Automatic 1500mm Longitudinal Straight Seam Welding Machine For Tank Pipe

Our 1500mm longitudinal straight seam welding machine is an automatic longitudinal welding device independently developed for diversified metal processing demands. With a maximum valid welding length of 1500mm, it breaks the limitation of single workpiece processing. Its high compatibility for materials and workpieces allows one unit to satisfy production needs across dozens of manufacturing sectors. Whether for small batch customized processing or large-scale assembly line manufacturing, this straight seam welder can deliver stable, high-precision welding performance, becoming core standard equipment for modern sheet metal and tank factories.

To realize full-cycle cylinder processing and expand your production range, this straight seam welder can be matched with our complete welding auxiliary equipment:

• Self-align welding rotator: Complete circumferential welding after longitudinal seam forming, achieving finished tank production in one full line.
• Custom positioning fixture: Fix short flat plates and tiny cylinders, expanding the processing capacity of small customized orders.
• Automatic welding manipulator: Realize synchronous follow-up welding for mass production lines of large-scale tank manufacturers.

• Ultra-wide compatibility: No need to purchase multiple welding machines for different products, greatly lowering workshop equipment investment cost.
• Pneumatic integral piano-key clamping system: Even pressure avoids thin plate deformation and surface scratches, ideal for high-demand stainless steel sanitary products.
• Stepless variable welding speed: Flexible speed adjustment to switch between delicate thin-plate welding and heavy-duty medium-plate structural welding.
• Reinforced overall frame: Adopts stress-relief thick steel welding structure, stable performance under long-time heavy-load production.
• Fast parameter switching panel: Operators can finish parameter adjustment within minutes when replacing workpieces, cutting downtime for mixed batch production.

• Pressure Vessel Production: Small storage tanks, heat exchanger barrels, low-pressure equipment shells and filter cylinder longitudinal welding
• New Energy & HVAC Manufacturing: Solar water tank barrels, heat preservation containers, industrial ventilation pipes and energy storage equipment casings
• Auto & Hardware Machining: Automobile muffler shells, fuel tanks, exhaust pipes and hydraulic pipe fittings
• Electrical Equipment Fabrication: Transformer housings, electrical control cabinet shells and metal support frames
• General Sheet Metal Processing: Sanitary kitchenware, environmental protection equipment shells and craft cylindrical parts
