Bored Pile Rebar Cage Welding Machine

Bored Pile Rebar Cage Welding Machine

The Bored Pile Rebar Cage Welding Machine is a fully automatic professional system designed for manufacturing high-strength concrete pipe pile reinforcement cages. The machine features minimal welding strength loss, fast forming speed, a well-structured design, and easy maintenance.

With modern variable frequency control and an advanced human-machine interface (HMI), the system ensures stable, reliable operation and consistent high-quality reinforcement cage production even under long-term, high-speed running conditions.

Versions Available

• Medium Frequency (MF) Version
  Adopts medium-frequency inverter technology, saving over 30% energy. Provides more stable welding current and more uniform weld points. Ideal for high-precision and large-batch pipe pile production.

• Power Frequency (PF) Version
  Uses a traditional power-frequency transformer with mature technology, low failure rate, and convenient maintenance. Cost-effective and suitable for small to medium production capacity and standard pipe pile processing needs.

Key Advantages

1. Universal for Square & Round Piles
   One machine processes both square and round pipe pile reinforcement cages, eliminating the need for additional equipment and reducing investment costs.

2. Core Resistance Welding Technology
   DC power supply ensures rapid heating and high thermal efficiency. Weld joints are firm, spatter-free, with strength loss ≤5%, far superior to traditional welding methods.

3. Fully Automatic CNC Control
   PLC + variable frequency speed control system with precise preset spiral pitch and cage length. Minimizes errors and eliminates the precision limitations of manual welding.

4. High Efficiency & Material Saving
   Welding line speed reaches 3000 mm/min, delivering 3–4 times the efficiency of manual work. Spiral bars require no overlapping, saving approximately 1.5% material. Only five workers are needed per shift.

5. Stable, Durable & Easy to Operate
   Intelligent fault alerts and touchscreen operation enable operators to get started within 30 minutes. Supports 24-hour continuous production for large-scale manufacturing.

6. Multi-Specification Compatibility
   Processes various diameters of longitudinal and spiral bars, meeting full-specification production requirements for pipe pile foundation projects.
