The so-called radiographic inspection is a method of using radiation to check the internal defects of the weld. The rays can pass through the metal material to varying degrees and produce a photosensitive effect on the photographic film. Using this property, when the ray passes through the inspected weld, due to the different absorption capacity of the weld defect to the ray, the intensity of the ray falling on the film is not the same, and the film sensitivity is not the same, so that the shape, position and size of the defect can be accurately, reliably and non-destructively displayed.

Test Range
All kinds of pressure vessels, boilers, hulls, oil and gas pipelines and other welds, all kinds of cast steel valves, pump bodies, oil drilling and chemical, oil refining equipment in the pressure castings, precision casting turbine blades, aviation and automotive industry for all kinds of aluminum magnesium alloy castings.
