| 摘 要： | 为了解决螺旋焊管预精焊机组精焊内焊臂振动导致的内焊缝质量问题，分析了预精焊机组精焊内焊臂在焊接过程中的振动原因，利用ANSYS 15.0 workbench 有限元分析软件，模拟了内焊臂由于电弧不稳定引起的振动问题。结合模拟数据与实际生产情况，设计了一套精焊内焊臂自动稳定机构，同时配合控制预焊缝的飞溅物、氧化物、烧穿、断弧等缺陷的修磨以及引熄弧板的稳定过渡，减少了焊接过程中的振动问题，提高了精焊内焊缝的焊接质量。

| Abstract: | In order to solve the quality problem of inside weld caused by inside welding arm vibration of SAWH pipe tack-finish welding unit, it analyzed the vibration reason. It simulated the welding vibration caused by electric arc instability utilizing the finite element analysis software ANSYS workbench 15.0, designed a set of automatic stabilization mechanism for finish welding inside welding arm combined with the simulated data and actual production conditions, at the same time cooperated with control tack welding spatter, oxide, burn through, defects grinding such as arc breaking, and the stable transition of up arc tab/down arc tab, which can reduce the vibration problem in welding process, improve the welding quality of finish welding inside weld. |
