The detection of defects in thick butt joints in the early phase of multi-pass arc welding would be very valuable to reduce cost and time in the necessity of reworking. As a non-contact method, the laser-ultrasonic technique (LUT) has the potential for the automated inspection of welds, ultimately online during manufacturing. In this study, testing has been(More)
Boiler piping of fossil-fuel combustion power generation plants are exposed to high-temperature and high-pressure environments and failure of piping due to creep damage has been a concern. Therefore, a precise creep damage assessment method has been needed. This paper proposes a nondestructive method for creep damage detection of piping in fossil-fuel(More)
