In order to ensure that the coatings attached to the surface of the metal barrel have no defects such as delamination, slag inclusion, and air inclusion, non-destructive testing of the surface coatings of the metal barrel is required. Currently, most non-destructive testing equipment on the market is handheld, and the detection probe needs to be manually placed in the area to be tested for testing, which causes many problems:

[0003] 1. When the product area to be inspected is large or the number of products is large, manual inspection is slow and inefficient.

[0004] 2. The consistency of test results cannot be guaranteed for the same product, which depends entirely on the operator's testing experience.
