Multifunction laser welding head has been developed. The head is able to perform not only underwater laser welding as repair, but also laser peening as preventi ve maintenance and laser ultrasonic testing as inspection. Laser transmission test with multifunction laser welding head and optical fiber was carried out. The result showed that laser power needed for welding was transmitted without any damage to them. Under water laser welding onto EDM slits with this welding head w as carried out. EDM slits were...

Recently, stress corrosion cracking (SCC) has been observed at aged components of nuclear power plants under water environment and high exposure of radiation. Toshiba has been developing both an underwater laser welding directly onto surface of the aged components and underwater laser p atch welding as repair techniques. This paper reports underwater laser patch welding technique....
