1) backside melting
背面熔化
2) back fusion zone radius
背面熔化半径
1.
When top fusion zone radius and plate thickness are constant,the three-dimensional shape model at different back fusion zone radius was obtained by analyzing three-dimensional liquid surface of TIG(tungsten inert-gas) welding full-penetrated molten pool with the arc.
在正面熔化半径RZ和板厚h一定的条件下,基于对有电弧作用的熔透型TIG焊接熔池三维液面行为的分析,获得了不同背面熔化半径RB的熔池三维形状模型,利用有限元分析软件surface evolver进行数值模拟,研究了电弧对熔透型TIG焊接熔池液面的影响。
3) the backside image of molten pool
熔池背面
1.
In order to acquire the information of penetration status,vision sensors have been applied to detect the topside image of molten pool,image of keyhole and the backside image of molten pool in hybrid welding respectively.
为获得反映熔透状态的信息,在此采用视觉传感器对焊接过程中的熔池正面、小孔图像、熔池背面分别进行了检测。
4) root running
背面熔接
5) backside width
背面熔宽
1.
The backside width of weld pool was arrived at the desired value by adjusting welding peak current and wire feeding speed at the same time.
在脉冲TIG焊系统中,应用多输入单输出的无模型自适应控制方法,通过同时调节焊接峰值电流及送丝速度,将熔池的背面熔宽控制到期望值。
6) temperature of back side of weld pool
熔池背面温度
补充资料：背面光
背面光(Back light)系逆光照明。遇到散光光源的场合，变成黑色轮廓像，投射以聚光照明，就变成线条影像。其他在摄影棚内对背景进行照明的光。叫做背景光。
