Pipe Pile Rebar Cage Welding Machine Price
High-Efficiency Automated Cage Production: Fully automatic CNC control enables fast, continuous welding with 3–4× manual productivity while reducing labor and material consumption.
Stable Resistance Welding Quality: DC resistance welding delivers uniform, high-strength joints with ≤5% strength loss, ensuring reliable cage performance and minimal spatter.
Flexible Multi-Specification Capability: Compatible with square and round pipe piles and multiple bar sizes, supporting precise preset pitch and length for diverse production needs.
Machine Overview
The Pipe Pile Rebar Cage Welding Machine is a fully automated professional system designed for manufacturing high-strength concrete pipe pile rebar cages. The equipment delivers minimal welding strength loss, fast forming speed, a rational mechanical structure, and easy maintenance. Combined with modern variable-frequency control and a human-machine interface, the system ensures stable and reliable long-term high-speed operation while producing high-quality reinforcement cages.
Power System Options
Medium-frequency version: Uses medium-frequency inverter technology to reduce energy consumption by over 30%. It provides more stable welding current and uniform weld quality, ideal for high-precision, high-volume pipe pile production.
Power-frequency version: Uses a traditional industrial transformer with mature technology, low failure rate, easy maintenance, and strong cost performance — suitable for medium and small production capacities.
Key Advantages
Compatible with square and round pipe piles — one machine processes both cage types without additional equipment investment.
Resistance welding core technology with DC heating ensures fast thermal response, strong weld joints without spatter, and strength loss ≤5%, outperforming conventional welding.
Fully automatic CNC control with PLC and variable-frequency speed regulation enables precise preset pitch and cage length with minimal error.
High efficiency with reduced labor and material consumption — welding line speed up to 3000 mm/min, 3–4× manual efficiency; no overlap needed for stirrups, saving about 1.5% material; a small crew can complete operation.
Stable, durable, and user-friendly — intelligent fault alerts, touchscreen interface, quick learning curve, and support for 24-hour continuous production.
Supports multiple rebar specifications — capable of processing various longitudinal and ring bar diameters to meet full pipe pile production requirements.
Typical Applications
Pipe pile manufacturers — standardized cage production for precast square and round piles.
Infrastructure precast plants — bridge, railway, highway, port, and marine foundation piles.
Building construction bases — residential, industrial, and commercial foundation piles.
Municipal engineering projects — roadworks, underground pipelines, wastewater facilities.
Professional piling contractors — on-site cage prefabrication near construction areas.
Hydraulic engineering — reservoirs, embankments, and river regulation projects.
This machine is an essential solution for standardized and high-efficiency pipe pile reinforcement cage production in infrastructure prefabrication.
