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 reducing 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.
