PLC CNC Pipe Longitudinal Seam Welder 0.4–8mm Thin Wall Pipe Duct Welding Machine

This 1000mm Pipe Longitudinal Seam Welding Machine is designed for longitudinal welding of metal pipes, tubes and air ducts. Equipped with piano key pneumatic clamping and water cooling copper backing bar, it supports TIG/MIG welding with low deformation and one-time double-side weld forming. PLC touch screen control ensures stable welding quality, perfect for mass pipe production with CE certification.

• Professional pipe dedicated design, matched clamping stroke fits all kinds of pipe plates
• Low thermal deformation, uniform clamping and cooling system prevent thin pipe warping
• Single-side welding double-side forming, smooth inner and outer welds to avoid pipeline leakage
• Servo constant-speed driving guarantees consistent weld width and penetration within 1000mm stroke
• Multi-direction adjustable torch, flexible for different pipe diameters and plate thickness

• Industrial PLC with strong anti-interference, stable for long-time continuous pipe welding
• 7-inch touch screen, easy parameter setting and one-click recall of saved pipe welding programs
• Full automatic welding logic: auto arc striking, constant travel and crater filling for neat pipe seams
• Real-time fault alarm system to quickly locate problems and reduce production stop time

This Pipe Longitudinal Seam Welding Machine can link multiple equipment to build full automatic pipe production line.

• Link with welding rotators: Finish continuous longitudinal and circumferential welding of tubular products
• Link with CNC cutting machine: Complete cutting, rolling and longitudinal welding integrated production
• Link with 3D welding table & clamps: Accurately fix special pipe fittings to prevent welding deviation
• Link with welding positioners: Remove welding dead angles for uniform weld appearance
