1200mm Automatic Longitudinal Straight Seam Welding Machine for Stainless Steel Cylinder

1200mm effective welding stroke automatic longitudinal seam welder, pneumatic full-length clamping + copper cooling fixture, minimal welding deformation, compatible with TIG/MIG welding power source, perfect for stainless steel tank, water tank, pipeline cylinder mass production, CE certified, factory direct customization available.

• Weld Quality Standardization: Uniform weld bead width & penetration rate, reject rate of longitudinal seam reduced by over 80% compared with manual welding, meet pressure vessel non-destructive testing standards.
• Labor Cost Reduction: Only one operator for feeding & unloading, cancel skilled senior welders for straight seam operation, greatly cut labor salary expenditure.
• Shorten Production Cycle: Continuous automatic welding, production efficiency increased 3-5 times vs manual welding, support order rush delivery.
• Low Post-Workload: Small welding deformation, less grinding & shaping work after welding, save post-processing time and abrasive.

• Main machine frame fixed with high-strength steel wire, electrical cabinet and precision fixtures packed with fumigated wooden case for sea freight anti-collision protection
• Complete operation manual, wiring diagram, parameter setting guide and vulnerable spare parts attached
• Professional container loading layout design, provide detailed packing list for buyer customs clearance
• Support FOB, CIF, DDP international trade terms, coordinate door-to-door delivery service

Combine this straight seam welder with our other welding equipment to build a full-automatic cylinder tank production line, greatly improve overall workshop productivity:

• Welding Rotator / Fit-up Rotator: Complete circumferential seam welding after longitudinal seam forming, realize full circumference welding of tank body.
• Welding Positioner: Used for head flange assembly and auxiliary welding of tank bottom and tank mouth.
• CNC Plasma Cutting Machine: Cut cylinder blank steel plate accurately for subsequent straight seam splicing.
• Welding Manipulator: Match with rotator for long vessel outer circle automatic submerged arc welding.
• Hydraulic Tank Head Spinning Machine: Process tank end caps, form complete tank assembly production flow.

A1: It is suitable for plates from 0.6mm to 6mm, covering thin stainless steel plates, carbon steel and aluminum plates for water tanks and pressure vessels.

A2: Yes. The machine is compatible with mainstream TIG, MIG and MAG welding power sources. We can reserve the interface according to your welder brand and model.

A3: Standard effective welding length is 1200mm. We support customized lengthened or shortened travel stroke to match your cylinder height requirements.

A4: Equipped with full-length pneumatic compression and back water-cooled copper liner for rapid heat dissipation, which effectively controls thermal deformation and realizes single-side welding double-side forming.

A5: Perfect matching. After longitudinal seam welding, place the cylinder on welding rotator for circumferential welding to finish the whole tank body fabrication.
