Inner Wall Reflective Coaxial Annular Laser Cladding Head

The inner wall reflective coaxial annular laser cladding head system includes fiber optic interface, collimating lens, focusing lens/integrating lens, water cooling system, annular powder feeding system, gas protection system, etc., achieving collimation and integrated focusing of the transmitted laser. Metal powder is delivered into the molten pool at the focal point to realize the melting and deposition of metal powder. The cladding head has a compact structure, homogenized spot, built-in water, gas, and powder channels, is high-temperature resistant, can withstand power up to 8000W, has high powder utilization, and high stability. It is a high-power inner wall laser cladding head with excellent market performance.
