HOME / NON-DESTRUCTIVE TESTS
It is the examination of the parameters affecting the quality such as discontinuities on the surface of a product, structural defects, surface condition, with or without the use of an optical aid (such as a magnifying glass). It is usually a study that should be done before applying another non-destructive testing method. In this examination; magnifiers, markers, welding calipers, temperature measuring instruments, videoscopes, baroscopes/endoscopes, flashlights, etc. is done using The test method according to ISO 17637, ISO 5817 and ISO 10042 is applied as a quality assurance tool in almost every product. QUARCO A.S. NDT certified according to ISO 9712 / EN 473, in accordance with national and international standards, the quality of all kinds of manufacturing and materials, especially Pressure Vessels, Power Plants, Gas and Liquid Substance Transmission Lines, Steel Construction structures and constructions, Casting and Forging productions. It adds value to your projects and productions by increasing your productivity by detecting defects and problems in the earliest stages of production by our staff. Benefits and Features: If done before, during and after welding, many discontinuities can be detected without the need to apply other NDT methods, thus saving cost and time.
In this method, the penetrating liquid, which has penetrated into the open discontinuities on the inspection surface by capillary effect, is drawn back to the surface by the developer solution, and discontinuity signs are obtained. Liquid Penetrant Inspection can be used on all metallic or non-metallic materials and there are no cracks, pores, etc. open to the surface. errors can be detected. According to ISO 3452, ISO 23277 this method is used to examine various product forms including casting, forging and welding.
QUARCO A.S. While performing the Penetrant Inspection in accordance with national and international standards, it adds value to your projects and productions by using its expert staff certified according to EN 473 / ISO 9712, equipment in accordance with the standards, and solutions of brands with global leadership in this field (MR, PFINDER, etc.).
Benefits and Features:
• It is a very portable NDT method.
• Defects in non-metallic materials can be detected.
• It is a fast method, it can be concluded quickly.
• Can be applied to a wide variety of materials.
• Regardless of direction, all surface discontinuities can be detected with one operation.
In magnetizable materials, it is possible to detect surface and sub-surface discontinuities very quickly thanks to this method. For this, a magnetic field and magnetic powder sensitive to the leakage flux formed on the discontinuities are applied to the material. The dust becomes visible and evident by being held by the leakage area on the part surface. In this way, discontinuities such as cracks, voids, non-metallic residues can be detected. It is a very simple, fast and low-cost method used in the detection and location of defects on the surface and very close to the surface (just below the surface) without compromising the integrity and usability of the material in any way.
QUARCO A.S. While carrying out the Magnetic Particle Inspection in accordance with national and international standards, it adds value to your projects and productions with our expert staff certified according to EN 473 / ISO 9712, using equipment in accordance with the standards and solutions of global leaders in this field (MR, PFINDER, etc.).
Benefits and Features:
• Thin and shallow surfaces in ferromagnetic (materials with strong magnetism) materials are the best method for detecting cracks.
• It is one of the fastest and most widely used non-destructive testing methods.
• It has low test cost.
• It works even if there are thin layers of paint.
• It is a very portable method.
