Fixed Longitudinal Seam Welding Machine
The Fixed Longitudinal Seam Welding Machine is a high-precision, automated solution engineered for the longitudinal seam welding of cylindrical, conical, and plate workpieces. Integrated with advanced P+T (Plasma + TIG) Welding System Technology, this machine delivers superior one-side welding with back formation, ensuring high efficiency, consistent quality, and excellent weld aesthetics for stainless steel, carbon steel, and alloy steel materials.
Key Features
- High-precision Clamping System: Equipped with a heavy-duty clamping mechanism and adjustable mandrels (round/square), ensuring secure workpiece fixation and consistent seam alignment.
- Adjustable Centering & Finger Clearance: Fine-tunable centering device and finger clearance adjustment (5~40mm) accommodate various workpiece diameters and thicknesses.
- Variable-Speed Travel Carriage: The welding carriage runs smoothly at adjustable speeds (60~1200 mm/min) to match different material and thickness requirements.
- Modular Design: The machine is available in multiple models (JZF1500/JZF2000/JZF3000) to suit different workpiece lengths, diameters, and production scales.
- Easy Operation & Maintenance: User-friendly control interface and modular components simplify setup, operation, and routine maintenance, reducing downtime.
