摘要:
以X80钢级Φ1 219 mm直缝埋弧焊管为研究对象,采用有限元软件ABAQUS,通过顺序耦合算法和移动热源子程序及生死单元形式,对钢管直缝焊和经热处理后焊缝的残余应力进行了数值模拟,分析焊后热处理对焊缝残余应力的改善作用。结果表明,焊缝等效最大残余应力和轴向拉应力均出现在外层焊缝的中心处,局部焊后热处理能降低焊缝的残余应力,等效峰值应力由560 MPa左右降低到约430 MPa,降低了23.2%;焊缝轴向拉应力也由450 MPa降低到370 MPa。焊后热处理对残余应力分布影响不大,但能使焊接接头的应力变得更为均匀。
Abstract:
Taking X80 steel Φ1 219mm SAWL pipe weld the research object, the residual stress of straight weld and weld after heat treatment was simulated by finite element software ABAQUS through sequential coupling algorithm, moving heat source subroutine and birth?eath element form, and the improvement effect of post?eld heat treatment on weld residual stress was analyzed. The results show that the equivalent maximum residual stress and axial tensile stress of the weld of SAWL pipe both appear in the center of the outer weld, and the local post?elding heat treatment can reduce the residual stress of the weld, and the equivalent peak stress decreases from 560 MPa to 430 MPa, which reduces by 23.2%. The axial tensile stress of the weld is also reduced from 450 MPa to 370 MPa. Post?elding heat treatment has little effect on residual stress distribution, but can make the stress of weld more uniform.
