Heat Exchanger Welded Fin Tube

Laser Welded Finned Tube Product Description:

Laser welding finned tube is processed by laser welding machine. Laser welding is a welding method that irradiates a high-intensity laser beam onto the metal surface. Through the interaction of the laser and the metal, the metal absorbs the laser light and converts it into heat, melting the metal to form a cooling crystal. Laser welding machine is the most advanced laser welding equipment for finned tubes. Because the welding process is fully automatic and mechanical, the scientific and technological content and quality of laser welding finned tubes are superior to traditional cooling tubes.

The laser welding finned tube has a fully automatic welding process, saving manpower costs; secondly, the laser welding fin is firm, strong, and the test with high tensile strength is qualified. Laser welding is more efficient.

Laser Welding Fin Tube Manufacturing Process:

Laser welding is a high intensity laser beam to the metal surface, through the interaction of laser and metal, metal absorption laser into heat to make the metal melt after the formation of cooling crystallization welding.

Laser Welding Fin Tube(Welded Spiral Pipe) Advantages:

1.Laser welded finned tubes (fin tubes) finning machine has high automatic, the welding of fin to tubes and winding on tubes are made synchronously

2.100% welding rate,  Laser welded fin tubes has strong soundness between fins and tubes, welding strength is over 600MPa.

3.Laser welded tube finning machine has high precision up to 0.05mm

4.0 contact resistance, high co-efficiency of heat transfer for spiral fin tubes by laser welding.

5.Save production cost. Laser welded finned tubes (fin tubes) has more small fin pitch, less than 2.5mm, its heat transfer area increase around 50% comparing to high frequency welded helical (spiral) finned tubes, which make material costs decrease largely as well as volume of Heat Exchanger.

Laser Welded Finned Tube(Stainless Steel Welded Pipes) Properties:

100% welding between fin and tube without using filler material.

No impurity of the weld seam, as the Laser-welding is carried out under a protective atmosphere

Different materials for fin and tube

Uncomplicated bending and coiling of the finned tube

No material deformation due to a small heat affected zone and thin weld seam, only slight microstructural change in tube and fin

Laser Welded Finned Tube(Stainless Steel Welded Pipe) Applications：

Right now the laser welded fin tube widely used in corrosive conditions, such as heat recovery in condensing boilers, and heat exchangers in Industries of Chemical, Petroleum, Petrochemical, Metallurgical, Power, Food and Maritime.
