Laser welded carbon steel finned tube adopts continuous laser welding machine to complete the welding of finned tube automatic winding device. The fins are welded very firmly. Fins and tubes are welded without missing welding.
Laser welded carbon steel finned tube adopts the laser welding process, which can weld the carbon steel tubes and carbon steel fins with thinner wall thickness and denser fin pitch. The thinner bare tubes and denser fins can improve the heat transfer efficiency.

Advantages of laser welded carbon steel helical fin tubes:
1. Laser welded carbon steel finned tube adopts continuous laser welding machine to complete the welding of finned tube automatic winding device. The fins are welded very firmly. Fins and tubes are welded without missing welding.
2. Laser welding of carbon steel finned tubes is to dissolve the base metal of fins and tubes to realize welding. The strength of the finned tube can reach more than 600MPa.
3. Laser welding carbon steel finned tube using automatic finned tube laser welding machine adopts servo closed-loop system, with high transmission precision and precise welding.
