HM2500/14000 heavy-duty CNC pole shut welding machine is specially optimized for large-caliber thick-walled tapered steel poles. It realizes fully automatic longitudinal seam closing and submerged arc welding for 14m ultra-long light poles and communication poles.
This equipment supports 1-piece, 2-piece and 3-piece assembled pole structures, covering round tapered poles, octagonal poles and multi-sided polygonal poles. Adopting fixed gantry welding system plus servo synchronous moving V-shaped trolley, the machine completes hydraulic seam closing and continuous welding synchronously with high stability.
For double-seam poles, the system supports automatic lifting and pole rotation, realizing secondary seam welding without manual repositioning. It greatly improves continuous production efficiency for large-diameter pole manufacturing plants.

| Question | Answer |
|---|---|
| What is the maximum diameter pole this heavy-duty welder can handle? | HM2500 model supports large diameter from 400mm up to 2500mm, specially designed for super large tapered power poles and high mast poles. |
| What is the advantage of 2200mm super large pressing stroke? | The upgraded long stroke ensures sufficient closing displacement for 2000-2500mm big poles, avoiding insufficient seam closing and welding defects during large-caliber pole production. |
| Can this machine weld thick plates over 20mm? | The machine clamping force supports 25mm thickness. For high-standard penetration requirements above 20mm, secondary submerged arc surfacing welding is recommended to guarantee perfect weld quality. |
