Product Overview
Solve your business pain points with innovative technical solutions
The HJ series cantilever automatic welding machine for longitudinal and circumferential seams of cylinders is mainly used for longitudinal seam welding of pressure vessel shells after plate rolling, circumferential seam welding for extending two or more shell sections, and circumferential seam welding between shells and heads or flanges. The system consists of a cross-type cantilever welding manipulator, powered turning rolls and welding power source, etc. For circumferential seams, the turning rolls drive the workpiece to rotate while the welding torch remains relatively fixed to weld the circumferential seam; for longitudinal seams, the workpiece is stationary and the cantilever boom of the welding manipulator extends and retracts to move the torch along the longitudinal seam. It is ideal equipment for pressure vessel fabrication.
