NDT: Non-Destructive Testing

Non-Destructive Testing (NDT) comprises a set of physical and technological tests designed to detect potential defects in a piece or artifact without destroying it, ensuring its integrity after the inspection. 

Our laboratory boasts qualified personnel (Level II and III according to ISO 9712/SNT-TC-1A) for the following testing methods: 

• Visual Testing: Visual examination is the main non-destructive testing method specified by UNI EN ISO 9712. This method does not alter, change, or destroy the material but allows for the identification and classification of surface imperfections through direct observation or with the aid of lenses. 
• Magnetic Particle Testing: The magnetic particle method, known for detecting surface defects, can also identify defects below the surface. To perform the inspection, the piece to be examined must be ferromagnetic. The method is based on the leakage of magnetic flux caused by the magnetization of the piece at a Discontinuity. 
• Liquid Penetrant Testing: Non-destructive testing with liquid penetrants is used to verify the integrity of a sample by detecting surface defects using a liquid that infiltrates discontinuities. This method is based on capillarity and is ideal for quickly, economically, and accurately detecting cracks, porosity, and folds. 
• Ultrasonic Testing: Ultrasonic testing is a method that evaluates the interior of the material by detecting discontinuities through acoustic waves. This examination is essential to ensure the homogeneity and integrity of materials, revealing defects such as solid inclusions, gas pockets, or cracks. 
• Radiographic Testing: Radiographic examination is used to verify the integrity of welds and castings, as well as in other sectors such as the inspection of concrete structures. Using high-energy radiation such as X-rays or gamma rays capable of penetrating considerable thicknesses of steel, the examination produces two-dimensional images with variations in shades of gray on radiographic or digital supports. The variations in shades of gray in the images allow for evaluating the integrity of the component. 

Non-destructive testing can be performed both on-site and at the client's location. 

By conducting these tests at appropriate stages of the production cycle, the manufacturer can identify any defects and decide whether to reject the piece or correct the defect through repair, avoiding additional processing costs.
