The Coaxial LMD Head for External Cylrical Cladding features a transmissive optical system with a four-way precision coaxial powder feeding design, enabling uniform and highly efficient laser metal deposition by accurately converging powder streams at the center of the laser spot. The head is fully compatible with robotic systems for complex-shaped surfaces and vertical cladding applications, delivering significantly better vertical deposition performance than conventional annular powder feeding systems.With powder utilization rates exceeding 90%, the system produces cladding layers with minimal distortion and excellent surface flatness. It supports a wide range of materials, including high-hardness alloys and metal matrix carbide coatings. The unique four-way coaxial configuration improves deposition consistency, processing precision, and powder delivery efficiency, making it an ideal solution for demanding surface enhancement, wear protection, and complex component repair application
