Product Description

Double Arc Multi-Wire Submerged Arc CNC Pole Shut Welding Machine For 14m Diameter 1.9m Steel Pole

Product Overview

HM1900/14000 CNC Pole Shut-Welding Machine is an automatic longitudinal seam submerged arc welder specifically designed for conical octagonal 5G communication poles and high mast poles.

Item	Details
Product Name	CNC Pole Shut-Welding Machine
Model	HM1900/14000
Application	5G communication pole, power monopole, high mast light pole
Processed Pole Shape	Round conical pole, octagonal & multi-sided polygonal pole (1/2/3 shell structure)
Welding Technology	Double arc multi-wire submerged arc welding
Max Pole Length	14000 mm
Customizable Options	Remote online diagnosis system, insulated & air-conditioned electrical cabinet, spare parts package

Product Introduction

HM1900/14000 CNC pole shut-welding machine is specially developed for longitudinal closing seam automatic welding of long tapered poles, including 5G communication poles, power monopoles and high mast poles. It is applicable for one-piece, two-piece or three-piece conical round and polygonal poles.

The equipment adopts gantry fixed structure matched with welding system, servo-driven adjustable-speed V-shaped trolley for pole transportation. Hydraulic clamping rollers close the pole seam while welding proceeds simultaneously. For two-segment two-seam poles, after finishing the first welding seam, lifting rollers jack up and rotate the pole automatically to position for secondary seam welding.

Core Advantages

Advantage Item	Detailed Description
Intelligent CNC Automatic Adjustment	The CNC system automatically adjusts clamping pressure, roller position and trolley speed following pole diameter change, continuously keeps seam closed during welding
Excellent Synchronous Hydraulic Control	Optimized hydraulic & control system guarantees high synchronization for left, right and middle clamping rollers
Low Pole Deformation After Welding	No torsion on finished welding seam. No manual prying and seam alignment required at machine outlet if upstream forming process meets specification
Stable Head-to-Tail Welding	Servo-controlled V-shaped trolley realizes continuous welding from pole head to tail, reduces unwelded tail segment length
Triple Roller Clamping Design	Three groups of pressing rollers disperse surface pressure, reduce indentation and scratches on pole surface; suitable for round, octagonal and tapered poles
Fast Automatic Trolley Return	Motorized quick return function for V-type trolley, reduce operator labor intensity
Adaptive Rear Seam Guide Device	Self-adjustable guiding structure, rarely manual calibration required during continuous production
Visual Weld Monitoring	Camera installed on welding head transmits seam image to main control screen for easy seam tracking and observation
Water-cooled Inner Copper Backing Block	Greatly improve welding penetration and guarantee consistent weld formation
Automatic Rotation for Double-Seam Poles	Built-in lifting roller mechanism to rotate two-seam pole automatically for secondary welding
Simple Operation	Only 1 operator required for whole production cycle
Optional Upgrade Configurations	Remote fault diagnosis & parameter adjustment network system; insulated air-condition electrical cabinet; spare parts package

Application Scope

5G tapered communication monopole longitudinal seam welding
Highway & power transmission steel monopole manufacturing
High mast lighting pole, octagonal multi-sided lamp pole production
Steel structure tapered tubular component closing seam welding

Frequently Asked Questions

Question	Standard Answer
What types of poles can HM1900/14000 welding machine process?	It is suitable for 14m long round tapered pole, octagonal and multi-sided polygonal poles (1/2/3 shell structure). Processing diameter range 400~1900mm, applicable thickness 5~20mm.
Does this machine support automatic welding for two-seam octagonal poles?	Yes. After completing the first welding seam, the lifting roller rack will jack up and rotate the pole automatically to realize the second seam welding without reloading.
Is extra surfacing welding needed for plates over 20mm thickness?	The machine clamping force supports material up to 25mm. But for workpieces requiring high penetration within 20~25mm, molten steel filling may be insufficient. We suggest adding submerged arc surfacing welding after primary welding.
