Laser processing is well suited to implementation in high volume applications where a dedicated processing sell is used. The characteristics of laser processing (ease of automation, low heat input, fiber optic delivery) make it an attractive tool for repair processes. However, there are unique challenges to implementing laser systems both in existing work areas not specifically designed for laser operation and in the field when dealing with large parts that are not easily enclosed. On-going work at ARL Penn State is addressing these issues and developing systems for safe operation in both these work environments. In particular, on-going design
efforts are addressing laser safety issues in terms of enclosures, laser beam delivery/optics, shielding gas delivery, out of position processing, and the delivery of wire or powder cladding materials. This work presents the development of two portable, robotic laser clad repair systems designed to be brought to the component being repaired. The first is a deep-bore wire based laser cladding system for repairing valve components. The second is a high power reflective optics cladding system for repair of large shafting components. This paper presents some of the challenges and solutions associated with development of portable, robotic laser repair.
