LT-MZ1222 Column Boom Welding Manipulator, Automated Welding System for Heavy Pressure Vessel Shells on Turning Rolls

The LT-MZ1222 adopts a mature and reliable relative motion welding principle for cylindrical workpieces.

For circumferential girth seam welding, the heavy tank or vessel shell is placed on welding turning rolls. The rolls drive the workpiece to rotate at a constant, adjustable speed while the welding manipulator fixes the welding torch at the precise weld position. The stationary torch and uniformly rotating workpiece ensure continuous, smooth and fully fused circular welds with consistent penetration around the entire shell.

For longitudinal straight seam welding, the horizontal boom moves steadily along a preset track at constant speed, completing precise straight seam welding for cylinder plate splicing.

All welding speed, torch position and welding trajectory are mechanically fixed and digitally controlled, eliminating manual errors and ensuring stable weld quality in long-term batch production.

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

• Pressure vessel and boiler manufacturing industry
• Petroleum, chemical and environmental protection storage tank production
• Large-diameter steel pipe and pipeline engineering fabrication
• New energy equipment, pressure cylinder and container processing
• Heavy steel structure cylindrical workpiece welding

The LT-MZ1222 welding manipulator is an essential automated upgrade solution for traditional vessel welding workshops. It realizes standardized, high-efficiency and high-quality welding production, solves the problems of unstable manual welding quality and labor shortage, and significantly improves product qualification rate and enterprise market competitiveness.

With stable performance, strong adaptability and long service life, it provides long-term reliable production capacity and high return on investment for industrial welding manufacturers.
