Profile: Scanstar NDT Services is a non-destructive testing service provider in the field of aerospace, automotive, corrosion, industrial plants, oil, gas, petroleum, power generation and chemical plants. We are an ISO 9001:2000 certified company. We offer various services including ultrasonic flaw detection, magnetic particle inspection, penetrant inspection, ultrasonic thickness gauging, eddy current inspection, infrared & thermography, vibration analysis, radiographic inspection, NDT training & certification program, and radiographic inspection. Ultrasonic inspection uses high frequency sound waves to detect imperfections or changes in properties within the materials. It can also be used to measure the thickness of a wide range of metallic and non-metallic materials where access from one side is available. In eddy current testing, electrical currents are generated by a conductive material due to an induced magnetic field. Distortions in the flow of the electric current (eddy currents) caused by imperfections or changes in a material’s conductive properties will cause changes in the induced magnetic field. These changes, when detected, indicate the presence of the imperfection or change in the test material. Magnetic particle inspection is used to identify surface and near surface discontinuities in ferromagnetic materials such as steel & iron. The technique uses the principle that magnetic lines of force (flux) will be distorted by the presence of a discontinuity. Discontinuities are located from the flux distortion following the application of fine magnetic particles to the area under test. Radiography uses an x-ray device or radioactive isotope as a source of radiation which passes through the material and is captured on film or digital device. After processing the film, an image of varying density is obtained. Possible imperfections are identified through density changes.
