New innovation: Laser spiral welded fin tubes and tube finning machine:

Laser welded fin tubes is our new development in fin tubes research, which is able to completely automaticly, mechanically laser weld the fins to tubes with advanced welding quality, comparing to traditional high frequency welded fin tubes.

The advantages of Laser welded fin tubes:

1. Laser welded tube 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 resistanceHigh coefficiency of heat transfer for spiral fin tubes by laser welding.
5. Save production cost. Laser welded fin tubes has more small fin pitch, less than 2.5mm, its heat transfer area increase around 50% comparing to high frequency welded fin tubes, which make material costs decrease largely as well as volume of heat exchanger.
