In this paper the HAZ weld thermal cycles of the welding by both sides submerged arc welded steel pipe were reproduced by the dislocation overlap weld method .

采用焊道错位叠加方法，再现了螺旋管 双面埋弧焊制管过程中内、外 焊焊接热影响区（HAZ）的 焊接热循环。

The Measurement of Weld Thermal Cycle in Welding by Both Sides SAW Spiral Pipe

Study of Welding by One Side and Both Sides Formation with Fine Wire CO_2 Arc Welding

细丝CO2单面 焊 双面成形 的研究

For the thicker steel plates welding can be accomplished by submerged arc-welding with both sides but when one side of the plate was welded the other face must be turned over in order to be welded .

埋弧焊对于比较厚的钢板可以 两面 各 焊一次来完成，但是焊完一面后，必须将工件翻过来再焊另一面。
