Description
Automatic CNC Longotudinal Seam Welding Machine for Duct or Cylinder
I.Main welding processes
The straight seam welding machine can integrate welding processes including MIG/MAG, TIG, SAW, and Laser to meet the needs of different scenarios.
| Welding process | Principles and characteristics | Applicable scenarios |
| MIG/MAG | Gas metal arc welding (MAG) is characterized by high efficiency, low cost, and minimal deformation. MAG welding is commonly used for ferrous metals such as carbon steel and alloy steel. | Welding of thin plates in automobile manufacturing, steel structure, thin-walled pressure vessels, etc. |
| TIG | Stable electric arc, high weld quality, no spatter | Precision welding of stainless steel, aluminum and aluminum alloys, or welding of thin plates (0.5mm and above). |
| SAW | Using granular flux to cover the electric arc results in high thermal efficiency, deep penetration, and aesthetically pleasing weld beads. | Welding of medium and heavy plates, such as pressure vessels and straight seam steel pipes. |
| Laser | High energy density, small heat-affected zone, fast welding speed, and minimal deformation. | Precision manufacturing and deep penetration welding of thick plates, such as shipbuilding and power generation equipment (single-pass welding of thick plates). |

III.Main structure
- Cantilever Welding Main Unit: The main structure of the equipment adopts a cantilever beam design. The cantilever beam is typically subjected to post-weld annealing to relieve stress and ensure long-term stability and prevent deformation during welding torch movement.
- Key-Type Clamping Mechanism: This is one of the core features of a straight seam welding machine. Composed of multiple independent cylinders arranged closely along both sides of the weld seam, it provides uniform and powerful clamping force across the entire welding length, effectively suppressing welding thermal deformation.
- Welding Mandrel (Backing): A copper fixture located on the back of the weld seam. It not only provides support but also features forming grooves and back gas protection channels to achieve single-sided welding with double-sided forming and protect the back weld seam from oxidation.
- Walking Drive System: Typically driven by a servo motor, combined with high-precision gear racks and linear guides, ensuring smooth torch movement and positioning accuracy (movement accuracy up to 0.2mm).
- Control System: Employs a PLC and touchscreen human-machine interface for fully digital centralized control. It can preset, store, and recall welding parameters, and has functions such as one-click operation and fault diagnosis.
