The Annular Laser Deposition Head for External Cylindrical Cladding combines a transmissive optical system with a precision annular powder-feeding design for efficient external cylindrical laser cladding. The powder stream converges accurately with the laser beam at the processing point, supporting stable deposition on the external surfaces of cylindrical and complex-shaped components.
With smooth powder delivery and powder utilization exceeding 90%, the head helps reduce alloy waste while producing smooth, low-distortion cladding layers with excellent surface flatness. Its annular powder-feeding architecture is well suited to robotic integration and automated powder-fed directed energy deposition (DED), supporting consistent processing of complex geometries.
Depending on the deposited material and process parameters, coating hardness can be tailored across a wide range, with validated applications covering approximately 15–70 HRC, including carbide-reinforced wear-resistant layers. Designed for surface enhancement, wear protection, localized repair, and remanufacturing, it provides an efficient laser cladding head for external cylindrical surface repair under demanding industrial service conditions.

Q1: What is the powder utilization rate of this annular laser deposition head, and what hardness range can the cladding layer achieve?
A1: This annular deposition head achieves a powder utilization rate exceeding 90% thanks to its precision annular powder distribution and smooth
powder delivery design. Depending on the deposited material and process parameters, coating hardness can be tailored across a wide range,
with validated applications covering approximately 15–70 HRC,. making it suitable for
applications that require either enhanced wear protection or improved machinability after cladding.
Q2: Can this external cylindrical cladding head be integrated with robotic systems for cladding on non-cylindrical or complex-shaped components?
A2: Yes. The system is specifically designed for robotic automation and is compatible with complex-shaped component cladding. While optimized
for external cylindrical surfaces (such as hydraulic legs, mill rolls, and drive shafts), it can also perform targeted cladding on flat or irregular
workpiece surfaces, offering high flexibility for industrial repair and surface enhancement applications.
