Rebar Cage Welding Workstation
1. Fully Automatic & Unmanned Operation: Integrates automatic longitudinal bar welding and spiral winding welding in one system, enabling true unmanned production with only 1–2 operators required.
2. High Efficiency & Large Output Capacity: A 9–12 m cage can be completed within 20–25 minutes, with significantly higher shift output compared to traditional rolling welding machines.
3. Precision Control & Superior Welding Quality: CNC positioning, automatic CO₂ gas shielded welding, and real-time monitoring ensure accurate alignment (±3 mm) and stable weld quality with no false or missed welds.
4. Flexible Configuration & Intelligent Management: Supports wide diameter range (800–2500 mm) without mold change, stores up to 30 cage parameter sets, and enables one-touch operation via touchscreen for fast specification switching
Product Introduction
The Rebar Cage Welding Workstation YGTZ2500-12 is a fully automatic rebar cage welding system developed with independent intellectual property rights. It is widely used in metro construction, bridges, residential and commercial buildings, airports, highways, and foundation engineering projects.
The equipment consists of an automatic longitudinal bar feeding system, main bar detection and positioning welding system, spiral bar winding and welding system, and cage discharge system. The entire welding process is completed automatically without manual intervention.
With high production efficiency, the welding time for a single longitudinal bar is less than 35 seconds. The welding time of each weld point can be configured and stored according to process requirements, significantly reducing labor while greatly improving productivity. The system ensures continuous and high-speed welding. A 9–12 meter rebar cage frame can generally be completed within 20 minutes, and spiral winding and welding can be finished within approximately 25 minutes.
The workstation delivers excellent welding quality with no false or incomplete welds. Welding time and position are precisely controlled, ensuring reliable quality while reducing welding material consumption. The system supports multiple preset cage specifications, allowing operators to directly call stored parameters and perform one-touch operation via the touchscreen interface. The streamlined workflow is simple and intuitive, with a high level of automation. Product quality fully complies with industry standards.
In traditional manual production, project supervisors often inspect the fabrication site daily. With the Rebar Cage Welding Workstation YGTZ2500-12, all production data is automatically monitored, and the welding process is recorded and inspected in real time. The system promptly reports monitoring information, ensuring stable and reliable processing quality.
