Laser welded finned tube winding machine is a kind of production equipment that spirally wraps the steel strip around the base tube and simultaneously welds the steel strip and the base tube together by means of laser welding to form finned tubes. It features firm welding, uniform fin spacing and attractive appearance, and can realize welding with small fin spacing. During the laser welding process, the heat is relatively concentrated, which hasthe advantage of lower power consumption. 

I. Performance of Laser Welded Finned Tube Production Line:

1. Welding energy saving: Adopting high-performance laser welding withhighenergy efficiency conversion. Laser energy is concentrated at the joint betweenthe base tube and fins, enabling rapid melting and forming of weldingmaterials.

2. High welding efficiency: Equipped with new PLC programcontrol, allowingfree adjustment of welding speed and welding power, thus improvingproduction efficiency.

3. Convenient operation: Operated via a cantilever control box.

4. Welding angle: The newly designed laser welded finned tube productionlinefeatures a smaller welding angle, which prevents damage to the base tubewhen welding thin-walled tubes.

II. Technology and Manufacturing

1. Real-time imaging display

2. Stable machine tool bed: HGR45 solid guide rails are laid, making it more stable, smoother and more durable.

3. Bridge-type drag chain enables more flexible movement of circuits during operation.

4.  Three-wheel positioning of the base tube ensures more stable welding.

5. The use of Mitsubishi servo system combined with Mitsubishi PLC makes
the forming of spiral finned tubes more precise.
