ASNT NDT - LEVEL II - NON DESTRUCTIVE TESTING IN TRICHY
Non destructive testing standards provide guides for the appropriate methods and techniques used to detect and evaluate flaws in materials and objects without destroying the specimen at hand. Such tests include radiographic, ultrasonic, electromagnetic (eddy-current), X-ray, acoustic techniques. Detected flaws are evaluated for possible rejection due to non conformance to set acceptance criteria.
RADIOGRAPHIC TESTING
Using radioactive isotope (x-rays or gamma rays) a film is created, which we process in our laboratory or mobile darkroom. The results show defects which might otherwise be invisible. A vast array of material can be examined this efficient and reliable way—ranging from tiny electronic components to 20' freestanding concrete slabs.
MAGNETIC PARTICLE TESTING
Magnetic particle testing having ferromagnetic materials such as castings, weldments, turbine components, forgings, and machined or stamped parts, this is one of the most sensitive non destructive examinations. The sample is magnetized, and iron filings are applied, which adhere to any breaks in the magnetic field. Defects too small to be visible can be further examined with fluorescent inspection.
LIQUID PENETRANT TESTING
Liquid penetrant scientists and technicians apply dye to a sample and then examine it visually or under fluorescent light to locate defects. This is a quick, economical NDT test method and easily set up in the field with our portable equipment.
ULTRASONIC TESTING
Ultrasonic testing method, NDT inspectors only need access to one side of a material. A transducer sends the ultrasound through the sample and the inner wall of a defect surface will send the wave bouncing back. Ultrasonic testing can also measure thickness, detect corrosion, and examine groove welds, and it’s also very portable and efficient.
EDDY CURRENT TESTING
In Eddy current testing a flow of periodic electrical currents in conductors called probes creates varying electromagnetic fields. These probes are placed in close proximity to the surfaces of the test materials, and can detect effects of processing and shaping operations during production, as well as corrosion damage or cracking for most nonmagnetic metals and alloys. Eddy current is a cost-effective and portable NDT method.
VISUAL INSPECTION
Element Visual Inspectors receive specialized training to employ a number of high-tech devices, including a Charge-Coupled Device (an advanced imaging and color chip system) and a joystick-driven 50-foot long Steer Probe for very tight access, as well as training on advanced computer programs that accurately measure defects, voids, pits, corrosion, and wear, and store this information on a variety of media.
