Abstract

A major challenge in maintaining the readiness of the U.S. Navy is the rapid acquisition of spare or refurbished components for its fleet. This paper describes the preliminary results of a current research program to develop processing tools and techniques for highly productive, rapid, low-volume, low-cost, efficient refurbishment of worn and/or corroded ship components for the U.S. Navy. The discussion includes the design of; a unique Robotic Laser Cell for cladding and hard facing using either a diode or Nd:YAG laser; investigation of techniques for High Power Direct Diode Laser cladding, development of Laser Power Measurement and Diagnostics Calorimetric system; and a Vision Image Control system for positioning of filler metal and a Laser Beam Height Control system.A major challenge in maintaining the readiness of the U.S. Navy is the rapid acquisition of spare or refurbished components for its fleet.
