Automatic Pipe Flange & Elbow Pipe To Flange Welding Machine

 

Pipe-to-Pipe Welding
Automated circumferential welding for pipe sections and pipeline fabrication.
Pipe-to-Flange Welding
Designed for consistent circumferential welding between pipes and flanges.Customized multi-station pipe flange welding machine
Elbow Pipe-to-Pipe Welding
Suitable for automated welding of elbow -pipe-to-flange connections.
Other Pipe Fittings
The system can also be used for welding applications involving tees and other pipe fittings, depending on workpiece dimensions and machine configuration.

 

 

 

• Automated Circumferential Welding

The workpiece is held and rotated by the welding positioner while the welding torch remains at the controlled welding location, providing a practical solution for automated circumferential welding.

• Reduced Workpiece Handling

Multiple weld joints can be processed without frequently moving the complete pipe or fitting assembly, which is one of the principal advantages described for this machine.

• PLC Touchscreen Control

The system is equipped with a PLC touchscreen control box for centralized operation of the welding equipment.

• Adjustable Welding Torch

The torch position can be adjusted according to workpiece dimensions, including vertical and front/rear positioning.

• Customised welding solution

We customize professional welding solutions based on the welding requirements of the workpiece, such as pipe bends and flanges, pipe-to-pipe connections, and pipe-to-flange connections or splices, etc.

The system is suitable for applications that require gas-shielded arc welding and supports the following processes:

• Argon Arc Welding (TIG/GTAW)
• CO₂ Shielded Welding - The system can be set up for CO₂-shielded welding in accordance with production requirements.
• Submerged Arc Welding - This process can also be configured for suitable pipe and fabrication applications.

The manufacturer of the welding power source states that the power source can be customized to match the required welding method.

 

 

• Stable Workpiece Rotation

Controlled rotation of the positioner helps ensure steady movement during circumferential welding.

• Less Manual Repositioning

The cantilever design enables the welding system to travel from one weld location to another, instead of repeatedly relocating long pipe assemblies.

• Adjustable Torch Position

Multi-directional adjustment enables the welding torch to suit various workpiece dimensions and joint locations.

• Flexible Welding Process Setup

The system can be set up for different welding processes and welding power sources.

• Integrated Workholding

The chuck, positioner and welding equipment operate together as one integrated fabrication system.
