both sides welding

A thin Cu coating was deposited on both sides of AZ31 magnesium alloy to be joined to study the material flow in friction stir welding.

在AZ31镁合金待焊表面镀一层很薄的铜层来研究塑性材料的流动情况。

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

螺旋管双面埋弧焊焊接热循环的测定

The procedure parameters to keep smooth bead on both sides with single side welding for the sheet, groove size of backing, assembly gap, traverse tolerance between wire and workpiece are all determined by experiment.

通过工艺试验，确定了保证薄板单面焊双面成形、光滑均匀的工艺参数范围、背面垫板凹槽尺寸、工件装配间隙、焊丝和工件的横向偏差量等。
