Traditional spiral fin tubes are using high-frequency welding, resistance welding, and other technology to make the stainless steel fin attached to the steel pipe. In these kinds of welded spiral fin tubes, the welding process has its shortcomings that cannot be overcome.
While The laser welding spiral finned tube has a fully automatic welding process, saving manpower cost; secondly, laser welding fin solid and strong, high tensile strength test was qualified; laser welding more efficiency advantages, etc.
The laser welding machine is the most advanced laser welding equipment for the spiral finned tube. Laser welded spiral finned tube is using a laser welding machine processing. Because the welding process is fully automatic and mechanical, the scientific and technological content and quality of laser welded spiral finned tubes are better than the traditional cooling pipe.
Laser welding principle
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.
Stainless steel laser welded spiral fin tube:
1, a high degree of automation, automatic fins laser welding machine can realize one-time completion of welding, synchronous winding makes the fin foot and the pipe depth of the weld.
2 laser welding, high firmness, high binding force. Laser welding is metallurgical bonding, welding strength is more than 600MPa.
3, laser welding machine with high accuracy, welding an 8-meter-long fin tube with a precision of 0.05mm.
4. The heat transfer coefficient can be improved greatly by laser welding.
5, laser welding finned segment length is less than or equal to 2.5 mm, heat dissipation area than the high frequency welded pipe (distance is more than or equal to 4.5 mm) increased by nearly 50%, greatly reducing the material of the tube, also can decrease the change of the volume of the heat exchanger.
Advantages:
1. Thin, continuous weld seam
2. Small heat-affected zone
3. Short heating time
4. Only slight microstructural change in tube and fin
5. High utilization of heat for forming the seam
6. High welding speed
7. No impurity of the weld seam, as the Laser-welding is carried out under a protective atmosphere
Application:
1. Power Plants
2. Chemical Industry
3. Heat Recovery Plants
4. Heat Industry
