Copper High Frequency Welded Fin Tube

High Frequency Finned Tube is processed by laser welding machine. High frequency finned tube use 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. High frequency welding machine is the most advanced 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 high frequency welded 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.

Advantages of High Frequency Welded Fin Tube

1. The high frequency welded Fin Tube (fin tube) fin machine has a high degree of automation, and the welding of the fin to the tube and the winding of the tube are synchronized

2. 100% welding rate, laser welding finned tube(Welded Aluminum Pipe) and fins are strong, the welding strength exceeds 600MPa.

3. The precision of laser welding tube(Electric Resistance Welded Pipe) finishing machine is up to 0.05mm

4. 0 contact resistance, achieve high efficiency of heat transfer of spiral finned tube by laser welding.

5. Save production costs. The laser welding finned tube has a smaller fin spacing, less than 2.5mm. Compared with the high frequency welded spiral finned tube(Spiral Welded Pipes), the heat transfer area is increased by about 50%, which makes the material cost Reduced, volume reduced Heat Exchanger.

6. The advantages over conventional MAG / HF welding are of decisive importance. The complete connection between the fin and the base tube brings excellent heat transfer, and the thermal performance of the fin tube is increased by 2.5 times. Continuous welding prevents the notch effect, thereby avoiding the formation of v-corrosion and cracks under the condition that the finned tube may swing. The heating of base metals during welding is low and the travel speed is up to 20m / min. Minimize the heat affected zone in the base tube. Therefore, it does not include the complete melting of the tube and the related metallurgical transformation of the parent metal.
