Shop Floor Ready Floor-Mounted Column and Boom Welding Manipulator for Longitudinal & Circumferential Cylinder Welding

The LT-MZ1222 floor-fixed column and boom welding manipulator is a professional automated welding system purpose-built for mass production of cylindrical workpieces. Its heavy-duty floor installation design delivers ultra-high structural stability, zero shaking during operation, and precise mechanical movement.

Paired with welding turning rolls, it forms a complete automatic welding workstation covering two core processes: longitudinal straight seam welding and circumferential girth seam welding. It effectively eliminates the unstable quality, low efficiency, and high defect rates associated with manual welding in tank, pressure vessel, and pipe fabrication.

Supporting multiple welding processes including submerged arc welding and gas shielded welding, the manipulator is widely used for carbon steel, stainless steel, and alloy steel welding. It is the most cost-effective automatic welding equipment for medium and large welding workshops.

The cylindrical shell is fixed on the turning rolls. The boom drives the welding head to move horizontally at a constant speed, realizing continuous and uniform full-length straight seam welding for tank shell courses and cylinder plates.

The workpiece rotates at a constant speed while the welding head remains fixed, forming high-precision closed circular welds for pressure vessel barrel joints, pipe spool girth seams, and cylindrical component butt joints.

Floor-fixed rigid structure combined with constant-speed mechanical movement eliminates welding jitter and track deviation. The weld bead is flat, penetration is uniform, and the NDT inspection pass rate is significantly improved.

Dual functions of longitudinal and circumferential welding meet all welding needs of cylindrical workpieces, greatly improving equipment utilization and reducing factory procurement costs.

Intelligent recipe switching and fully automatic welding replace manual operation, enabling batch continuous production and effectively shortening project delivery cycles.

The stress-relieved industrial structure resists deformation and fatigue. The equipment runs stably for long periods with a low failure rate and requires only simple daily maintenance.

Compatible with all mainstream welding power sources and turning rolls on the market, suitable for various sizes of tanks, vessels, and pipe workpieces.

Widely used in pressure vessel manufacturing, boiler processing, large storage tank fabrication, pipe spool prefabrication, chemical equipment, and environmental protection cylindrical steel structure production.

The LT-MZ1222 floor-fixed welding manipulator is a high-stability, high-efficiency, and multi-functional automatic welding solution. With solid floor installation, rigid industrial structure, and intelligent control system, it helps welding workshops achieve standardized welding quality, automated production, and lower manufacturing costs, making it the preferred automation equipment for cylindrical workpiece welding.
