What Are The Five Principles Of Welding Positioner Selection?

- Jul 28, 2019-

The weight of the welding positioner and the center of gravity and eccentricity of the weldment on the entire work surface should be guaranteed within the corresponding data range, and also ensure a certain capacity. In addition to these, it is necessary to consider whether it is easy to operate, whether the welding is convenient or the like. So what are the requirements for the welding positioner when it is selected?


The welding positioner selection principle has the following five points:


1. Applicable principle of workpieces The structural shapes of different structural parts of engineering machinery vary greatly, and the requirements for displacement during welding are also different. Therefore, the applicable welding positioner should be selected according to the structural characteristics and welding requirements of welded structural parts.


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


3. If the optional welding positioner is for circumferential seam welding, the speed of the 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. The smooth requirements in operation can meet the processing of the entire process.


4. 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 inclination of the table, or whether the angle of inclination can satisfy the welding position of the weldment, etc. When the contact between the corner and the weldment occurs, the gap between the corners and the weldment is required to be larger, so as to ensure the processing requirements of the entire weld.


5, easy to operate principle should choose safe and reliable, open, low operating height, compact welding positioner, in order to facilitate the operation of workers and welding positioner. If the welding structure of the welded structural positioner has a high welding height, the worker can weld by means of a heightening method, or can be adjusted by a hydraulic lifting platform.
