The pedestal welding positioner can turn the work to the ideal welding position for welding. There is also a rotational degree of freedom on the table of the pedestal welding positioner. Variable frequency stepless speed regulation is adopted for table rotation, and the table is driven to tilt by sector gear or hydraulic cylinder. Turning and turning are driven by two shafts respectively. The worktable holding the workpiece can not only turn around its own axis, but also tilt or turn around another axis. It can adjust the welds at various positions on the weldment to the horizontal or "ship type" welding position, which is suitable for welding of frame type, box type, disk type and other non long type workpieces.

The double seat welding positioner not only has good overall stability, but also can realize joint control with the operator or welding machine. There are three options for the control system: button digital control, switch digital control and switch relay control. Generally, it does not need to be fixed on the ground, so it is convenient to move. Its application range is 1 to 50t workpiece's turnover and displacement, which is the structure form with the largest output, the most complete specification and the most widely used at present. It is often used in cooperation with telescopic welding manipulator or arc welding robot.

Most of them are used together with large-scale gantry welding operators or telescopic arm welding operators. The double seat welding positioner is suitable for the overturning and positioning of large size weldments over 50t. In welding operation, it is often used with large-scale gantry welding operator or telescopic arm welding operator. The pedestal welding positioner is applied to the welding of various shaft, disk, cylinder and other rotating parts. It is the most widely used structural form at present.
