Laser Welded Finned Tube Product Description:

Laser welded spiral Fin Tube is using a laser welding machine processing.

In traditional the spiral fin tubes are using high frequency welding, resistance welding and other technology to make the stainless steel fin attached on the steel pipe. Laser Welding Finned Tube, the welding process has its shortcomings that cannot be overcome.

While The laser welding spiral finned tube has full automatic welding process,save the manpower cost; secondly, laser welding fin solid and strong, high tensile strength test were qualified; laser welding more efficiency advantages etc.

The laser welding machine is the most advanced laser welding equipment for spiral finned tube . Because the welding process is fully automatic and mechanical, the scientific and technological content and quality of laser welded spiral finned tube are better than the traditional cooling pipe.

Laser Welding Fin Tube(Welded Spiral Pipe) Advantages:

1.thin, continuous weld seam

2.small heat-affected zone

3.only slight discoloration weld site

4.only slight microstructural change in tube and fin

5.high utilization of heat for forming the seam

6.increased safety because of the avoidance of crevice corrosion due to the high weld integrity between tube and fin impurity of the weld seam, as the Laser-welding is carried out under a protective atmosphere.
