The External surface coaxial powder feeding cladding head is a high-efficiency external surface laser cladding head developed for wide-area coating, industrial component repair, and remanufacturing. Its reflective wide-beam optical design works with a precision powder-delivery system to achieve powder utilization of up to 98%, helping reduce alloy consumption and powder waste in powder-fed directed energy deposition (DED) and laser metal deposition (LMD) processes.
The head supports single-layer cladding thicknesses exceeding 4 mm and stable multi-layer deposition, producing a strong metallurgical bond between the deposited alloy and the substrate. The wide processing beam increases coverage per pass and helps reduce the number of scan tracks and overlap zones, supporting efficient and consistent deposition across large external surfaces.
Designed for wear-resistant surface enhancement, dimensional restoration, and thick protective coating buildup, it is well suited to demanding industrial repair applications. For OEMs, repair centers, and system integrators seeking a wide-beam laser cladding head for external surface repair and remanufacturing, this solution combines high powder efficiency, stable multi-layer capability, and material-efficient thick-layer deposition.
