Laser welding of finned tubes adopts the laser welding process, which can weld the light tubes and fins with thinner wall thickness and denser fin pitch. The thinner light tubes and denser fins can improve the heat transfer efficiency. Good penetration rate and resistance to being pulled off are the basis of good service life.
Laser welding of finned tubes can realize welding between different metals, which can achieve good heat transfer efficiency for customers under different working conditions. Thin wall thickness is also one of the ways to save costs.
