Column and Boom Automatic Welding Manipulator, Industrial Welding Equipment for Tank & Pipe Longitudinal and Circumferential Welds

The Column and Boom Automatic Welding Manipulator is a heavy-duty industrial welding system engineered for full-automatic longitudinal and circumferential seam welding of large cylindrical workpieces. It is a core equipment solution for pressure vessel manufacturing, boiler production, storage tank fabrication, large-diameter pipe processing and chemical steel structure industries.

Traditional manual workshop production struggles to control long seams and circular seams on tanks and pipes. Manual welding causes inconsistent weld width, uneven penetration, poor straightness, frequent defects, high rework rates and low production efficiency. High-quality pressure vessel products also demand stable, traceable and standardized welding processes that manual operation cannot deliver.

This automatic welding manipulator solves those industry pain points. By combining vertical column lifting, horizontal boom extension, precise torch fine-tuning and a PLC automatic control system, it delivers fully mechanized and standardized welding of longitudinal straight seams and circumferential circular seams. Matched with pipe turning rollers and welding power sources (SAW / MIG / MAG), it forms a complete automatic tank welding workstation that greatly improves welding consistency, penetration stability and overall workshop output.

Suitable for both small-batch customized production and large-scale mass production, this manipulator has become essential standard equipment for modern heavy industry welding workshops.

The whole welding manipulator adopts a heavy-duty integral steel plate welding structure, including a vertical rigid column, telescopic welding boom, vertical lifting system, horizontal travelling mechanism, multi-direction torch fine adjustment device, electric control system, cable drag chain protection and safety limit system.

The vertical column provides stable vertical support and precise lifting movement. The horizontal boom carries the welding torch and extends forward to cover the workpiece welding area. Cooperating with the rotating roller bed, the workpiece rotates at a uniform speed while the manipulator keeps the welding torch fixed at an accurate position. Continuous and uniform welding speed ensures consistent weld formation, stable penetration and an extremely low defect rate.

• Longitudinal seam welding: the boom moves horizontally at a constant speed to complete straight long seam welding.
• Circumferential seam welding: the workpiece rotates steadily while the torch remains fixed to finish perfect circular welding.

• Heavy-duty column and boom: thickened integral welded steel structure with high rigidity, low vibration and no deformation during long-term heavy-load operation.
• Precision lifting system: gear-rack driving mode ensures stable lifting, no jitter and accurate height positioning.
• Horizontal telescopic boom: smooth feeding movement and uniform speed, ensuring straight and neat long weld seams.
• Multi-angle torch fine adjustment: micro-adjustment in X, Y and Z directions allows precise alignment for complex seams and irregular workpieces.
• Full protection drag chain: all cables and air pipes are protected inside drag chains to avoid pulling, abrasion and aging during repeated movement.
• Full safety system: equipped with upper and lower travel limit switches, emergency stop button and anti-collision protection to ensure safe industrial operation.

This automatic welding manipulator is widely used in heavy industrial manufacturing fields:

• Pressure vessel & boiler manufacturing industry
• Large storage tank and oil tank production
• Chemical equipment cylindrical workpiece processing
• Municipal engineering large-diameter steel pipe welding
• New energy, environmental protection and heavy steel structure fabrication

It is specially suitable for longitudinal seam welding of cylinder plates and circumferential seam welding between cylinder sections, cylinder heads and pipe joints.

For tank, pipe and pressure vessel manufacturers, this column and boom welding manipulator realizes standardized, automated and intelligent upgrading of traditional welding workshops.

It stabilizes product quality, improves pass rate, shortens delivery cycles and solves the problems of difficult recruitment, high labor cost and unstable manual welding quality. Its durable structure, low maintenance rate and strong compatibility provide factories with long-term stable production capacity and higher market competitiveness in heavy industrial manufacturing.

It is the most cost-effective and essential automatic welding equipment for modern large-scale cylindrical workpiece production lines.
