  • In order to explore the multiaxial high-cycle fatigue performances of welded members of steel pipe, the uniaxial tensile and torsional high-cycle fatigue tests of welded members of steel pipe were designed to obtain the stress-life curve (S-N curve) and fatigue parameters of welded members of steel pipe. On this basis, the modified Wöhler curve method(MWCM) based on critical surface theory was adopted to analyze the multiaxial high-cycle fatigue performances of welded members.The results showed that the uniaxial high-cycle fatigue performances of welded members of steel pipe was much lower than that of base metal with the same strength. With the increase of the ratio of normal stress amplitude to shear stress amplitude on fatigue critical plane, the fatigue life curve kept moving downward and the fatigue strength decreased. When the ratio of normal stress amplitude to shear stress amplitude on the critical plane remained constant, the multiaxial fatigue life decreased with the increase of shear stress amplitude on the critical plane. When the shear stress amplitude on the critical plane remained unchanged, the multiaxial fatigue life decreased with the increase of the normal stress amplitude on the critical plane.
