Automated Circumferential Joint Welding Manipulator for Pipe Spool Production, Ideal for Large Pipe, Pipe Spool and Pipe Rack Manufacturing

The vertical column and welding boom are fabricated with thick industrial steel plates and undergo professional stress relief treatment. The rigid frame minimizes vibration and structural deformation during long-duration heavy-load welding, maintaining ultra-stable torch positioning and high welding precision.

Equipped with a motor-driven gear-rack lifting mechanism, the boom achieves smooth, accurate and jitter-free vertical height adjustment. The frequency conversion horizontal travelling system provides stepless speed regulation, adapting to different pipe diameters, wall thicknesses and welding procedure requirements.

The welding torch holder supports X, Y, Z three-direction micro-adjustment. Operators can accurately calibrate the torch aiming center for irregular pipe gaps, pipe ovality and multi-layer multi-pass welding, ensuring perfect seam alignment and stable fusion.

Featuring industrial PLC control and a high-definition touch screen interface, the system supports real-time parameter adjustment, multi-group welding recipe storage and one-click parameter recall. Users can store standard welding data for common pipe sizes, realizing fast production switching and continuous automated operation.

All power cables, control lines and air pipelines are protected by heavy-duty industrial drag chains. This design prevents cable stretching, abrasion and aging caused by repeated mechanical movement, improving equipment stability and service life.

Built with upper and lower stroke limit switches, front and rear travel limit protection, emergency stop button and mechanical anti-collision devices. It effectively prevents overtravel, collision and operational faults, ensuring safe and stable operation in intensive industrial workshop environments.
