Lifting Type Longitudinal Seam Welding Machine
The JSJZF Series Lifting Type Longitudinal Seam Welding Machine is a heavy-duty, automated welding solution designed for large-diameter, extra-long cylindrical and tank workpieces. Built with a vertical lifting mechanism and high-precision welding carriage, it delivers consistent, high-quality longitudinal seam welds for pressure vessels, large storage tanks, petrochemical equipment, and heavy industrial pipelines.
Core Advantages
Vertical Lifting Design: The adjustable lifting stroke (3000/4000/5000mm) accommodates extra-large workpieces up to φ5000mm in diameter, solving the challenge of welding oversized cylindrical parts.
High-Speed Welding Capability: The traveling carriage speed ranges from 50~5000 mm/min, supporting both high-speed production for thin plates and stable welding for thick workpieces (up to 12mm).
Reliable Clamping System: Heavy-duty clamping mechanism with adjustable finger clearance (5~40mm) and 30 kgf/cm single-side clamping force ensures secure fixation of large workpieces, preventing deformation during welding.
Versatile Compatibility: Works seamlessly with carbon steel, stainless steel, and alloy steel, suitable for a wide range of industries including pressure vessels, chemical tanks, and new energy equipment.
Automated Operation: Integrated with precision control systems, it reduces manual intervention, ensures consistent weld quality, and lowers labor costs for mass production.
