LASER CLADDING



We have been developing laser- cladding services for a variety of applications in different industries, ranging from medical parts to gas turbine components. Due to its superior focusing ability, lasers allow power densities that are not typically possible with conventional thermal procedures. This enables us to process components with minimal thermal loading and distortion. Laser cladding is particularly suitable for applications demanding a high dimensional accuracy. Additional applications include materials that are difficult to weld using conventional methods, such as high temperature-resistant nickel-based alloys in gas turbines or tungsten-carbide-filled wear-protection coatings. Typical components include turbine blades, drilling equipment, and pump components.
