Training & Certification Course in NDT
We are providing Level I and Level II Training and Certification as per Recommended Practice SNT - TC-1A 2006 in the following NDT Method.
In Ultrasonic Testing high-frequency sound waves, created by a vibrated crystal in probe, are transmitted into a material to detect imperfections or to locate changes in material properties.
The most commonly used ultrasonic testing technique is pulse echo, whereby sound is introduced into a test object and reflections (echoes) from internal imperfections or the part's geometrical surfaces are returned to a receiver This method is very sensitive to detect crack type defects but requires extensive training for operator to interpret the result

UT Level 2 Practical Training
Same as for Level 1 course + Interpretation, Evaluation of Indications using DAC. Evaluation Methods and Echo Dynamics, Beam Profile and Plotting In ultrasonic testing (UT), very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz and occasionally up to 50 MHz are launched into materials to detect internal flaws or to characterize materials. A common example is ultrasonic thickness measurement, which tests the thickness of the test object, for example, to monitor pipework corrosion.
Ultrasonic testing is often performed on steel and other metals and alloys, though it can also be used on concrete, wood and composites, albeit with less resolution. It is a form of non-destructive testing used in many industries including aerospace, automotive and other transportation sectors.
