The Flat-Top Beam Laser Cladding Head for Internal Cladding features a reflective off-axis design that generates a flat-top square beam with highly uniform energy distribution. This beam profile significantly reduces the risk of porosity, cracking, and other defects at overlapping tracks, ensuring a stable and reliable cladding process.
The system supports both annular central powder feeding for laser cladding and off-axis wire feeding for wire-based deposition, providing excellent process flexibility. By integrating an optional laser hardening module, the head can perform surface laser hardening with a hardening beam width of up to 20 mm, enabling cladding and hardening operations within a single system.
Designed for internal diameters of 200 mm and above, this processing head is ideal for internal bore cladding, surface strengthening, wear protection, and integrated cladding-hardening applications in demanding industrial environments.

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.
