Product Overview
Solve your business pain points with innovative technical solutions
This HJ series cantilever automatic welding machine for cylindrical shell longitudinal and circumferential seams is mainly used for longitudinal seam welding after pressure vessel shells are rolled from steel plates; circumferential seam welding for joining two or multiple shell sections; and circumferential seam welding between shells and heads/flanges. The equipment consists of a cross cantilever welding machine, a driven welding rotator (roller bed), welding power source, etc. It uses the roller bed to drive the workpiece to rotate, with the welding torch relatively fixed for circumferential seam welding; for longitudinal seams, the workpiece remains stationary, and the cantilever of the cross cantilever welding machine extends/retracts to move the torch for welding. It is an ideal piece of equipment for pressure vessel fabrication.
