What is Laser Metal Deposition and How Does It Work?

Laser Metal Deposition (LMD), also known as laser cladding, is an advanced additive manufacturing process in which a high-energy laser creates a controlled melt pool on the substrate while metal powder or wire is continuously fed into it. The operation takes place in a shielding gas environment to prevent oxidation and stabilize the molten zone. As the material melts and solidifies, it forms a strong metallurgical bond with the base surface, making LMD ideal for surface enhancement, dimensional restoration, and remanufacturing in aerospace, tooling, and high-value component repair.

How TEYU Industrial Chillers Support the Laser Metal Deposition Process
TEYU fiber laser chillers provide precise and reliable thermal management to safeguard build quality and maintain process stability throughout laser cladding. Featuring a dual-circuit cooling architecture, they independently cool two critical components:
1. Laser Source – Maintains stable output and beam quality by controlling resonator temperature, helping ensure uniform metallurgical bonding across each deposited layer.
2. Cladding Head – Cools the optics and powder-delivery nozzle to protect them from thermal load, prevent lens deformation, and maintain a consistent spot profile.

By delivering dedicated, stable cooling to both the laser generator and the cladding optics, TEYU industrial chillers support repeatable deposition quality, improve process consistency, and help extend the service life of LMD equipment.
