As the most advanced product at present, laser welded finned tube has irreplaceable advantages.
1. The thickness of the base tube can be greater than 1mm, and the thickness of the fin can be between 0.4-1mm, which greatly saves the material cost compared with other processes.
2. High penetration rate can prevent gap corrosion, prolong service life and reduce heat transfer resistance.
3. Break through the material limit and use different materials for processing.
4. Easy for secondary processing, coil and elbow can be directly processed.
5. The welding heat affected zone is small and the metallographic change is small, which makes the processing of small diameter finned tube possible.
Laser welding finned tube welding is a very complex physical and chemical process, which involves the interaction between laser, material and plasma. However, in the process of laser welding, what affects and determines the welding forming conditions such as weld depth is the welding specification parameters such as laser power, welding speed, defocus and focus size. We have strict control over the above.
