What is a Nondestructive inspection equipment?

A non-destructive inspection device is a device that inspects the inside or surface of an object to be inspected without destroying or damaging it. The purpose of the inspection is to check for scratches, defects, cracks, voids (air bubbles), etc. that exist inside or on the surface of the inspection object. By this inspection, the manufactured product can be inspected without destroying it, and the reliability and guarantee of the product can be given. There are many types of non-destructive inspection equipment based on multiple principles, and they are used according to the characteristics of the inspection target and the purpose of inspection. In addition, there is a non-destructive test technician qualification test that makes full use of non-destructive inspection equipment and judges whether the inspection technology is satisfied according to the regulations for each of the 6 types of inspection categories.

Application of Nondestructive inspection equipment

"It is used to judge the presence or absence of penetration or welding defects inside the weld, cracks or cracks inside the material, defects such as voids, presence or absence of defects, and scratches or cracks on the surface of the material that cannot be visually identified.

Non-destructive inspection includes methods that do not require equipment (visual inspection, penetration flaw detection inspection, etc.), but inspection applications that require equipment include aircraft body inspection and steel frames inside concrete such as buildings, bridges, tunnels, and viaducts. It is used for aging inspection of steel pipes, copper and aluminum pipes during the production process, and inspection of containers and pipes in nuclear power plants. X-ray imaging, CT scan, and magnetic resonance imaging that inspect the human body are also non-destructive inspection devices.
