Product Description

LT-MZ1222 Welding Column and Boom Manipulator

The LT-MZ1222 welding column and boom manipulator is a modular automatic welding system engineered for heavy fabrication workshops producing cylindrical metal components. Paired with welding turning rolls, it forms a complete workstation that automates longitudinal straight seams and circumferential girth seams on tank shells, pressure vessel barrels, and large pipe spools.
Every component is designed as a coordinated module. The main column, travel carriage, telescopic boom, welding head, flux hopper, and control cabinet work together to deliver steady, repeatable weld quality. The system eliminates the inconsistency of manual welding and helps manufacturers increase output while keeping defect rates low. It supports submerged arc welding (SAW), MIG, MAG, and CO₂ gas shielded welding, and is compatible with carbon steel, stainless steel, and low alloy steel.

Modular Component Breakdown

Vertical Column

Constructed from thick steel plate and fully stress-relieved after welding. It forms the rigid backbone of the system, fitted with precision vertical guide rails. It suppresses vibration during lifting movement to keep the welding assembly stable.

Travel Carriage

Mounted on the column rails and driven by a gear-rack mechanism. The carriage carries the boom assembly up and down, adjusting welding head height to accommodate workpieces of different diameters.

Telescopic Boom

Heavy-duty rectangular box beam with anti-torsion properties. It extends horizontally and travels at adjustable constant speed. It carries the welding head and flux feeding assembly, delivering linear movement for long straight seam welding.

Welding Head

Equipped with X/Y/Z three-axis torch fine adjustment. Operators can fine-tune torch position to align precisely with weld grooves, compensating for assembly gaps and plate misalignment during multi-layer welding.

Flux Hopper

Purpose-built for submerged arc welding. It stores flux and feeds it continuously during SAW operation, shielding the molten weld pool and creating deep penetration, high-quality welds.

Independent Control Cabinet

Houses a PLC and touch screen HMI. Operators can adjust travel speed, store welding recipes, control all machine movements, and activate safety interlocks from this centralized control unit.

Two Working Modes

1. Longitudinal Straight Seam Welding

The cylindrical shell stays fixed on turning rolls. The boom drives the welding head horizontally along the full length of the straight seam, producing uniform long welds for rolled shell courses.

2. Circumferential Girth Seam Welding

The workpiece rotates on turning rolls while the boom and welding head remain stationary. Continuous rotation creates full-circle ring welds for vessel barrels and pipe joints.

Product Strengths

Modular Design for Easy Installation & Maintenance — Individual assemblies can be inspected and serviced separately. The clean layout simplifies daily maintenance and reduces downtime.
Dual Welding Functions Maximize Machine ROI — One machine handles both straight and circular welds for cylindrical products, eliminating the need to purchase separate machines for different welding processes.
Stable Mechanical Performance — The stress-relieved rigid frame minimizes vibration during operation, ensuring consistent weld bead appearance and penetration for high NDT pass rates.
Recipe Storage for Fast Production Changeover — Save welding parameters for different plate thicknesses and materials. Switching between jobs takes only a short time, improving workshop productivity.
Flexible Compatibility — Works with most mainstream welding power sources and turning rolls. It can be used as a standalone cell or integrated into full automatic production lines.
Reduced Reliance on Skilled Welders — Automated movement ensures stable weld quality. Less manual intervention means fewer reworks, less grinding, and lower overall manufacturing costs.

Application Industries

Pressure vessel and boiler manufacturing
Large storage tank and silo production
Pipe spool prefabrication
Petroleum, chemical, and environmental equipment fabrication
Heavy cylindrical steel structure manufacturing

Conclusion

The LT-MZ1222 welding column and boom manipulator is a flexible modular automation solution for cylinder fabrication. Its robust modular structure, dual welding capability, and intelligent control make it a smart investment for workshops aiming to upgrade welding consistency and production capacity.
