The Square Beam LMD Head for External Cylindrical Cladding combines a reflective optical system with precision off-axis powder feeding for high-efficiency powder-fed laser metal deposition (LMD). Engineered for external cylindrical laser cladding, its flat-top square beam provides highly uniform energy distribution across the processing area, helping reduce local overheating and overlap-related defects such as porosity, cracking, and excessive height variation. This supports stable deposition and smooth cladding layers with excellent surface flatness on cylindrical and complex-shaped components.
With powder utilization of 90% or higher, the head helps reduce alloy waste while supporting a broad range of feedstock materials, including high-hardness alloys and carbide-reinforced composite powders. It is suitable for wear-resistant coating deposition, surface enhancement, localized repair, dimensional restoration, and component remanufacturing.
The same head can also perform precision laser hardening, combining cladding and hardening capabilities in one flexible surface-processing solution. For OEMs, repair centers, and system integrators seeking a square beam laser cladding head for external cylindrical surface repair, it offers uniform flat-top energy distribution, efficient powder delivery, flexible material compatibility, and repeatable processing quality for demanding industrial applications.

Q1: Why choose a square beam LMD head over a traditional round beam for cylindrical cladding?
A1: The flat-top square beam provides uniform energy distribution across the entire cladding width, significantly reducing overlap defects and
improving surface smoothness compared to round beam systems. This results in higher-quality cladding layers with fewer post-processing
requirements — ideal for hydraulic legs, mill rolls, and drive shafts.
Q2: Can this square beam deposition head be used for applications other than cladding?
A2: Yes. In addition to laser metal deposition (LMD) with powder utilization rates ≥90%, this versatile head can also perform precise laser
hardening on component surfaces. This dual functionality makes it a cost-effective solution for both surface enhancement (wear-resistant
coatings) and surface hardening applications across mining, steel rolling, and power transmission industries
