The weight of the weldment and the center of gravity and the eccentricity of the entire work surface should be within the corresponding date range of the welding positioner. In addition to these, it is also necessary to consider whether it is easy to operate and whether welding is convenient. So what are the requirements and principles when selecting a welding positioner?

The selection principle of welding positioner has the following 5 points:

1. Applying principles of the workpiece

The shape of different structural parts of construction machinery is very different, and the requirements for displacement during welding are also different. Therefore, the suitable welding positioner should be selected according to the structural characteristics and welding requirements of the welded structural parts.

2. Convenient welding principle

According to the situation of the manual welding operation, the selected welding positioner should be able to transfer any welding seam of the welded workpiece to the position of flat welding or ship welding, to avoid vertical welding and overhead welding, and ensure the welding quality.

3. The principle of speed stability

If the optional welding positioner is used for girth welding, the speed of rotation should be considered according to the groove of the weldment. The speed should be within the range of the speed adjustment of the positioner, and the working platform is running. The stability requirements above can meet the processing of the entire process.

4. Tilt angle principle

If the size of the entire weldment of the welding positioner on the outer contour is relatively large, then it is necessary to consider the tilt of the worktable, or whether the tilt angle can meet the optimal welding position of the weldment, etc. When the contact between the corner and the weldment occurs, then when selecting the table, the gap from the ground needs to be greater, so as to ensure the processing requirements of the entire welding.

5. Easy operation principle

Welding positioners with safety and reliability, good openness, low operating height, and compact structure should be selected. It is convenient for workers to operate and place the welding positioner. If the welding operation height of the welding structure positioner is relatively high, the worker can perform welding by padding, or adjust the height position by installing a hydraulic lifting table. The weight of the weldment and the center of gravity and the eccentricity of the entire work surface should be within the corresponding date range of the welding positioner.
