The Flat-Top Beam Laser Cladding Head for Internal Cladding features a reflective off-axis optical design optimized for precision internal diameter (ID) laser cladding. It generates a square flat-top beam with highly uniform energy distribution, helping reduce porosity, cracking, and uneven fusion in track-overlap zones while maintaining stable and repeatable cladding quality across large internal surfaces.
The head supports annular powder feeding directed to the beam center for powder-fed laser cladding and off-axis wire feeding for wire-fed laser deposition, providing flexibility for different feedstock materials and process requirements. An optional laser hardening module delivers a beam width of up to 20 mm, allowing cladding and surface hardening to be performed with one integrated head while reducing equipment changeover.
Designed for internal bores with diameters of 200 mm and above, this laser cladding head is suitable for internal surface repair, surface strengthening, wear protection, and combined cladding-and-hardening applications on large-bore industrial components. For OEMs, repair centers, and system integrators, it provides uniform energy distribution, flexible powder-or-wire processing, and consistent results under demanding operating conditions.

Q1: What is the advantage of a flat-top square beam over a Gaussian (round) beam for internal cladding?
A1: The flat-top square beam provides highly uniform energy distribution across the entire cladding width, significantly reducing the risk of
porosity, cracking, and other defects that commonly occur at overlapping tracks. This results in smoother, more consistent cladding layers
with less post-processing — especially critical for internal bore surfaces where rework is difficult and costly.
Q2: Can this internal cladding head also perform laser hardening on bore surfaces?
A2: Yes. By integrating an optional laser hardening module, this single system can perform both internal bore cladding and surface laser hardening
— with a hardening beam width of up to 20 mm. This dual functionality allows you to apply wear-resistant coatings (cladding) and selectively
harden base materials (hardening) without changing tooling, ideal for demanding internal surface protection applications.
