fillet size on welding residual stress.The stress distribution of a fillet weld sealing joint in the high pressu... |
