Automatic Column and Boom Seam Welding Manipulator | Precise, Stable & Efficient Welding for Industrial Pipes and Pressure Vessels

The main column and boom are constructed from thickened national standard rectangular steel pipes. After full integral welding, the entire frame undergoes high-temperature stress relief annealing to completely eliminate internal welding stress. All contact surfaces are processed by four-axis CNC gantry precision milling, ensuring overall flatness, verticality and structural rigidity.

The frame will never deform, shake or deflect during long-term continuous high-frequency operation, providing an ultra-stable mechanical foundation for high-precision seam tracking and consistent weld forming.

The horizontal boom adopts an optimized box-type anti-bending and anti-torsion structure, equipped with high-precision linear guide rails and silent rolling sliding pairs for smooth, uniform telescopic movement free of jitter, pause and deviation.

The maximum effective working stroke reaches 2000mm, fully meeting the welding requirements of most medium-diameter tank bodies, barrel shells and long straight seams. The stable walking track keeps the welding torch moving at constant speed, avoiding weld ripples and uneven bead width.

The vertical lifting effective stroke is 2000mm, supporting large-range height adjustment to freely adapt to different roller frame heights, workpiece sizes and multi-layer multi-pass welding height requirements.

The lifting system uses an industrial worm gear reducer plus synchronous heavy-duty chain dual drive structure. Power output is balanced and stable, with no sliding down, no jamming and no shaking during operation, guaranteeing consistent welding height and uniform heat input for every welding layer.

The base adopts a thickened integral cast steel structure with strong compression resistance and anti-vibration performance, supporting 360° free manual rotation of the entire column and boom assembly.

Workers can adjust the welding direction and working angle arbitrarily according to workpiece placement without moving heavy tanks or barrels. This greatly improves workshop operation flexibility, enables multi-station cross-use of a single machine and maximizes the utilization rate of limited factory space. An electric automatic rotation system is available as an optional upgrade for intelligent production lines.

Both horizontal boom travel and vertical column lifting adopt industrial stepless speed regulation technology with a precise and wide adjustment range. Operators can set low speed for fine welding and high speed for empty stroke return, greatly improving overall production efficiency.

Constant mechanical running speed completely eliminates manual speed fluctuation, effectively solving common welding defects such as weld ripple, undercut, burn-through, incomplete penetration and inconsistent weld bead height.

The professional welding torch clamping unit supports six-dimensional precise adjustment: up, down, left, right, forward and backward linear displacement plus 360° angle rotation adjustment.

According to different plate thickness, groove angle, weld gap and welding process parameters, operators can accurately calibrate arc length, torch inclination and welding offset position to achieve perfect seam fitting, ensuring repeatable high-standard welding quality for mass production.

All welding cables, control signal lines, power lines and gas delivery pipelines are fully hidden and protected in high-toughness engineering plastic energy chains.

The fully enclosed structure effectively avoids wire stretching damage, friction aging, pipeline loosening and gas leakage caused by long-term reciprocating movement, greatly improving equipment safety, operational stability and overall service life while reducing daily failure rate.

The 2000mm double-stroke design provides super-wide working coverage, covering almost all conventional medium-sized cylindrical workpieces. The machine is compatible with all mainstream welding machines and welding rotators on the market, realizing both longitudinal seam and circumferential seam welding functions. One machine replaces multiple traditional pieces of equipment, greatly saving factory procurement cost.

Unlike fixed manipulators with a single working direction, the full rotary base enables multi-angle flexible operation. It does not limit workpiece placement direction, enables multi-station cross operation and significantly improves workshop space utilization and production efficiency.

Automated constant-speed mechanical walking replaces manual operation errors. The weld seam features uniform width, stable penetration depth, a flat and smooth surface, and no pores, slag inclusion, cracks or welding deformation. It reduces post-weld polishing and repairing workload by more than 70%, perfectly meeting industrial and sanitary grade welding standards.

The humanized intelligent remote control operation system features simple logic and intuitive buttons. Ordinary workers can operate skillfully after short-term training, completely removing dependence on high-paid senior welders. It effectively solves the industry pain points of welder shortage, high labor cost and unstable manual quality.

Although equipped with a large working stroke, the overall structure is compact and does not occupy excess workshop area. No complicated foundation construction is required. The equipment can be installed, debugged and put into formal production in a short time, suitable for processing workshops of all sizes.

The whole machine adopts a thick industrial steel structure and standardized universal accessories. All moving parts are treated with anti-rust, anti-corrosion and anti-wear processes. Long-term continuous industrial operation is stable and reliable with an ultra-low failure rate. Spare parts are universal and easy to purchase, greatly reducing later maintenance time and economic loss.
