Concrete Pipe Cage Welding Machine

Description of Diameter-variable Roll Welding Machine
This roll welding machine, often referred to as cage welding machine, is specially designed for welding the reinforcement cage framework used in concrete drainage pipes.

Features of Diameter-variable Roll Welding Machine
1. The diameter is varied online automatically, controlled by PLC.
2. The welded cage framework can be for flat joint, tongued & grooved joint, bell & spigot joint concrete pipes.
3. In full stroke, the diameter can be varied automatically and shifted very quickly
4. Special designed synchronizer to ensure no twist on the formed framework
5. Auto alarm for faults and misoperation
6. Imported PLC, inverter, encoder and touch screen
