The core concept of laser cladding lies in “additive repair” and “performance enhancement.” By adding cladding materials onto the substrate surface, the technology is primarily used to restore high-value components damaged by wear or corrosion, such as rolling mills, rotors, and turbine blades. It is also widely applied to pre-coat vulnerable areas of new components with wear-resistant and corrosion-resistant alloy layers, including valve sealing surfaces and drilling rods.
