X-ray test.

X-ray flaw detection is an important means of quality inspection, quality control and quality assurance in modern industrial production. It is generally used for non-destructive testing of metal and non-metal parts, casting and welding parts to determine their internal defects, such as slag inclusion, cracks, porosity, non-penetration, non-fusion and so on. It is widely used in machinery, petroleum, chemical industry, aviation, shipbuilding, defense and military industries, especially in the welding seam detection of boiler and pressure vessel.
