Cast austenitic stainless steel Phased array UT Post processing Ultrasonic testing
Phased array ultrasonic testing (PAUT) has performed an important role for plant maintenances. However, many parts of cast austenitic stainless steels are difficult to be inspected by UT owing to their noises from large grains. We have been noticing that depending on the PAUT conditions, (e.g. incident angles and focal depths), the tendency of echoes from defects are different from that of grain noises. Thus we have developed new PAUT system which can analyze the tendency of echoes from comprehensive PA...

Linear scanning Low frequency array probe Phased array Ultrasonic testing
山本 智 Satoshi YAMAMOTO Non-Member (Times New Roman 10pt) should be about 150 words. Recently, an application target of the phased array ultrasonic testing (PAUT) has been extended. For the inspection of CASS, low frequency (less than 1 MHz) array probe is required. Low frequency array probe are usually constructed by large pitch element. In the case of linear scanning, the low frequency array probe could not obtain enough number of sound beams which construct a precise B-Scope image owing to non-dense arra...

Gel Immersion Technique Phased Array UT SAFT Ultrasonic
Inspection technique for complex surface profiles has been required in order to ensure the reliable operation and high operating rate of nuclear power plants, because many parts due to inspection have complex geometry. We have developed Pha sed Array (PA) ultrasonic testing with immersion technique which suitable to complex geometry. In this paper, we developed precise inspection technique for curvature surface profile such as a nozzle of pressure vessel. For curved surface pro file, Synthesis Aperture Foc...

Gel Immersion Technique Phased Array UT SAFT Ultrasonic Testing
Phased Array Ultrasonic Testing (PAUT) techniques for complex geometries are greatly progressing. We developed an immersion PAUT which is suitable for complex surface profiles such as nozzles and deformed welded areas. Furthermore, we have developed a shape adaptive beam steering technique for 3D complex surface structures with conventional array probe and flexible coupling gel which makes the immersion beam forming technique usable under dry conditions. This system consists of 3 steps. Step1 is surfac...

Complicated shape part Linear scanning Phased array Ultrasonic testing
Recently, an application target of the phased array ultrasonic testing (PAUT) has been extended. However, it was known that PAUT was difficult to apply to components with complex and high damping materials such as cast austenitic stainless steel (CASS). The Authors have developed shape adaptive beam forming PAUT system for complicated shape parts and comprehensive PAUT conditions analysis system for CASS. Each PAUT systems based on full matrix capture (FMC) technique. In order to enhance an applicability of...
