    Non-destructive testing methods are used to detect possible irregularities without damaging the physical structure and outer surface of the material. Today, as the reliability of material services increases and consumer expectations of higher quality products increase, non-destructive testing methods have begun to diversify and become widespread.

    No destruction

    Non-destructive testing methods more accurately identify material damage, perform control and inspection activities faster, and reduce operating costs for control and inspection work.

    In this way, many different non-destructive testing methods are developed and more advanced devices are produced. The main non-destructive testing methods are: visual inspection, liquid impregnation (penetrating liquid), magnetic particles, radiographic and radioscopic control (with X-ray), eddy currents, ultrasonic control, leakage test and sound control. The method to be applied depends on the type of material and the type of error required. These methods have superiority to each other and often complement each other.

    These methods include a number of inspections and tests that allow the material to be inspected without disturbing and altering the properties required for the intended use, without damaging the material and, if necessary, inspecting the entire material. Non-destructive testing methods determine at the beginning of production activities to determine the source of failure at the test site of the material and the facility has the ability to correct errors in a timely manner. This ensures the reliability of the final product. Furthermore, it is not necessary to take any sample from the material for these procedures.

    Non-destructive tests do not leave traces and damage to the material. In this regard, these test methods are applied to finished parts. Examination and inspection studies will determine whether the portion contains an error.

    Non-destructive testing methods are widely applied in the mechanical engineering sector, research and development studies, production control, quality control studies and service process evaluation.

    Non-constructive material studies are the most important part of quality control in companies. The tested materials are tested and inspected without damage and information is obtained on the dynamic and static structures of the product, causes of leakage, points of damage, dimensions of damage and especially the tension of the material.

    This method can be applied not only during production, but also after the product is used for a certain period of time. In this way, there are damages such as voids, cracks and a reduction in the cross-section of the internal structure of the material due to wear and corrosion.

    Inspection services performed by accredited inspection bodies include non-destructive inspection, testing and inspection works. our organization In this context, with a strong technological infrastructure and staff in this framework, non-constructive inspection services are mainly provided:

    Visual inspection (VT)

    Magnetic Particle Testing (MT)

    Penetrant Testing (PT)

    Radiographic examination (RT)

    Ultrasonic Testing (UT)

    Eddy Current (ET)

    Time of Flight Diffraction (ToFD)

    Phased Array Ultrasonic Testing (PAUT)

    and many more….
