Abstract: o satisfy the needs of probabilistic fatigue analysis,on certain assumption conditions,the relationships between Detail Fatigue Rating(DFR)and other fatigue parameters under con- stant stress ratios are obtained. Analysis of the fatigue test results of welding specimens shows that the relationships are correct.

Key words: probability-fatigue, fatigue tests, weld strengths
