Welding Rotator Series

*Can be customized according to user requirements

Welding rotator is a commonly used welding auxiliary device, which is widely used in the welding production process. It mainly uses the friction between the weldment and the driving roller to drive the rotation of the cylindrical weldment. It can be combined with a welding manipulator, a welding positioner, etc. Realize the automatic welding of inner and outer circular seams, fillet welds and inner and outer longitudinal seams of weldments.


Improved Weld Quality

The controlled and steady rotation ensures even weld bead deposition and consistent weld quality.

Increased Productivity

Welding rotators allow for continuous welding along the length of the workpiece, reducing downtime and improving productivity.

Reduced Labor

The rotation eliminates the need for manual repositioning of the workpiece, reducing the manual labor required for welding around the circumference.


Welding rotators provide a safer and more stable platform for welding, especially for large and heavy cylindrical workpieces.

Composition of Welding Rotator
  • Rollers: Welding rotators consist of a set of powered rollers, usually driven by variable-speed motors. The workpiece sits on the rollers, and the rotation of these rollers allows the workpiece to rotate slowly and steadily during welding.
  • Adjustable Frame: The welding rotator is designed with an adjustable frame to accommodate different sizes of workpieces. The frame can be adjusted to fit various diameters of pipes or cylindrical objects.
  • Motorized Rotation: The rollers are driven by motors, allowing the rotation speed to be controlled according to the welding requirements and workpiece dimensions.
  • Alignment and Centering Mechanism: Welding rotators may have mechanisms to align and center the workpiece on the rollers to ensure that the welding is performed along the axis of the cylinder.
  • Remote Control Panel: Many modern welding rotators come with a remote control panel that allows the operator to adjust the rotation speed and direction, making it easy to operate the equipment safely.


Workpiece Preparation

Before placing the workpiece on the welding rotator, it is prepared by cleaning, beveling (if required), and positioning it correctly on the rollers.

Workpiece Mounting

The workpiece is mounted on the rollers of the welding rotator. Care is taken to ensure that the workpiece is securely placed and balanced to avoid any instability during rotation.

Alignment and Centering

If the welding rotator has an alignment and centering mechanism, the workpiece is aligned and centered to ensure the welding is performed along the axis of the cylinder.

Rotation and Welding

The welding rotator is activated, and the workpiece starts rotating slowly and steadily. The welding process is performed along the length of the workpiece as it rotates, allowing the welder to access the entire circumference without manually repositioning the workpiece.

Continuous Rotation

The rotation continues throughout the welding process until the entire length of the weld joint is completed.

Post-Welding Operations

After welding, post-welding operations such as inspection, cleaning, and other finishing processes may be performed.
