Abstract
The U.S. Navy has sponsored laser welding and cladding research at the Applied Research Laboratory - The Pennsylvania State University (ARL Penn State) to provide cost effective solutions for fabrication, repair, and refurbishment of components. Laser beam welding has been accomplished on many different alloys, ferrous and nonferrous, and thick (i.e. > 1") and thin i.e., approximates to 0.008") gauge materials. Carbon dioxide (CO2) and Neodymium Yttrium Aluminum Garnet (Nd:YAG) systems have been used for process development. Beam delivery systems have incorporated transmissive, reflective and fiber optics. Laser beam cladding (LBC) has been used to modify materials surface characteristics in terms of wear resistance and corrosion resistance. In addition, LBC can be used to "build-up" areas where mechanically-induced damage has occurred. Both LBW and LBC process development for Naval applications will be reviewed. LBC for improved wear resistance will be discussed. And, finally, LBW methods used to fabricate lightweight structures currently in use on the USS Mt. Whitney will also be presented.
