Laser welding finned tube is processed by laser welding machine. Laser welding is a welding method that irradiates a high-intensity laser beam onto the metal surface. Through the interaction of the laser and the metal, the metal absorbs the laser light and converts it into heat, melting the metal to form a cooling crystal. Laser welding machine is the most advanced laser welding equipment for finned tubes. Because the welding process is fully automatic and mechanical, the scientific and technological content and quality of laser welding finned tubes are superior to traditional cooling tubes.
The laser welding finned tube has a fully automatic welding process, saving manpower costs; secondly, the laser welding fin is firm, strong, and the test with high tensile strength is qualified. Laser welding is more efficient.
Advantages of laser welded finned tube
- The laser welding finned tube (finned tube) fin machine has a high degree of automation, and the welding of the fin to the tube and the winding of the tube are synchronized
- 100% welding rate, laser welding finned tube and fins are strong, the welding strength exceeds 600MPa.
- The precision of laser welding tube finishing machine is up to 0.05mm
- 0 contact resistance, achieve high efficiency of heat transfer of spiral finned tube by laser welding.
- Save production costs. The laser welding finned tube (finned tube) has a smaller fin spacing, less than 2.5mm. Compared with the high frequency welded spiral (spiral) finned tube, the heat transfer area is increased by about 50%, which makes the material cost Reduced, volume reduced heat exchanger.
The advantages over conventional MAG / HF welding are of decisive importance. The complete connection between the fin and the base tube brings excellent heat transfer, and the thermal performance of the fin tube is increased by 2.5 times. Continuous welding prevents the notch effect, thereby avoiding the formation of v-corrosion and cracks under the condition that the finned tube may swing. The heating of base metals during welding is low and the travel speed is up to 20m / min. Minimize the heat affected zone in the base tube.
Laser-Welded Copper Fin Tubes
The basic principle of laser welding copper finned tubes is to use a high-energy laser beam to locally heat the tube material, causing it to melt rapidly and form a weld joint. Laser welding technology uses a focused laser beam to precisely and rapidly heat the material surface, causing it to reach its melting point and melt in a very short time. This then forms a metallurgical bond with the base material, achieving the weld. During this process, the high energy density of the laser beam ensures the quality of the weld joint, resulting in a strong and durable weld.
Laser Welded Carbon Steel Finned Tube
Laser-welded carbon steel finned tubes primarily consist of a base tube and fins. The base tube, serving as the primary heat transfer channel, is typically made of high-quality carbon steel. This material not only offers excellent pressure resistance and toughness, but also maintains stable operation in high-temperature and high-pressure environments. The base tube’s diameter, wall thickness, and length are designed based on specific application scenarios and operating requirements to ensure optimal load-bearing capacity and heat exchange efficiency.
Laser Welded Stainless Steel Finned Tube
Laser-welded stainless steel finned tubes use 304 or 316L stainless steel as the base tube, with the fins joined via laser welding. Laser welding is characterized by high precision and efficiency, potentially resulting in improved thermal conductivity and structural strength. Compared to traditional methods, laser welding reduces the heat-affected zone, resulting in high-quality welds that are less likely to deform or crack. Stainless steel’s inherent corrosion and high-temperature resistance should also be considered, extending product life.
