Abstract: As an important part of the machinery and equipment remanufacturing project, non-destructive testing is related to the service safety of the remanufactured products. The damage detection particularity in the remanufacturing of high-end equipment makes the non-destructive testing face challenges. The research on new technologies such as laser ultrasound, etc, which have high sensitivity and are easy to implement automated detection, has become the hot spot that the domestic and international non-destructive testing workers are concerned about. The characteristics of non-destructive testing for the remanufacturing of high-end equipment are summed up, the conventional non-destructive testing methods and comparative analysis are outlined, several research focuses of current non-destructive testing field are sketched, the problems and difficulties in the current nondestructive testing for remanufacturing are summerized, the development trend of non-destructive testing for remanufacturing of high-end equipment is pointed out, and eferential research interests for the future in-depth research on nondestructive testing for remanufacturing are provided.

Key words: High-end equipment, Non-destructive testing, Remanufacturing
