The non-destructive testing industry has a history of several decades in China. With the development of the social economy, the non-destructive testing industry has involved various aspects of people's lives. Experts have stated that non-destructive testing is a sunrise industry with great potential for development, especially in China where the development prospects are very broad.

Domestic non-destructive testing equipment can be roughly divided into 26 categories, with over a thousand specific product models and varieties. Generally speaking, it has covered most of the fields of non-destructive testing technology applications in China, especially the equipment, devices, accessories, consumables, etc. for conventional non-destructive testing, which have basically reached the level of low cost and good quality and can meet general testing needs.
