Product Description


Model: HM1200/12000


Designed for highmast pole, monopole, 5G communication pole


Diameter range:300~1200mm, Thickness:5~14mm, Length:12000mm

Standard single arc single wire submerged arc welding machine

optional: double arc double wire welding machine(for big thickness)

Scope of application: suitable for large length medium size pole longitudinal automatic closing welding, like 5G pole, monopole, highmast pole


CNC POLE SHUT-WELDING MACHINE , it is suitable for one shell or two shell type polygonal and circle taper pole(Conical pole). it is automatic welding line, the gantry type structure is fixed and with welding system, V-shaped fully pole length dolly(worktable) with servo motor for speed adjustable moving , The hydraulic cylinder push the clamping wheel to close the pole and do welding at same time.

For two seam pole, when first seam welding finished, the bottom roller will rise and rotate the pole to another seam position to start second seam welding.



Proprietary features:

  1. CNC automatic adjustment, CNC system, with the change of pole diameter, automatically adjust the pressure, automatically adjust the presser foot position, automatically match the feeding speed and position, keep the welding seam always in the closed state, to ensure the smooth welding.
  1. Special CNC control system makes the left and right side of the foot synchronization performance is very good
  2. On the basis of the qualification of the previous process, after welding, there is no torsion of the pole weld, and there is no need for personnel to pry and twist the rod at the back of the machine to center the weld.
  3. .The pole is on the V-shaped worktable, and its motion is servo controlled to ensure the stability of head and tail welding. Welding from head to tail greatly reduces the length of the tail that is not welded.
  4. The number of clamping roller is 3 sets, the advantage is reduce the roller pressure to the pole surface , and reduce the scratch on the surface . It is suitable for the production of octagonal pole, polygonal pole and conical pole. It can be equal diameter or conical.
  5. The V-shaped worktable(dolly) with motorized fast returning back function, and it reduces the labor intensity of operators.
  6. Submerged arc welding function
  7. With pole back guiding device,it can be adjusted adaptively. In practical operation, the position of welding seam is seldom adjusted, which reduces the labor intensity of operators.
  8. Through the camera installed on the machine head, the welding seam is reflected on the screen of main control panel, making the tracking of the welding seam simple and easy, and reducing the labor intensity of the operator for monitoring of the welding..
  9. The self-developed oil pressure and CNC system, making the welded pole round and deformation small.
  10. For two seam pole, when first seam welding finished, the bottom roller will rise and rotate the pole to another seam position to start second seam welding
  11. loading and unloading in the front position
  12. The inner copper blocks, which greatly improves the penetration rate, which can reach more than 85%. Copper block contains cooling water
  13. Operator: 1 person.
  14. Optional items: for plate thickness greater than 12mm, adopt double arc and double wire (or double electric and three wire) submerged arc welding, DC + AC, DC welding adopts high current and low voltage, DC arc obtains large penetration, AC adopts relatively small current and high arc voltage, increases fusion width, and obtains beautiful weld formation. Double the welding speed, improve the weld performance and reduce the power consumption.
  15. Optional item: networked production data system

Function 1: it can provide production data to production management personnel: power on time, welding time, non welding time, production quantity, etc

Function 2: timely update the software to obtain the best and latest software and experience data, which can assist customers in remote fault diagnosis and remote parameter adjustment. It is convenient for customers to quickly resume production.
