Fully Automatic Bore Pile Cage Welding Machine

Compatible with both square and round piles – One machine covers the processing of two types of pipe pile rebar cages, eliminating the need for additional equipment and reducing overall production investment costs.

Core resistance welding technology – DC power supply enables rapid heating and high thermal efficiency. Weld joints are firm and spatter-free, with strength loss ≤5%, delivering far superior quality compared to traditional welding methods.

Fully automated CNC control – PLC system combined with variable frequency speed control allows precise presetting of pitch and length with minimal tolerance, eliminating the accuracy issues associated with manual welding.

High efficiency, labor and material saving – Welding line speed reaches up to 3000 mm/min, achieving 3–4 times the efficiency of manual work. No lap joint is required for stirrups, saving approximately 1.5% of materials. A team of just five workers can complete the entire shift operation.
