Szczegółowy opis produktu
welding workpiece: steel/ metal pipe with big diameter welding length: 2-14 meters
welding diameter: 500-2500mm welding thickness: 6-28mm

automatic welding machine for large-size steel/iron pipe




This special welding machine is mainly used for straight submerged arc welding of large size steel electric poles, it is highly automatically, and powered by the USA brand Lincoln welding power supply



Technical Parameters:


Equipment main purpose and performance


Automatic closing and welding machine is used for automatic closing and welding for straight seam pipes.

It comprises main machine, welding power, mechanical welding seam center adjustment system and central control system. Its main machine has hydraulic closing mechanism, press rollers, machine frame, pipe conveying trolley and rail.


Suitable process range and welding process

  • Pipe material: mild steel, Q235,Q345,Q420
  •                        carbon steel, Q235,Q345,Q420
  • Pipe diameter range: Φ500-2500mm
  • Pipe max  thickness:6-28mm
  • Pipe length: 2-14m
  • Pipe welding method: MAG, the pipe will move, welding gun is fixed. We confirm with MAG welding, there is no welding droppings.



Automatic closing and welding machine consists of motorized closing seam main machine, welding system, pipe conveying system and control system

  1. floating mechanical closing seam main device

The main part of Straight seam pipe automatic closing and welding machine is Mechanical closing seam machine. It is composed of gantry type frame, upper press roller device, side press roller device, crossbeam, and bottom supporting trolley. Four sides press rollers will close the bended pipe, make the seam smallest, and control the seam axial misalignment, and press roller is driven by hydraulic system.


     2. Mechanical welding seam following system

Adopt guide wheel blocking in the welding seam, force the welding gun and seam are in the same line, avoid welding seam off-tracking during the welding process


     3. Welding design

Welding system is comprised of gas shield welding system, motorized plus shape carriage, automatic water-cooling welding gun and recycle water cooling system. This part will finish pre-welding for pipe.

  • Gas shield welding system composed of welding power, wire feeding mechanism, shield gas conveying device, the welding power is USA Lincoln DC 600
  • Motorized plus-shape carriage: adjust welding gun alignment position, stroke 50x200mm
  • Automatic water cooling welding gun: use Germany TBI brand, model 500A automatic spinning type water cooling welding gun
  • Recycle water cooling system: choose standard water cooling box,pipe conveying system

Inputting system is composed of feeding trolley, pipe positioning device and steel rail. It is used for pipe conveying. The welding method of this system is pipe moving, welding gun fixed way to weld.

Feeding trolley driving system adopts gear and rack meshes, to make sure the stable running.

Steel rail use 43 kilos heavy rail, to make sure the straightness

The trolley has two speed, during the welding, it runs slowly, during returning, it runs fast.

  1. Steel pipe closing system

The steel pipe closing system is the key part of this equipment. During the pipe bending process, the pipe will have some defect, which will bring difficulty to closing seam. We adopt three points adding pressure, two points supporting way to solve this problem.

Closing system includes left-right press rollers, up and bottom press rollers, up and bottom supporting carriage

The left-right press roller requires high-accuracy synchronization, and is driven by cylinder with hydraulic synchronization device.

Up and bottom press rollers will press and flat the seam, to avoid seam misalignment.

Up and bottom supporting carriage is fixed type, and mounted in trolley.

6 control system

Using PLC to realize program control, and pipe driving motor is inverter stepless speed regulation, constant torque output

The equipment has numbers of testing and safety protect device, and equipped with 1 set of main control cabinet and 1 control box.

In the control box, it sets big-screen human-computer interface, we can make digital setting for welding parameter and equipment function


Equipment characters


Our machine has advantage of modularity, mechanize, and automation

  • high production efficiency: This machine is to close and weld seam after bending pipe, closing and welding is done at the same time
  • The equipment has high stability: adopts good-synchronization driving system to make sure the high accuracy; adopts precise linear guide rail to support all movable parts, to make sure the stable running during the welding process; adopts inverter motor and gear track to drive trolley to convey pipe, to make sure welding speed is stable.
