Laser beam cladding: A flexible tool for local surface treatment and repair

The versatility of the laser beam cladding process as a means of localized surface treatment is highlighted in this article with an emphasis on applications in the field of repair and regeneration. A newly developed cladding technology using low power Nd:YAG lasers is also introduced. Small dimensions and minimal heat input allow high precision cladding. Short interaction times and good control of the process enable the generation of graded composite coatings. Application examples in the field of regeneration of components are given. An industrial case study presents the CO2 laser repair of large engine components.
