In fact, the service life and productivity of the welding positioner depend not only on the weight and correct positioning of the workpiece, but also on the loaded current of the positioner. The positioner can directly rotate and tilt the workpiece to ensure that the whole weld can always be in a horizontal welding position, Moreover, the positioner itself is a high-energy and universal welding equipment that can realize circumferential seam welding. It can be combined with argon arc welding wire feeder, plasma welding machine, melting electrode gas protection welding machine and welding machine power supply to form an automatic welding system.

而且焊接變位機還可以將工件進行回轉和傾斜，方便將較復雜的結構件直接的置于焊縫的水平，或者是船形的位置等進行施焊。因此焊接變位機整個驅(qū)動的系統(tǒng)可以分為兩方面：1.翻轉的驅(qū)動；2.回轉的驅(qū)動。其中翻轉的驅(qū)動可以分為液壓和電動兩種不同的形式；而回轉的驅(qū)動則比較常見的是電動的驅(qū)動，速度屬于無極的調(diào)節(jié)，可以實現(xiàn)正反兩種轉向。

Moreover, the welding positioner can also rotate and tilt the workpiece, which is convenient to directly place the more complex structural parts at the level of the weld, or ship shaped position for welding. Therefore, the whole driving system of welding positioner can be divided into two aspects: 1. Overturning driving; 2. Swing drive. The overturning drive can be divided into two different forms: hydraulic and electric; The rotary drive is more common electric drive. The speed belongs to stepless adjustment, which can realize positive and negative steering.

如果是大型的焊接變位機，或者是對于工作臺要求升降幅度比較小的焊接變位機，在升降和傾斜的裝置上選用液壓的驅(qū)動比較常見。而液壓的驅(qū)動大優(yōu)點則是比較便于進行控制，結構的特點可以分為，在調(diào)速的精度上比較高，可靠的性能非常好，且焊接非常的穩(wěn)定等。

If it is a large welding positioner or a welding positioner that requires a relatively small lifting range for the workbench, it is common to select hydraulic drive on the lifting and tilting device. The great advantage of hydraulic drive is that it is relatively easy to control. The structural characteristics can be divided into high speed regulation accuracy, very good reliable performance, and very stable welding.
