As a core intelligent piece of equipment for modern steel bar processing, our Rebar Cage Rolling Welding Machine is engineered for high-standard, large-scale rebar cage production, and is widely applied in global key infrastructure projects including high-speed railways, expressways, bridges and tunnels, rail transit, nuclear and hydropower projects, as well as professional steel bar processing and distribution centers. Designed to completely replace traditional manual binding and semi-automatic welding, this machine integrates advanced PLC frequency conversion control, servo drive technology, and intelligent welding systems, realizing fully automated production from main bar feeding, positioning and welding to stirrup winding, forming and finished cage output, with no manual intervention required in the entire welding process—fundamentally solving the industry pain points of low efficiency, unstable quality, and high labor costs in traditional rebar cage production.

The machine consists of a high-precision automatic main bar feeding system, a laser positioning and welding system, a dual-gun synchronous rolling welding system, a stirrup tensioning and winding system, and an intelligent rebar cage forming and positioning system. The whole operation is driven by a PLC control system and multi-frequency converter coordination, which ensures perfect synchronization of all motor movements. This precise control not only guarantees the stable forming of rebar cages but also maximizes welding efficiency: the welding time for a single main bar is less than 35 seconds, and a standard 9-12m rebar cage skeleton can be fully welded and formed in just 20 minutes. Compared with manual welding, the machine saves more than 80% of labor costs and improves overall production efficiency by 5-8 times. What’s more, the welding time of each solder joint can be flexibly configured and saved according to different process requirements and rebar specifications, eliminating efficiency loss caused by repeated manual adjustment and supporting continuous and uninterrupted production to meet the tight construction schedules of large infrastructure projects.
Superior and stable welding quality is the core competitiveness of this equipment. Adopting a full-closed-loop control system and high-precision pressure and position sensors, it accurately controls welding current, voltage, time and position, completely eliminating common welding defects such as false welding, missing welding and weld porosity. The uniform weld penetration ensures the tensile strength of each joint exceeds international engineering standards, laying a solid foundation for the structural safety of concrete pile foundations. Meanwhile, the intelligent welding parameter optimization algorithm effectively reduces the waste of welding materials by 15% compared with traditional equipment, achieving the dual goals of quality assurance and cost reduction. The machine has a strong adaptability to rebar specifications: it can process rebar cages with a diameter of 400mm~2500mm, and flexibly complete the welding of single main bar with single stirrup, single main bar with double stirrup and double main bar with double stirrup, fully meeting the diverse production needs of different projects.
Operation convenience and humanized design are fully reflected in every detail of the machine. It is equipped with a high-definition touch screen operation panel, which supports the presetting and permanent storage of multiple sets of rebar cage specification parameters (including cage diameter, length, main bar spacing, stirrup density, etc.). During production, workers only need to invoke the pre-stored data with one click and start the operation—no professional programming skills are required, and new operators can master the whole operation process after short-term systematic training. This effectively solves the problem of labor shortage and skill gap in the construction industry, and realizes the assembly-line production of rebar cages with simple and intuitive operation. In addition, the machine has undergone structural optimization and upgrading in key parts: the rim structure adopts high-strength seamless steel pipe with precision cold forming, which increases the contact area with the supporting roller and greatly reduces the operating inertia, making the equipment run more stably with lower noise during heavy-load production; the quick-change template design allows the replacement of molds for different cage specifications in only 1 hour, greatly shortening the production switching time and improving the overall production efficiency of multi-specification small-batch production.
To meet the strict quality requirements of global infrastructure projects, the machine is equipped with a full-process real-time monitoring and data recording system. All equipment operation information, welding parameters, processing time and joint quality are automatically monitored, detected and recorded in real time during production. If abnormal parameters or equipment faults are found, the system will immediately issue an audible and visual alarm and stop the operation to avoid unqualified products. This intelligent monitoring system not only ensures the stability and consistency of rebar cage processing quality but also provides complete and traceable production data for project quality inspection and acceptance, reducing the on-site inspection workload of project supervisors by more than 90%. The machine is manufactured with high-strength steel integral welding, and its modular structure design facilitates daily maintenance, component replacement and on-site installation. It can also be customized according to customer needs, such as lengthening the equipment to process 18-22m extra-long rebar cages, or adding a traction device for heavy rebar cage production, adapting to different working conditions such as high temperature, high humidity and heavy load.
