mainstream 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). |

Specialized aircraft highlights: Designed specifically for straight seam welding.
Straight seam welding is a common process in industries such as pressure vessels, pipelines, steel structures, and hardware products. Our company's specialized straight seam welding machine is a dedicated automated device designed for longitudinal seam welding of cylinders and plates. The equipment employs a high-rigidity gantry structure or a precision cantilever structure, equipped with a high-precision linear guide and servo control system to ensure stable welding torch movement, thereby achieving a high-quality welding effect with aesthetically pleasing weld formation and uniform penetration.
We will develop professional welding solutions based on the customer's welding requirements.
The welding effect is shown in the image on the right.
