Abstract: The automobile in factories is one kind of special equipments. Based on national requirements, the automobile in factories is forced to perform supervision inspection. Most of the inspection items are nondestructive examination. The nondestructive testing(NDT) technique plays one of the most important roles for insuring manufacturing quality and transportation safety for the automobiles in factories. Several kinds of NDT technique for the automobiles in factories are introduced. At same time, their purposes are expressed. These NDT technique includes visual inspection, ultrasonic testing, surface testing, noise testing, velocity testing, redirector parameters testing, fluid drive system testing and so on.
