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(jī)還可以將工件進(jìn)行回轉(zhuǎn)和傾斜，方便將較復(fù)雜的結(jié)構(gòu)件直接的置于焊縫的水平，或者是船形的位置等進(jìn)行施焊。因此焊接變位機(jī)整個(gè)驅(qū)動(dòng)的系統(tǒng)可以分為兩方面：1.翻轉(zhuǎn)的驅(qū)動(dòng)；2.回轉(zhuǎn)的驅(qū)動(dòng)。其中翻轉(zhuǎn)的驅(qū)動(dòng)可以分為液壓和電動(dòng)兩種不同的形式；而回轉(zhuǎn)的驅(qū)動(dòng)則比較常見(jiàn)的是電動(dòng)的驅(qū)動(dòng)，速度屬于無(wú)極的調(diào)節(jié)，可以實(shí)現(xiàn)正反兩種轉(zhuǎn)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(jī)，或者是對(duì)于工作臺(tái)要求升降幅度比較小的焊接變位機(jī)，在升降和傾斜的裝置上選用液壓的驅(qū)動(dòng)比較常見(jiàn)。而液壓的驅(qū)動(dòng)大優(yōu)點(diǎn)則是比較便于進(jìn)行控制，結(jié)構(gòu)的特點(diǎn)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.
