Abstract：

The tube sizing process with electromagnetic bulging has been analyzed preliminarily and studied experimentally. The effects of tube materials, discharging voltage and times on the sizing precision of the tube ends are analyzed, with roundness of tube end as evaluating indicator. The studies indicate that materials properties and discharging times have effects on sizing precision, but the discharging voltage is the primary factor for the sizing precision.
