Xinwei CNC fiber laser welding machine is designed for automatic longitudinal seam welding of stainless steel and carbon steel tubes. It integrates precision positioning, rotary fixture and fiber laser technology to achieve stable welding quality for mass production.
✓ CE Certified Fiber Laser Welding System
✓ Designed For Stainless Steel And Carbon Steel Tubes
✓ Automatic CNC Precision Welding Process
✓ Factory Direct Manufacturer With Engineering Support
✗ Traditional TIG/MIG welding is slow for continuous longitudinal seam production
✗ Manual arc welding produces inconsistent seam quality across production batches
✗ Post-weld grinding and finishing adds significant labor and time costs
✗ Heat distortion from conventional welding affects tube dimensional accuracy
The CNC-controlled rotary fixture ensures accurate tube positioning throughout the welding cycle. Precise alignment of the longitudinal seam before welding guarantees consistent weld quality for every tube section.
Fiber laser provides concentrated heat input with minimal thermal distortion. Compared to traditional arc welding, laser welding produces narrower heat-affected zones, cleaner weld appearance and significantly higher welding speeds for thin to medium wall tubes.
The automated longitudinal seam welding process runs continuously without manual intervention once set up. This eliminates operator fatigue, improves production consistency and allows one operator to manage multiple machines.
Suitable for welding stainless steel, carbon steel and galvanized steel tubes. Welding parameters can be adjusted for different material grades and wall thicknesses, making the machine versatile for diverse tube manufacturing applications.
Tube manufacturers face increasing demands for higher production speed, better weld quality and lower post-processing costs. Fiber laser welding offers significant advantages over conventional arc welding methods for longitudinal tube seam applications. The concentrated laser beam produces deep penetration with minimal heat input, resulting in stronger welds with less thermal distortion. Unlike TIG or MIG welding, laser welding requires no filler material and produces virtually no spatter, eliminating the need for post-weld grinding in many applications.
| Step | Process Description |
|---|---|
| 1 | Tube loading — workpiece secured in the CNC rotary positioning fixture |
| 2 | CNC alignment — longitudinal seam precisely positioned under laser head |
| 3 | Fiber laser welding — continuous seam welding with controlled parameters |
| 4 | Finished tube — smooth longitudinal weld with minimal post-processing required |
Used for longitudinal seam welding of stainless steel pipes for fluid transport, structural and decorative applications. The laser welding process produces clean, corrosion-resistant weld seams suitable for food-grade and pharmaceutical tubing.
Efficiently welds carbon steel and stainless steel exhaust pipes. The high-speed continuous welding capability matches automotive production line throughput requirements.
Suitable for welding thin-wall stainless steel tubes used in heat exchangers where low thermal distortion and consistent weld quality are critical performance requirements.
