Self-aligning Welding Rotator


Our self-aligning welding rotator is developed by incorporating the advantages of similar products both domestically and internationally, while considering the usage requirements of several boiler and pressure vessel manufacturing plants. It is widely used for welding metal cylinders and is a specialized equipment required for the manufacturing of boilers, pressure vessels, and more. The self-aligning welding rotator features advanced technology, reliable quality, and easy operation.

Performance features

  • The standard self-aligning welding rotator consists of an active frame and a passive frame, and can also be customized with one active frame and multiple passive frames, providing ease of use and strong adaptability.

  • The roller group's inclination angle can be automatically adjusted according to the diameter of the workpiece, eliminating the need for manual adjustment.

  • All four wheels of the active frame adopt gear meshing transmission, enabling four-wheel drive.

  • The polyurethane-coated wheels have high friction, long lifespan, and strong load-bearing capacity.

  • The adoption of AC frequency converter allows for stepless speed control, providing high starting torque, a wide speed range, stable operation, and multiple protection functions such as overvoltage, overcurrent, overload, and overheating.

  • The start, stop, forward, reverse, and speed adjustment of the active roller frame are operated on the remote control box.

  • There is an interface for linkage control, enabling integration with operating machines for welding center formation.
