Non-Destructive Testing (NDT)

Eddy Current Testing
This is a method that uses electromagnetic induction to detect surface defects in bars. In ECT, a magnetic field is generated that induces eddy currents on the bar's surface. Disruptions in these currents indicate potential flaws such as seamlines or cracks. It is particularly valuable for identifying minute surface flaws that may not be visible to the naked eye but can impact performance in demanding applications such as automotive, aerospace and medical components.
We conduct Eddy Current Testing for bars ranging from 5 mm to 45 mm
Ultrasonic Testing
This method uses high-frequency sound waves to inspect internal defects. In UT, ultrasonic waves penetrate the material, and any disruptions in the wave path, caused by cracks, voids, or other irregularities, are recorded and analysed. This technique is highly effective for detecting flaws deep within the bar, offering precise information on the location and size of imperfections.
We conduct UT for bars sized 15 mm and above


Magnetic Particle Inspection
Used primarily for ferromagnetic materials, MPI detects surface discontinuities such as cracks, seams, and inclusions. Used primarily for ferromagnetic materials, MPI detects surface discontinuities such as cracks, seams, and inclusions. A magnetic field is induced into the bar, and iron particles are applied, these cluster at any flaw, making it visible under UV or visible light.
