3. What Is a High-Frequency Welding Finned Tube Machine

• High frequency welding finned tube machines create spiral fin tubes with high-frequency induction welding. The machine initially feeds both a metal tube and a steel fin strip. The system rotates the tube while pulling the strip through.
• After feeding, the welding tool heats up the contact area. As a result, the machine forms a continuous weld along the fin and tube junction. Therefore, the fin is strongly bonded to the tube.
• Since this method utilizes high-frequency power, the welding area experiences rapid and localized heating. Thus, the machine can maintain high production rates.

4. Reasons Why High Frequency Welding Is Better

• Metallurgically strong welds can be achieved through the use of high-frequency welding. Welding strength will also be consistent throughout the entire tube.
• The fins also cannot vibrate or distort due to the weld strength. Because of this, industries that need strong finned tubes typically specify welded fin tubes.
• Additionally, you can produce taller fin heights with this technology compared to other mechanical processes. This gives you more surface area for heat transfer on the tube.
• For these reasons and more, many heat exchanger manufacturers use the high-frequency welding finned tube machine.

5. Principle Of Operation

1. Operators begin by feeding smooth base tubes into the feeding system of the machine. Next, the system positions the steel fin strip onto the tube.
2. The tube will rotate as the fin strip is brought into contact with the surface. During this time, the high frequency induction coil is heating the contact area.
3. As a result, the strip will weld to the edge of the tube. Also, there are forming rollers that help press the strip onto the tube as it welds.
4. Once completed, the finished spiral fin tube will leave the production area to be inspected.
5. Since all of these steps occur one after the other continuously, production speeds can be high.

6.The Main Components of Machine

6.1 Tube feeding unit

Tube feeding unit accurately places the tubes. In addition, it allows tubes to rotate stably.

6.2 Fin strip feeding unit

Fin strip feeding unit feeds the fin strip continuously. As a result, spiral fins are formed uniformly on the tube.

6.3 High-frequency welding unit

High-frequency welding unit contains a welding generator. It generates high frequency current so that contact edge can be heated up quickly for welding.

6.4 Forming rollers

Forming rollers give shape to the spiral fins. Besides, they ensure uniform fin pitch on the tube.

6.5 Control system

Control system allows operators to adjust speed, pitch and welding power.

The above main components integrate into the reliable high frequency welding finned tube machine.

7.Technical Benefits

First of all, the machine can offer great welding strength. Besides, it can produce uniform spiral fins on the tube.

In addition, the machine is suitable for automatic production. As a result, factories can greatly improve the productivity.

Also, this welding process saves energy. So manufacturers can lower down the operating cost.

Benefits of this machine include:

• Uniform metallurgical weld
• Uniform spiral fin formation
• High productivity
• Adjustable fin pitch and height
• Uniform welding quality
• Long service life of equipment

Thanks to these benefits, high frequency welding finned tube machine is widely used in heat exchanger production.

8. Comparison with Similar Fin Tube Machines

• High-Frequency Welding VS Extruded Fin Tube Machine

Extruded type machines produces aluminum fins by mechanical means. On the other hand, welded type machines welds steel fins by utilizing welding technology. Hence, welded fins can sustain higher temperatures.

• High-Frequency Welding VS Low Fin Tube Machine

Low fin machines creates low fins on tube surfaces. Welded machines produces comparatively higher fins. Therefore, welded tubes offer more heat transfer surface area.

• High-Frequency Welding VS L-Foot Fin Tube Machine

L-foot machines rolls the fins mechanically. Welding machines bonds the fins permanently by using welding. Hence, welded fins offer better performance in severe industrial applications.
