When welding large‑size workpieces, operational efficiency is often affected not only by welding procedures, but also by whether workpieces can be quickly adjusted to proper positions. For bulky, heavy workpieces with complex weld distribution, frequent flipping and re‑positioning using lifting equipment adds extensive auxiliary operations and tends to interrupt continuous welding. The L‑type positioner adjusts workpiece posture via tilting and rotation, bringing welds at various positions into accessible welding zones. Orientation changes can be completed directly by the equipment, eliminating repeated hoisting and manual handling for smoother welding workflows. Beyond supporting and tilting workpieces, the L‑shaped frame delivers flexible operating space for welding. As the worktable tilts, the workpiece can align with welding stations from multiple directions. Welds originally located on sides, rear surfaces or hard‑to‑reach spots obtain favourable working angles. For multi‑sided weldments requiring frequent orientation changes or complex structures, posture adjustment reduces re‑clamping times and cuts down auxiliary work for welders adapting to workpiece positions. When combined with automatic welding equipment, optimised workpiece posture enables welding tools to easily access target zones and facilitates uninterrupted welding. Workpieces vary greatly in dimension, weight and centre‑of‑gravity position; therefore a single standard positioner cannot satisfy all application scenarios. Xushen provides customised...

During the manufacturing of large cylinders, pressure vessels and heavy steel structures, workpieces feature large diameters and heavy dead weights. Conventional hoisting and manual turnover methods involve cumbersome operations, which greatly restrict welding efficiency. To meet the requirements for continuous circumferential seam welding of large cylindrical workpieces, Xushen Intelligent provides customers with complete sets of welding rotator solutions. This project is equipped with heavy-duty welding rotators. The driving rollers drive the workpiece to rotate smoothly and offer reliable support for the workpiece. Adopting high-strength mechanical structure and stable drive system, the equipment adapts to long-duration continuous rotation working conditions of heavy workpieces. Driven by the rotator for steady rotation, welders or automatic welding systems can finish cylinder circumferential seam welding at fixed stations, drastically cutting repeated workpiece hoisting and re-alignment procedures. During on-site production, constant-speed workpiece rotation improves welding continuity and reduces auxiliary man-hours, creating favorable conditions for matching with automatic welding equipment. This type of rotator supports customized configuration according to workpiece weight, diameter and production process. It can be combined with welding manipulators, submerged arc welding systems and other equipment to form a complete automatic cylinder welding workstation. With reliable load-bearing capacity and smooth driving performance, Xushen Intelligent...

In the field of heavy equipment manufacturing, workpieces are becoming larger and heavier, making stable positioning and efficient welding increasingly important challenges. For large cylinders, pressure vessels, and heavy structural components, traditional manual adjustment or crane-assisted turning methods are often complicated and may affect welding consistency, production efficiency, and operational safety. A welding positioner is an important auxiliary device developed to meet the welding requirements of large workpieces. Through rotation and tilting functions, the welding positioner allows the workpiece to be adjusted to an ideal welding position, improving accessibility to weld seams and reducing difficult welding operations. It also minimizes repeated lifting and manual turning, helping improve welding stability and overall production efficiency. With the development of automated manufacturing, welding positioners have become an essential part of modern welding systems. Zhengzhou Xushen Intelligent Equipment Co., Ltd. provides welding positioners with different load capacities according to customers’ workpiece sizes, weights, and welding requirements. Heavy-duty welding positioners are widely used for large structures, pressure vessels, storage tanks, and other industrial applications, and can work together with welding manipulators and automatic welding systems to provide efficient and reliable welding automation solutions.

The Xushen 6×4 Welding Manipulator is designed to improve the efficiency and precision of automated welding for large workpieces. Featuring a column-and-boom structure with a 6 m vertical travel and 4 m horizontal boom travel, it provides an extensive working range for longitudinal, circumferential, internal, and external welding applications. Built with a high-strength steel frame, the manipulator offers excellent rigidity and operational stability. Both the boom lifting and extension systems are equipped with variable frequency drive (VFD) control for smooth movement and accurate positioning. The system can be integrated with welding rotators, welding positioners, and SAW, MIG/MAG, or TIG welding power sources to create a complete automated welding solution. Designed for maximum flexibility, the welding manipulator is available in both stationary and rail-traveling configurations. Optional features include a flux recovery system, Automatic Arc Voltage Control (AVC), laser seam tracking, industrial camera monitoring, PLC automatic control, and wireless remote control, allowing the system to be tailored to different production requirements. An anti-fall safety mechanism and comprehensive electrical protection system ensure safe, reliable, and continuous operation while reducing labor intensity and improving weld quality. The Xushen Welding Manipulator is widely used in the fabrication of pressure vessels, storage tanks, pipelines, petrochemical equipment,...
