摘要:
为保证小直径管道的焊接质量,采用添加铜衬垫的单面焊双面成形方法对小直径管道进行焊接。通过ANSYS软件对小直径管道的合理焊接电流数值进行研究,并对焊接后的小直径管道焊接接头进行表征测试与试验分析,根据仿真试验结果确定小直径管道最佳焊接电流数值。研究表明,最佳的小直径管道焊接电流为100 A,在此焊接电流参数下得到的焊缝正面呈鱼鳞状且背面成形饱满,其金相组织为细小且相互平行的柱状晶,焊缝处显微硬度为205.7HV10,抗拉强度为585 MPa,伸长率为13.7%,获得的焊缝性能较为理想。
Abstract:
In order to ensure the welding quality of small diameter pipe,the single side welding and double side forming method with copper liner is adopted. The reasonable welding current value of small diameter pipeline is studied by ANSYS software,and the welded joint of small diameter pipeline is characterized, tested and analyzed. The optimal welding current value of small-diameter pipeline is determined according to the simulation test results. The research shows that the best welding current for small diameter pipeline is 100 A.Under this welding current parameter,the front of the weld is fish scale and the back is full-ormed. The metallographic structure is small and parallel columnar crystal morphology. The microhardness of the weld is 205.7HV10,the tensile strength is 585 MPa,and the elongation is 13.7%. The obtained weld performance is relatively ideal.
