摘要:
为了研究HFW焊管滚槽加工中焊缝区域开裂的原因,基于热-力顺序耦合、显示动力学的理论,利用ABAQUS有限元模拟分析软件,建立焊接与滚槽工艺模型,分析了加工工艺对滚槽开裂的影响,并通过试验验证了模型的准确性。研究表明:进行滚压加工中,焊缝处的焊接残余应力会影响滚压最大压力以及最大切向应力值;在总下压量一定时,滚压圈数大于6圈,焊缝处所受滚压压力以及最大切向应力趋于稳定且小于材料抗拉强度;均匀下压时,焊缝处所受滚压压力和最大切向应力最小;滚压初位置在母材区域时,焊缝处所受滚压压力和最大切向应力最小。
Abstract:
In order to study the reason of weld seam cracking in HFW welded pipe rolling groove processing, based on the theory of thermal mechanical sequence coupling and display dynamics, using ABAQUS finite element simulation analysis software, a welding and rolling groove process model was established, and the influence of processing technology on the rolling groove cracking was analyzed, and the accuracy of the model was verified through experiments. The results show that the welding residual stress at the weld seam will affect the maximum rolling pressure and the maximum tangential stress during the rolling process. When the total downforce is constant, the number of rolling coils is more than 6, and the rolling pressure and the maximum tangential stress on the weld tend to be stable and less than the tensile strength of the material. When the pressure is uniform, the rolling pressure and the maximum tangential stress at the weld seam are minimum. When the initial rolling position is in the base metal area, the rolling pressure and the maximum tangential stress at the weld seam are the minimum.
