Alloy 600 Dissimilar Metal Welds Inspection Technique Phased Array UT Ultrasonic Testing
In the nuclear power plant, ultrasonic testing is performed as an in-service inspection of the reactor vessel (RV-ISI) according to JSME code. MHI is using the advanced UT machine (A-UT machine) system to RV-ISI under the high radiatio n condition. RV-ISI is one of the critical path in ISI schedule, so it is strongly required to reduce the inspection t ime of RV-ISI. In this report, the counter measure to reduce RV-ISI period by using the phased array UT is described....

Laser Nozzle Pipe Residual Stress Stress Corrosion Crack Weld
Improvement of residual stress is effective in a countermeasure for the stress corrosion cracks in pipe welds. An outer surface irradiated Laser Stress Improvement Process (L-SIP) will be introduced as a method to improve residual stress inside steel pipes. This method is to improve inne r surface residual stress from tensile stress to compressive by the temperature differences between inner and outer surface, that is generated b y the irradiation of laser beam around the welds of steel pipe. Recently this...
