Automated X-ray inspection is used in a wide range of industries and applications, predominantly with two major goals: Process optimization, i.e. the results of the inspection are used to optimize following processing steps, Anomaly detection, i.e. the result of the inspection serve as a criterion to reject a part (for scrap or re-work).
Visual inspection (VT), the most commonly applied NDT method, is quite often enhanced by the use of magnification, borescopes, cameras, or other optical arrangements for direct or remote viewing. The internal structure of a sample can be examined for a volumetric inspection with penetrating radiation (RT), such as X-rays, neutrons or gamma ...
Examples of this technology include eddy current, ultrasonic, dye penetrant, and X-ray inspections. By catching structural cracks when they are very small, and growing slowly, these non-destructive inspections can reduce the amount of maintenance checks, and allow damage to be caught when it is small, and still inexpensive to repair.
X-ray generators produce X-rays by applying a high voltage between the cathode and the anode of an X-ray tube and in heating the tube filament to start the electron emission. The electrons are then accelerated in the resulting electric potential and collide with the anode, which is usually made of Tungsten .
Vehicle emissions inspection station in Wisconsin. Arizona – biennially, in Phoenix and Tucson metro areas only, depending on age and type of vehicle. [27]California – biennially for all vehicles from out-of-state, regardless of age; and all vehicles made after 1975 which are more than six years old in all or some zip codes in 41 out of 58 counties.
X-ray radiography is similar to gamma-ray radiography but instead of using a radioactive source, it uses a high-energy bremsstrahlung spectrum with energy in the 5–10 MeV range [8] [9] created by a linear particle accelerator (LINAC). Such X-ray systems can penetrate up to 30–40 cm of steel in vehicles moving with velocities up to 13 km/h.
Industrial computed tomography (CT) scanning is any computer-aided tomographic process, usually X-ray computed tomography, that uses irradiation to produce three-dimensional internal and external representations of a scanned object. Industrial CT scanning has been used in many areas of industry for internal inspection of components.
The phrase "X-ray welding" also has an older, unrelated usage in quality control. In this context, an X-ray welder is a tradesperson who consistently welds at such a high proficiency that they rarely introduce defects into the weld pool, and are able to recognize and correct defects in the weld pool, during
