Product Overview
Solve your business pain points through innovative technical solutions
This HJ series cantilever-type shell longitudinal and circumferential seam automatic welding machine 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 equipment consists of a cross-type cantilever welding machine, driven welding rotator, welding power source, etc. For circumferential seams, the rotator drives the workpiece to rotate while the welding torch remains relatively fixed to weld the circumferential seam; for longitudinal seams, the workpiece remains stationary and the cantilever of the cross-type welding machine extends and retracts to perform longitudinal seam welding. It is an ideal piece of equipment for pressure vessel manufacturing.

| Welding Method |
The workpiece rotates while the welding torch is positioned at the internal/external welding position of the workpiece for circumferential seam welding.
For longitudinal seams, the workpiece remains stationary and the extension/retraction of the cantilever of the welding machine drives the welding torch to move for welding.
