In the welding of large cylinders, pressure vessels, storage tanks and heavy steel structures, difficulties in weld positioning, low efficiency of workpiece flipping, and insufficient stability during long-term continuous welding have always been key factors restricting production efficiency. The combined use of welding manipulator and welding positioner realizes synchronous linkage between welding torch and workpiece through dual-machine synergy, providing a more efficient and stable solution for automatic welding of large workpieces. The welding manipulator is responsible for the precise movement and positioning of the welding torch, realizing the lifting, expansion and welding trajectory control of the cross arm, enabling the welding torch to quickly reach different welding positions. The welding positioner performs workpiece rotation and flipping, keeping the weld seam always at the ideal welding angle. After the two machines operate in linkage, frequent manual adjustment of the welding torch and repeated hoisting and flipping of workpieces are unnecessary. The welding process becomes smoother, greatly improving welding efficiency and weld forming quality. Compared with traditional manual welding methods, the combined system of manipulator and positioner is more suitable for automatic welding of large rotary workpieces. The equipment can run stably for a long time, effectively reducing labor intensity, welding deformation...

This adjustable welding rotator is designed to support the rotation of cylindrical workpieces such as tanks, pipes, and pressure vessels during fabrication. By maintaining smooth and stable rotation, it helps keep the weld seam in an optimal position, supporting consistent and controlled welding operations. The system is suitable for fabrication workshops handling medium to large cylindrical components across industries such as oil & gas, steel structures, and process equipment manufacturing. The rotator adopts a manual lead screw adjustment mechanism, allowing flexible adjustment of roller spacing to accommodate different workpiece diameters. Its motor-driven system ensures steady rotation during welding, while the rollers are manufactured with wear-resistant materials to provide reliable load-bearing support. The compact and robust structural design enables stable operation and easy integration into existing workshop layouts. By reducing manual repositioning and improving alignment consistency, this welding rotator supports more efficient fabrication workflows. It provides a practical and adaptable solution for handling cylindrical components of varying sizes, helping manufacturers maintain stable production processes while meeting different project requirements.

In the Zhuhai project, the cantilever welding platform and hydraulic welding rotators are mainly used for welding large cylindrical and pressure vessel workpieces, with a system configuration focused on improving welding stability and continuity. The hydraulic welding rotators serve as the supporting and driving unit during operation. By ensuring smooth rotation of the workpiece, the weld seam remains in an optimal welding position throughout the process. This effectively reduces welding fluctuations caused by changes in workpiece position and minimizes the need for frequent manual adjustments. The hydraulic adjustment structure provides strong adaptability, allowing the system to handle workpieces of different diameters and weights, making it suitable for multi-specification production. The cantilever welding platform focuses on improving operational coverage and flexibility. Through horizontal extension and vertical adjustment, the welding head can move steadily and be positioned accurately over a larger working range. It is especially suitable for long seam and continuous welding operations, helping improve overall process control. The coordinated operation of these two types of equipment makes the welding process smoother, ensures more stable weld formation, and reduces uncertainties caused by manual intervention. It is particularly effective for both longitudinal and circumferential welding of cylindrical workpieces, contributing to improved consistency...
