The laser cladding process is essentially a welding process utilizing an infinitely controllable laser beam as its heat source.
This technology allows for complete metallurgical bonding with minimal HAZ (heat affected zone) and dilution, along with a reduction in other undesirable side effects such as oxidation and decarburization. Unlike thermal spray processes, laser cladding can be used to recover, or even enhance, the mechanical properties of a component or substrate. The ability to clad/weld very thin sections, edges, and complex geometries with an overlay that is metallurgically superior to the substrate makes the previously impossible, possible!
Laser cladding has many advantages:
1. Metallurgical bonding between deposition layer and substrate and the strength is not lower than 90% that of substrate.
2. Less than 10% dilution rate so that the properties of deposition layer is almost not be impact by the substrate.
3. About 0.1mm to be melt on substrate surface with about 0.2mm HAZ.
4. Compact microstructure, small grain, few defects of cavity, slag, crack etc.
5. Able to customize the cladding layer with different properties.
6. Easier for automation.
