Advantages

  • Superior Bonding: Laser welding ensures continuous, clean joints with no filler metal.
  • High Heat Transfer Efficiency: Excellent fin-to-tube contact maximizes thermal conductivity.
  • Corrosion Resistant: Suitable for harsh environments including offshore and chemical plants.
  • Precision Manufacturing: Ideal for demanding industrial applications.
  • Longer Lifespan: Reduces maintenance and replacement costs.
  • Customizable: Fin pitch, height, and materials can be tailored to project needs.

Applications

  • Power Plants – waste heat recovery units, boilers
  • Petrochemical & Chemical Industry – process heaters, coolers
  • HVAC Systems – air heating and cooling coils
  • Marine & Offshore – corrosion-resistant applications
  • Refineries – condensers and air preheaters

Working Principle

The laser welded fin tube is made by using a high-energy-density, coherent, and collimated laser beam to join the fin strip and base tube.

Laser welding can produce narrow and deep welds with higher metallurgical bonding and less thermal distortion, ensuring excellent mechanical strength and high thermal conductivity of the fin tube. The welding seams are continuous and super clean, which is ideal for high-performance heat exchanger applications.
