Rotary Welding Manipulator (Fixed Belt Column Boom Manipulator)

1. The column and boom are manufactured with cold-formed welded type structure. After the annealing process and finish machining, they possess fine rigidity and strength.
2. To ensure safety operation of the rotary welding manipulator, the boom lifting device uses a ratchet-and-pawl structure and is equipped with a fall protection device.
3. Frequency control is applied for the adjustment of retracing speed, greatly improving the reliability and stability of the welding manipulator operation.
4. The front end of the boom is manufactured with a cross adjustment structure which can be adjusted through the manual control box.
5. The eight guide wheels all utilize eccentric structure. During installation and set up, the lead rail tension can be adjusted by using the eccentric shaft. After this adjustment, the rail should be locked with double nuts.
6. The column rotation can be carried out with manual and electric control then locked.

7. The electrical equipment includes a manual control box and electric cabinet.

8. The optional equipment of the rotary welding manipulator includes trolley, manned seat and worktable, drag chain, seam tracing and monitoring system, and flux recovering system.


The welding manipulator, also called fixed belt column boom manipulator, is used for the automatic welding of internal and external circular seams, and internal and external longitudinal seams of steam drums and other cylindrical pieces in the boiler, pressure container, oil, machinery manufacturing industries and in the chemical industry.

1. To ensure a safe connection, the rotary welding manipulator should be grounded and reliably connected using the correct voltage. Should a problem arise, the power supply should be cut off immediately and the equipment inspected and repaired before operating the machine.
2. Wiring located outside the equipment should be inspected for faculty connection. If a problem arises with the cable insulation, the equipment should be immediately stopped and overhauled.
3. Welding should be performed in strict compliance with safety regulations and protective equipment must be worn while operating the rotary welding manipulator.
4. The joint of the multicore cable should be inspected. If loose, it may cause poor contact and affect welding operation. To avoid breakage, the welding cable should not be twisted too often.
5. Should a problem arise with the cable insulation, the machine must be immediately shut off and overhauled.
6. The rotary welding manipulator should be operated in an area free from rainwater, corrosive gas and high temperature to avoid causing damage to electronic components or affecting operation functionality.
7. A special power supply is required if frequent fluctuation of main voltage exists.
