Laser Welded Fin Tube
Laser welded finned tubes are heat exchange tubes where fins are securely bonded to the base tube using laser welding technology. Both the fins and base tube can be made from various materials such as stainless steel, titanium, copper, carbon steel, and others to meet diverse application requirements. This design not only increases heat transfer surface area but also enhances heat exchange efficiency, making laser welded finned tubes a preferred choice for heat transfer components in numerous industrial fields.

Laser Welded Fin Tube Description
Laser welded finned tube, also known as stainless steel laser welded finned tube, is an industrial heat exchange component manufactured using laser welding technology. It is primarily used in domestic wall-hung boilers and industrial boilers. Its materials include stainless steel, titanium, copper, carbon steel, etc., with base tube thickness ranging from 0.8-1.5 mm and fin thickness from 0.3-1 mm, offering material cost savings compared to high-frequency welded finned tubes.
The product achieves welding through fiber laser technology, with a penetration rate of up to 100%, effectively preventing gap corrosion and extending service life. Its small heat-affected zone enables processing of small-diameter finned tubes (10-80 mm in tube diameter) and supports combination welding of different materials as well as secondary processing (such as coiling and bending).
Laser welded finned tubes are the most technologically advanced products with irreplaceable advantages:
Material cost savings: The base tube thickness can range from 0.8-1.5 mm, and fin thickness from 0.3-1 mm, significantly reducing material costs compared to other processes.
High welding penetration: achieves 100% penetration, preventing gap corrosion, extending service life, and reducing thermal resistance.
Material flexibility: breaks through material limitations, allowing for processing of different material combinations.
Ease of secondary processing: can be directly coiled or bent without additional treatment.
Minimal heat-affected zone (HAZ): with small metallurgical changes, enabling the production of small-diameter finned tubes.
