Abstract
The fatigue crack propagation rates of butt welded joints have been actually measured with using natural gas pipeline and bridge as the typical structures.The fracture life have been estimated according to the standards both domestic and abroad,and a curve of stress amplitude vs.life was obtained.A complete method for estimation of service life of welded structure is given in this paper.
