Concrete Pipe Cage Welder

A concrete pipe cage welder produces the reinforcement cage that carries the pipe's ring and longitudinal loads. For reinforced concrete drainage pipe the cage must hold its roundness under the forming process and its spiral pitch must stay even along the barrel, because uneven pitch concentrates steel where the pipe does not need it. This welder covers Φ300–1200, Φ600–2000, Φ800–2400, Φ1500–3000 and Φ2000–4000 mm with 2–4 m cage lengths, welds under all-digital control, feeds bars by push rod, and keeps ring pitch adjustable across the full range.

The welding program runs the same on the first cage and on the five hundredth, because every cage is welded under all-digital control on components machined to fixed drawings. A second machine ordered years later welds to the same setting, which keeps your cage a controlled input to the pipe.
