Small-diameter inner wall laser cladding head

The small-diameter inner wall laser cladding head system includes fiber interface, collimating lens, focusing lens/reflector, water cooling system, off-axis needle powder feeding system, gas protection system, etc. It achieves collimation and focusing of the transmitted laser, delivering metal powder 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 light spot, built-in water, gas, and powder channels, is high-temperature resistant, can withstand power up to 4000W, has high powder utilization, and high stability. It is an outstanding small-diameter inner wall laser cladding head on the market.

　　● Suitable for laser power ≤4000W, compatible with lasers in the wavelength range of 900nm-1080nm;

　　● Built-in water, gas, and powder channels along with a large water cooling channel to adapt to harsh environments during inner wall processing such as high temperature, smoke, large splashes, and light reflection, achieving stable inner wall processing;

　　● The end is a copper mirror direct output, protected by a light-transmitting nozzle that blocks splashes and continuous coaxial protective gas blowing on the lens, ensuring excellent cladding layer formation and extending the protective lens's service life;

● The copper mirror, light-transmitting nozzle, and powder feeding nozzle are all detachable, maximizing the service life of main structural components and effectively reducing usage costs;

● Capable of blind hole continuous processing without powder clogging or sticking; protective lens service life >600h;

　　● Reflective mirror coating achieves 99.25% laser utilization; copper mirror is directly water-cooled to reduce focal point offset;

　　● Uses high-quality optical components worldwide to ensure long-term processing stability; controllable dilution rate and heat-affected zone;

　　● Precision coaxial light and powder adjustment module enables precise adjustment of the light and powder positions for ultra-long inner wall cladding heads, ensuring cladding quality;

　　● High-quality off-axis needle powder feeding nozzle can stably deliver 38-150um metal powder, achieving 70% comprehensive powder utilization with appropriate laser processes.
