In Japanese Nuclear Power plants, many IGSCC had been detected in re-circulation line made of Stainless Steel. Therefore these piping welds have to inspect in short intervals. In addition the Japanese maintenance code had been published. The needs of crack depth sizing with high reliability is getting greater in Japan. IHI developed phased array technique for efficient crack detection, and the IGSCC depth sizing. The developed technique use the 2D phased array probe with wedge, and this probe can be applied for crack detection and crack depth sizing.
