Our NDT testing methods
1. Visual inspection
A trained inspector checks the condition of the surface, weld appearance, corrosion and visible defects with the assistance of visual aids (magnifiers, borescopes). This is the rapid initial stage of any NDT program.
2. Liquid Penetrant Inspection
Both ferrous and non-ferrous components surface-breaking discontinuities (cracks, porosity) can be viewed with both dye or fluorescent penetrants. This is the best technique to use when carrying out inspection of welds, castings, and machined parts.
3. Magnetic Particle Inspection
MPI identifies surface, and slightly below the surface, flaws in ferromagnetic materials such as steel. It is frequently employed for welds, axles, and structural elements.
4. Ultrasonic inspection
High-frequency sound waves identify internal defects (cracks, inclusions, delamination). Additionally, we carry out ultrasonic thickness measurement using portable gauges to quantify wall thinning or corrosion.
5. Ultrasonic Thickness Gauge
A precise Nondestructive Testing (NDT) approach employed to gauge the thickness of diverse substances like metals, glass, and composite materials without the necessity of sectioning or inflicting harm. Its operation relies on propagating high-frequency acoustic waves down through the external layer to discern issues such as corrosion, material loss, or degradation from normal use. This particular examination guarantees the soundness and stability of structures, most notably within pipelines, storage containers, and various apparatus used in industry.
6. Radiography (RT)
X-ray or gamma radiography yields an internal image of components to pinpoint volumetric flaws like voids or internal cracks — frequently employed for critical weld inspection and castings.
7. Portable Hardness Test
Swift, on-site hardness measurements confirm the material’s condition and heat-treatment soundness, involving trivial surface disturbance.

Frequently Asked Questions (FAQ)
1. What is NDT testing?
NDT (Non Destructive Testing) constitutes a procedure for evaluating materials, welds, and various structures without damaging their fundamental integrity. NDT works to sustain the safety, dependability, and overall quality of components, even as they remain actively in use.
2. Why NDT test is important?
NDT (Non-Destructive Testing) holds significance as it permits engineers to evaluate the caliber, robustness, and dependability of various materials without causing any harm or modification. This process is instrumental in finding concealed defects such as fractures, rusting, or imperfections in welds before they culminate in component failures.
Through the timely discovery of these problems, NDT testing markedly enhances safety, cuts down on expenses for upkeep and repairs, and guarantees that parts comply with mandatory industrial specifications.
3. What is Radiographic testing in NDT?
Radiographic Testing (RT) within NDT represents a technique employed to scrutinize a material’s internal architecture without inducing any harm. The process operates by transmitting X-rays or gamma rays through an item and recording the resulting image onto film or via a digital sensor.
This resulting image reveals variations in material thickness or the presence of internal imperfections, assisting in the detection of fissures, voids, porosity, or foreign inclusions that might be completely unseen on the exterior. Radiographic examination enjoys broad application for inspecting welds, cast objects, and pressure containers, thereby guaranteeing the soundness and safety of vital components.
4. What is Ultrasonic testing in NDT?
Ultrasonic Testing (UT), within the domain of Nondestructive Testing (NDT), constitutes a technical method utilized for identifying interior structural flaws or, alternatively, determining material thickness through the deployment of high-frequency sound waves. A dedicated transducer, commonly termed a “probe,” injects these ultrasonic impulses into the material under examination. If these waves encounter a break—such as a crack or an internal void—a portion of the sound’s energy is immediately reflected back toward the sensing device, frequently referred to as the detector.
5. What is Visual testing in NDT?
Visual Examination (VE) within Nondestructive Testing (NDT) refers to the technique of thoroughly checking a material’s external surface to identify discernible defects such as stress cracks, oxidation, or structural distortions. This procedure is performed either without help or utilizing simple tools such as magnification lenses and dedicated visual instruments. Although basic in character, it constitutes a vital primary step that aids in the prompt recognition of problems and guarantees the complete integrity and safety of the components under inspection.
