Active Heating Infrared Imaging Nondestructive Evaluation SCC Sonic IR Thermography
Sonic-IR which is based on the thermographic detection of the temperature rise due to fric tional heating at the crack faces under ultrasonic excitation, has an advantage in the det ection of closed cracks. In this study, feasibility of the Sonic-IR technique for the dete ction of stress corrosion cracking is experimentally investigated by using plate specimens....

Array Probe Eddy Current Testing Nondestructive Testing Numerical Solution Steam Generator Stress Corosion Crack Transmit-Receive Type Probe
In 1998, NEL developed X-probe in cooperation with foreign firms. Recently NEL has developed the transmit-receive type array probe characterized with a significantly improved resolution for circumferential cracks. Th e advanced probe, called Smart Array Probe, has been developed based on the result of detailed numerical simulation. The doubled channels in the circumferential mode have greatly improved the circumferential resoluti on of Smart Array Probe. With all the circumferential mode channels on the sa...

Array Probe Eddy Current Testing JEAG4208 Nondestructive Testing Steam Generator Stress Corrosion Cracking Transmit-Receive Type Probe
In 1999, NEL developed the transmit-receive type ECT array probe for steam generator (SG) tubing, called “X-probe”, in cooperation with foreign firms. Recently NEL has developed the advanced ECT array probe, “Smart Array Probe”, characterized with a significantly improved resolution for circumferential cracks. The doubled channels in the circumferential mode have greatly improved the circumferential resolution of Smart Array Probe. With all the circumferential mode channels on the same circle, there i...

Eddy Current Testing Inspection PWR RV Head Penetration Ultrasonic Testing
This paper describes the result of demonstration test using WesDyne International's inspection system in terms of its sizing capability of crack from the inner diameter (ID) of PWR RV head penetrations, detectability of the crack e mbedded under repair welding, which was applied for isolation from the primary water environment, and the propagation of ultrasonic wave from the ID penetration to the inside of J-weld. The result of the laboratory tests have demon strated the sizing capabilities of both ultraso...

Sonic-IR which is based on the thermographic detection of the temperature rise due to frictional heating at the crack faces unde r ultrasonic excitation, has an advantage in the detection of closed cracks. Additionally, there is possibility to apply this te chnique to the inspection of complex geometry components because it is nearly non-contact technique. In this study, feasibility of the Sonic-IR technique for the detection of weld cracking is experimentally investigated by using small bore piping speci...

Piping Strain Gauge Strain Sensor Stress Vibration
Abstract In a small diameter piping, stresses are generated due to internal fluid or pump vibrations especially around the welding parts. Authors have successfully de veloped a pipe strain sensor which is able to measure such stresses. Unlike conventional methods using strain gages and adhesive bond, the sensor can measure the stra in without putting adhesive bond on the piping surface. However, the strain sensor can provide measurements with a level of accuracy equivalent to that of conventiona l method u...
