In the present study, the effect of tension overloading on the fatigue life of 16Mn steel butt welds and the macro-residual stress in the surface layer near the weld toe was experimentally investigated. Test results and analysis showed that tension overloading has no appreciable effect on the fatigue life of 16Mn steel butt welds although the residual compression stress in the surface layer near weld toe is thus increased. This may suggest that the main factor affecting the said fatigue life and overloading effect is not the macro-residual stress in the surface layer. besides, the engineering applications of the test results were also briefly discussed.

本文实验研究拉伸超载对16Mn钢对接接头的疲劳寿命及焊趾处表面残余应力的影响。实验结果与分析表明,拉伸超载虽能提高焊趾处表面宏观残余压应力的绝对值,但对16Mn钢对接接头的疲劳寿命无明显的影响。这说明影响16Mn钢对接接头疲劳寿命及其超载效应的主要因素,不是超载引起的焊趾处表面的宏观残余应力。此外,还对试验结果的工程应用作了简要的讨论。
