Abstract :
Stainless steel is widely used in nuclear plant. The stainless steel weld (SSW) defects are threat for reliability of a structure. To prevent these failures, eddy current pulsed thermography (ECPT) is proposed for defects detection, which indicates defects by hot spot caused by high resistivity of defects. A series of verified experiments are conducted to detect various SSW defects. The independent component analysis (ICA) is also utilized to remove the influence of weld inhomogeneity and enhance the defect information.
