Laser Welding Equipment For Finned Tubes
- Jan 11, 2019 -

Helical finned tube laser welding machine is a leading domestic laser welding equipment developed by Jiaozuo Shijia Energy-saving Company. It radiates high-intensity laser beam to metal surface. Through the interaction between laser and metal, metal absorption laser is converted into heat energy to make metal melt and cool and crystallize to form welding. It is mainly used for the welding of stainless steel finned tubes. The welding process is fully automated. The welding performance is stable and reliable. The laser welding spiral finned tubes have higher technology content, better quality and more competitive products than high frequency welding finned tubes.

The advantages of laser welding spiral fins of stainless steel are as follows:

1. Using optical fiber laser welding technology, the winding welding is completed synchronously, and the segment welding rate reaches 100%.

2. Laser welding is metallurgical bonding, and the strength of segment welding can reach more than 600 MPa.

3. Laser welding machine adopts servo drive system, which has high precision of chip distance processing.

4. Laser welded fin-and-tube spacing can be less than 2.5 mm, heat dissipation area is increased by nearly 50% than that of high frequency welded tube (fin spacing is more than 4.5 mm), and material consumption per unit area is less, which can greatly reduce the volume of heat exchanger.
