摘要

为探讨焊趾工艺优化方案对压力管道对接接头残余应力分布的影响，以提高管道的疲劳寿命和整体性能。通过设计三种不同的焊趾工艺优化方案，利用有限元分析模拟了三种方案对X70管线钢对接接头周向和轴向残余应力的影响，并采用盲孔法对仿真结果进行了验证。仿真和试验结果表明，三种优化方案的周向和轴向残余应力变化趋势基本一致；焊趾位置凹形过渡（方案2）在减少应力峰值和平均应力方面表现最佳，其周向残余应力峰值为539.22 MPa，轴向应力峰值为204.57 MPa；盲孔法测量结果显示，残余应力仿真与试验结果趋势一致，误差控制在8.5%以内，该结果验证了仿真模型的可靠性。焊趾位置的凹形过渡设计能有效降低残余应力，提高压力管道的安全性和耐用性。

Abstract

To explore the impact of welding toe process optimization schemes on the distribution of residual stress in pressure pipeline butt joint

with the aim of enhancing the pipeline's fatigue life and overall performance. Three different welding toe process optimization schemes were designed

and the effects of these schemes on circumferential and axial residual stress were simulated using finite element analysis

with blind hole testing employed to validate the simulation results. The simulation and experimental results indicate that the circumferential and axial residual stress trends of the three optimization schemes are essentially consistent; the concave transition at the welding toe (Scheme 2) performed best in reducing stress peak and average stress

with a peak circumferential residual stress of 539.22 MPa and a peak axial stress of 204.57 MPa; blind hole testing results show that the residual stress simulation is consistent with the experimental results

with an error controlled within 8.5%

verifying the reliability of the simulation model; the concave transition design at the welding toe can effectively reduce residual stress and improve the safety and durability of pressure pipelines.
