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.

而且焊接变位机还可以将工件进行回转和倾斜，方便将较复杂的结构件直接的置于焊缝的水平，或者是船形的位置等进行施焊。因此焊接变位机整个驱动的系统可以分为两方面：1.翻转的驱动；2.回转的驱动。其中翻转的驱动可以分为液压和电动两种不同的形式；而回转的驱动则比较常见的是电动的驱动，速度属于无极的调节，可以实现正反两种转向。

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.

如果是大型的焊接变位机，或者是对于工作台要求升降幅度比较小的焊接变位机，在升降和倾斜的装置上选用液压的驱动比较常见。而液压的驱动大优点则是比较便于进行控制，结构的特点可以分为，在调速的精度上比较高，可靠的性能非常好，且焊接非常的稳定等。

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.
