| Abstract |
Laser repairing has emerged as an appealing alternative to traditional techniques for repairing cracks in nuclear reactor piping. In this paper, laser repairing of pipe specimens have been
attempted with varying postulated crack depths. Various repairing parameters were selected to repair
prefabricated grooves and repairing effectiveness was evaluated through metallographic observations
and indentation tests. Big differences in microstructures and hardness profiles were observed in repair
zones with different crack depths. Furthermore, laser-beam power and nozzle moving speed showed
obvious impact on the repair quality for a given crack depth. |
