The Square Beam LMD Head for External Cylindrical Cladding features a reflective off-axis powder feeding design with a flat-top square beam, ensuring uniform energy distribution and minimal overlap defects for smooth, high-quality cladding layers. It supports both annular center powder feeding and composite deposition, delivering smooth powder flow with utilization rates ≥90%. Compatible with complex-shaped components and high-hardness carbides, this versatile head can also be used for precise laser hardening, providing a multi-functional solution for industrial surface enhancement and repair.

Ideal for surface strengthening and cladding repair of cylindrical, tubular, and flat components across various industries:
Mining & hydraulic support – External surface reinforcement of cylinder barrels and hydraulic legs in coal mining roof supports.
Steel & metal rolling – Wear-resistant cladding for mill rolls, backup rolls, work rolls, and other frequently replaced parts.
Power transmission systems – Surface performance improvement for crankshafts, drive shafts, main shafts, and other rotating components.
Pipeline & energy sectors – External wall protection for pipes used in oil, gas, chemical, and power generation facilities.
Hydraulic systems – Uniform cladding on plungers, sleeves, and tubular parts to ensure sealing reliability.
Flat or partial surfaces – Targeted cladding on localized flat areas or irregular workpiece surfaces.
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
