In addition, due to the effect of heat input, the workpiece may be deformed. At this time, in order to maintain the correct position of the welded joint, the position of the workpiece needs to be fine-tuned to compensate for the impact of the deformation. However, the equipment does not cope with such situations. For this reason, we propose a three-axis dual-station flip welding positioner. Utility Model Content
