The working principle of this pipe rotator is based on its designed movement and support functions to ensure the stability and controllability of large workpieces during operation. This pipe rotator is equipped with a running gear, usually a combination of wheels and drive. The drive can be electric or hydraulic. Through the control system, the operator can control the movement of the traveling mechanism so that the roller frame can move within the work area.

The welding rotator is a commonly used welding auxiliary device that 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. The combination of welding rotator, welding manipulator and welding positioner can realize automatic welding of internal and external circumferential seams, fillet welds and internal and external longitudinal seams of the tank.

The auto pipe welding machine is a high-performance orbital welding system specially designed for pipe-to-pipe, pipe-to-elbow. The pipe remains fixed while the magnetic welding carriage performs 360° all-position welding automatically, ensuring consistent quality and high efficiency. This auto pipe welding machine supports MIG/MAG welding processes for pipes with diameters ≥140 mm and wall thicknesses between 4 mm and 60 mm.
