Non-destructive testing, inspection and inspection of the materials or parts to be done without damaging the integrity of the inspection. The results of non-destructive testing are evaluated based on the results of previous destructive testing.
As a matter of fact, this method does not cause any physical damage to the internal structures and the outer surfaces of the materials and parts tested during the inspection and inspection works. With the development of technology, higher quality production and increased service safety, today, non-destructive testing methods are given more weight. Different non-destructive testing methods have been developed due to the fact that the devices used in these studies are more accurate in identifying errors, the results are obtained faster, the operating costs are lower and the devices are easily portable. It continues to develop further.
Non-destructive testing methods are generally used to detect invisible discontinuities in materials or discontinuities open to the material surface. These methods are used to measure the amount of other materials contained in a closed material, as well as defects and defects in materials, to determine the status of assembled parts and to measure paint thickness on metal surfaces.
Non-destructive testing by inspection and testing organizations in general The following services are provided:
- Visual inspection (VT)
- Penetrant inspection (PT)
- Magnetic particle inspection (MT)
- Ultrasonic examination (UT)
- Radiographic examination (RT)
Visual examinations are performed mainly with the naked eye. Discontinuities on the surface of the products, factors affecting quality and structural defects are examined. It is a very simple technique, but in other non-destructive testing methods, this method should be applied first and visual findings should be recorded.
Penetrant inspections only detect defects on the outer surfaces of the materials. However, penetrant inspection is not performed for porous materials. The penetrant liquid is sprayed onto the surface of the material and fills cracks. The liquid is then removed from the surface and the cracks are examined visually or under black light.
Inspections with magnetic particles are used for the inspection of materials with magnetizing properties. Magnetic, electrical and geometric discontinuities of materials are measured with this method.
Ultrasonic examinations are performed by sending ultrasonic sound waves to the material to be checked and examined. With this method, problems are detected on the surface or inside of the materials. It is generally used to determine the thickness of the materials. For example, corrosion in the pipe is detected by this method.
Radiographic examinations are performed by sending X or gamma rays, that is, very high wavelength but high energy rays to the material to be checked and examined. With this method, the materials used to process the various materials are controlled. Thanks to these rays, different details are observed. Changes in radiation intensity give an idea about the thickness and composition of the materials.
No matter which method is applied, material examinations are performed to determine the properties of the materials, to make the material selection correct and to determine whether the selected materials will perform the expected function correctly.
Our company is non-destructive inspection services in accordance with the relevant legal regulations, standards and test methods published by domestic and foreign organizations.
