Nondestructive (NDT) service include service companies that specialize in providing a variety of non-destructive service techniques. NDT service includes those test methods used to examine an object, material or system without impairing its future usefulness. Non-destructive testing service methods or nondestructive technology used by providers of non-destructive testing service include acoustic emission, nondestructive beta gauge, eddy current or electromagnetic, magnetic (induction / Barkhausen), magnetic particle system nondestructive, optical (shearography / holography / magneto optical), Penetrant testing systems, radiographic / X-ray imaging of nondestructive, ultrasonic, and other specialized service techniques. Depending on the method and measurement service requirements, non-destructive testing can be used off-line in laboratory environments as well as in continuous production line or field monitoring nondestructive applications. If a break, deformation or other failure occurs in a piece of equipment, sensitive acoustic emission sensors can detect the high frequency burst given off during the event. In a Beta gauge non-destructive testing, the absorption of Beta particles is used to measure the thickness of materials or coatings. Eddy current, penetrating radar and other electromagnetic techniques are used to detect or measure flaws, bond or weld integrity, thickness, electrical conductivity, detect the presence of rebar or metals. The eddy current method is the most widely applied electromagnetic NDT technique. Several different magnetic techniques are used in nondestructive including Hall effect and induction. In a magnetic particle non-destructive testing system current flow or an external magnet magnetizes the non-destructive part. Magnetic poles created at nondestructive flaws, cracks or other discontinuities attract nondestructive magnetic particles. Optical based non-destructive instruments using methods such as laser shearography, magneto-optical, holographic interferometry or other optical techniques to detect flaws, residual stress or measure thickness. In penetrant, Penetrant is applied to the part by spray or immersion. The penetrant is pulled into surface flaws by capillary action. Radiographic or x-ray equipment uses penetrating X-rays or gamma rays to capture images of the internal structure or a part or finished product. The density and composition of the internal features will alter the intensity or density of these features in the X-ray image. Ultrasonic (UT) inspection techniques are used to detect surface and subsurface flaws or to measure thickness. Choices for form factor include bench or rack or cabinet, computer board, portable or handheld or mobile, and monitoring system. Beams of high frequency acoustic energy are introduced into the material and subsequently retrieved. Areas of application for nondestructive (NDT) services include aerial or crane, automotive, aviation or aerospace, coatings or nondestructive platings, piping or pressure vessels, welding or nondestructive fabrication, and structural or construction.
