UT inspection is carried out on configurations of welds, whereby due to geometry and restricted access to either side of the area to be inspected, the radiographic examination cannot be done, or where UT is known to exhibit better detection capability. Subsurface irregularities and flaws can be detected by using a combination of immersion ultrasonic testing techniques. By using ultrasonic ‘A’, ‘B’ or ‘C’ scans on castings, forgings, composites and welds, we can detect defect indications to the most stringent inspection standards. An ultrasonic wave is sent into the material and the reflected wave is then analyzed. Flaws can be recognized by trained personnel on the instrument screen. Features of the flaw (like location, orientation, length, depth and height of the flaw) can then be identified and assessed

Magnetic particle inspection is a sensitive method of locating surface and some sub-surface defects in Ferromagnetic components. The basics processing parameters depend on relatively simple concepts. In essence, when a ferromagnetic component is magnetized, magnetic discontinuities that lie in a direction approximately perpendicular to the field direction will result in the formation of a strong ‘leakage field’. This leakage field is present at and above the surface of the component, and its presence is visibly detected by the utilization of finely divided magnetic particles. The application of dry or wet particles in a liquid carrier, over the surface of the component, results in a collection of magnetic particles at a discontinuity.

This method of testing is suitable for detecting defects open to the surface only and on any material that is essentially non-porous. Dye penetrant testing is widely used to detect surface breaking flaws in both ferrous and nonferrous parts. It can be used both on-site and in a laboratory application with either color contrast or fluorescent techniques. A bright-colored penetrant or a fluorescent ink is sprayed on the surface of the component to be inspected. The penetrant will be drawn into any surface imperfections or cracks. After the excess penetrant is removed, a thin layer of the developer is then applied. The penetrant will then be drawn out of the defects and made visible with the use of visible light or ultraviolet light, as appropriate.



Radiography is used extensively to reveal irregularities in a variety of product types, predominately welds, castings, structures, and composites. Most weldments of steel pipes in the energy sector require some method of testing to determine the quality of the welding. A common method of testing is by radiographic examination. Radiographic testing aims to record images of flaws introduced into the welds. These could be process defects (e.g. porosity, lack of fusion) or service-related conditions (e.g. corrosion-cracks). Radiographic inspection is carried out utilizing radioactive sources such as Ir-192, Se-75 or Co-60 and also with X-ray irradiating apparatus. Our engineers, inspectors, and technicians are highly experienced not only in the use of these radioactive sources and X-Ray equipment but also take pride in holding a clean safety record on all projects are undertaken.

VT Is the oldest and most common nondestructive testing (NDT) techniques. It is typically the first step in the examination process to inspect a variety of product forms including castings, forgings, machined components, and weld elements, according to the NDT Training & Test Center. Compared to other techniques, visual testing is low in cost and easy to apply and often eliminates the need for further types of testing. Some of the industries that use VT include structural steel, automotive, petrochemical, power generation, and aerospace.
