Automatic Half-Pipe Jacket Welding at Zhongtian Petrochemical Machinery

Quanzhou Zhongtian Petrochemical Machinery adopted a haibao robot automatic welding system for half-pipe jackets on reactors. The project focuses on maintaining torch position along complex jacket seams while reducing dependence on continuous manual adjustment.

From manual guidance to repeatable motion

Half-pipe jackets require the torch to follow the joint as the vessel geometry changes. Long manual welds place sustained demands on operator concentration and can vary between shifts. Automatic motion and seam tracking help maintain a more consistent relationship between torch and joint.

TIG welding with seam tracking

The described equipment uses argon-shielded TIG welding and sensor-based seam tracking. The system monitors joint position and adjusts the torch path during welding. The process is selected to support controlled heat input and a clean weld surface on suitable reactor materials.

Reported workshop benefits

The original project account reports shorter welding time, reduced manual intervention and more consistent weld quality after the equipment was introduced. It does not provide a sufficiently complete automated cycle-time dataset for a transferable productivity guarantee. Final output estimates should include vessel handling, setup, the complete weld sequence and inspection.

Evaluate the whole jacket process

Forming accuracy and half-pipe fit-up influence the work required during welding. Before automation, review jacket pitch, contact with the shell, start and end details, access near heads and nozzles, shielding and the required inspection method. A representative trial provides a stronger basis for selection than a nominal travel-speed figure alone.
