Laser welded finned tube is a finned tube product with relatively mature and stable process, which has good advantages:
1. The thickness of base tube can be 0.8-1.mm, and the thickness of fin can be 0.3-1.mm, saving material cost.
2. High penetration rate can prevent gap corrosion, prolong service life and reduce heat transfer resistance.
3. Different materials can be used for processing.
4. It is easy for secondary processing, and can directly coil and bend pipes.
5. Small welding heat affected zone and small metallographic change make it possible to process small diameter finned tubes.
