Principle of selection of welding positioner

- May 28, 2019-

The selection principle of welding positioner has the following three points: one is the principle of application of the workpiece, the other is the principle of convenient welding, and the third is the principle of easy operation.


(1) Principles of workpiece application


The structural shapes of different structural parts of construction 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 the welded structural parts.


(2) Convenient welding principle


According to the condition of manual welding, 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) Easy to operate principle


Should choose safe and reliable, open, low operating height, compact welding positioner, in order to facilitate the operation of the workers and the 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.


The L-shaped double-slewing welding positioner can be selected for the rear axle box of the welding bulldozer. The welding excavator X frame can be used with the double-seat head-to-tail double-slewing welding positioner. The welding bulldozer frame can be used with the roller frame welding positioner. The welding excavator bucket can be equipped with a C-shaped double-rotation welding positioner, and the welding excavator boom and roller frame can be double-column single-rotation positioner.
