Head-tail Welding Positioner is a special welding auxiliary machine for circumferential seam welding of long cylinders, hydraulic cylinders, long shafts and other workpieces. It serves as the core supporting equipment for automatic welding production lines of pressure vessels, construction machinery and pipeline fabrication.

The machine adopts an integrated heavy-duty bed frame with high rigidity and strong deformation resistance. The driving headstock is equipped with a precision three-jaw chuck, delivering stable torque output and stepless speed regulation to rotate the workpiece smoothly. The tailstock can slide freely along the bed guide rail to flexibly adjust the supporting span, suitable for workpieces of different lengths with convenient clamping and great adaptability. During operation, it can automatically rotate the circumferential seam of the workpiece to the flat welding position, avoiding forming defects caused by overhead welding and vertical welding, effectively improving weld quality and reducing the difficulty for welders.

This positioner features high rotation accuracy, low operating vibration and a wide speed regulation range. It is perfectly compatible with submerged arc welding, TIG welding and welding robot systems for automated continuous welding. With a mature transmission structure, easy maintenance and low failure rate, it can stably carry heavy long cylindrical workpieces to meet mass and continuous production requirements.
It is widely used in the processing of pressure vessels, hydraulic cylinders, conveyor rollers, pipeline components, cylindrical parts of construction machinery and so on, helping enterprises improve welding automation, shorten production cycles and stabilize welding quality.
