振动法消除蒸压釜焊接残余应力的研究及应用

RESIDUAL STRESS REDUCING FOR PRESSURE STILL WELDS BY USING VIBRATION TREATMENT

通过焊接试板、蒸压釜部件及整体蒸压釜的振动处理试验,证明振动处理可以降低结构的焊接残余应力,为低压容器消除焊接残余应力处理闯出了一条新路。

Through vibration treated experiment for weld specimens, still component and pressure still itself, it is proved that residual stress in welded structure can be reduced definitely. This indicates a new way to eliminate residual stress in the welds of low pressure vesseles.
