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,...

During the fabrication of pressure vessels, storage tanks, pipelines, and other large cylindrical workpieces, different workpiece sizes often require different welding center heights. This 20-ton lifting welding rotator features an integral lifting design. Through the coordinated operation of the guiding mechanism and screw lifting system, the platform can be raised and lowered smoothly, providing reliable support for heavy-duty workpieces. Even under high-load conditions, the system maintains excellent stability, minimizing tilting and vibration while meeting the positioning requirements of fit-up and welding operations. The equipment is equipped with four screw lifting mechanisms mounted at the base and driven centrally by a motor and gearbox, ensuring synchronized platform lifting. Operators can conveniently adjust the roller center height to suit the workpiece diameter and welding requirements, enabling quick alignment with welding manipulators and automatic welding systems. For workpieces of varying sizes, height adjustment can be completed without frequent tooling changes, significantly reducing setup time and improving production efficiency. Precise height adjustment also contributes to consistent welding quality and provides ideal conditions for automated welding applications. The rollers are coated with polyurethane, providing sufficient friction while effectively protecting the workpiece surface from scratches and indentations. The excellent wear resistance and shock-absorbing properties of polyurethane...

During wire insertion operations, the accuracy of workpiece positioning directly affects production efficiency and product quality. In traditional processes, adjusting the workpiece position often requires frequent handling or repeated corrections, which not only consume time and labor but can also affect processing accuracy. As production demands continue to increase, manufacturers are placing greater emphasis on positioning efficiency and operational convenience. The dual-station electric rolling wire insertion machine optimizes workpiece support and adjustment, enabling quick positioning of the workpiece at the ideal operating location and providing reliable support for efficient wire insertion. The equipment adopts a dual-station design, enabling alternating operation between two workstations. While wire insertion is being carried out at one station, the other station can be used for workpiece loading and preparation, effectively reducing idle time and improving overall productivity. In addition, the rollers on both sides can rotate and move up and down electrically, allowing flexible adjustment according to workpiece size and process requirements. Operators can complete wire insertion from different angles and positions without frequent handling or repeated repositioning of the workpiece, making the entire process smoother and more efficient. With the advantages of continuous dual-station operation, roller rotation, and height adjustment, the dual-station electric rolling...
