Characteristics and application of Laser Welded Finned Tubes
Laser Welded Finned Tube is a new, wear-resistant and efficient heat exchange material in the Finned Tube welding industry. It is an efficient and energy-saving heat exchange element with high heat exchange efficiency, large heat dissipation area, long service life, strong temperature adaptability, wide range and high pressure, which meets the national energy conservation and environmental protection emission standards. It is widely used in waste heat recovery, petrochemical industry, power station boilers, economizers, passenger cars, heating and cooling systems of industrial and civil buildings and other industries.
Base Tube Material: Steel, Aluminum, Copper, Titanium, etc.
Thermal Material: Copper, Aluminum
Wende tube length: unlimited
Product description: 100% welding between fins and tubes, no filler material. Laser welding is done in the seam.
Laser welded Finned Tubes in fins and tubes
100% welded, no filler material is used. There are no impurities on the weld seam, and laser welding can be carried out in a protective atmosphere. Different materials for fins and tubes. Simple bending and coiling of finned tubes. Due to the small heat-affected area and weld seam, the material does not deform, while the tubes and fins have only slight microstructural changes.
Laser welded finned tubes are widely used in chemical, power, air conditioning engineering, petrochemical engineering and refrigeration engineering, such as surface air coolers, air heaters, and fan coil units used in air conditioning engineering. The equipment is used in the cooling fan evaporator and the frost-free refrigerator evaporator used in the refrigeration project.
Spiral Welded Finned Tube is one of the most common types of finned tube. By spirally winding the fins on the base tube and welding at the bottom of the fins, the connection between the fins and the base tube is very close, which can prevent the fins from loosening due to thermal stress, oxidation, corrosion and other reasons, so they can be used at very high temperatures.

The laser welding finned tube is not only suitable for the flow of single-phase fluid in the process of use, but its equipment also has great value for the phase change heat. Most of the finned tube heat exchangers used for clean gas use The new high-efficiency fin surface structure achieves a significant heat transfer enhancement effect.
Compared with other processes, the laser welding finned tube greatly saves the material cost to a certain extent, and achieves a High Penetration Rate, which can effectively prevent the corrosion of its gaps during use, which will effectively prolong its The service life of the equipment reduces the thermal resistance of its heat transfer.
In terms of quality control of laser welded finned tubes, the equipment mainly uses its ccd monitoring system during the production process to monitor the welding area throughout the whole process, approve the first article, and use the metallographic analysis system to obtain the welding state and ensure product quality. Continue production after passing the test.
