New desires and applications for waived-based NDT in power plant boilers

Not only progression of technology will not be conducive in development of construction building processes ranging from forming and welding processes as well as development of advanced substances having properties such as high proportion of strength to density without modern processes of inspecting welding about the reliability of the final product, but also may cause irreparable damages. In order to do so, the modern method of Phased Array Ultrasonic, having potential abilities, has been invented to be substituted with radiographic inspection which has been a common but old method of assessing quality of production and welding of different parts. In this article, we are to check the possibility of substituting the new approach (Phased Array Ultrasonic) with the former laborious method in all four prominent power plant connection plans. Besides several advantages Phased Array Ultrasonic has on offer, it should be proved to big industries that it is a reliable method capable of being replaced with the radiographic method fully which is really a method full of faults
