Welding defects can be classified as structural discontinuities and consist of: porosity, slag inclusions, lack of fusion, cracks, etc.
Porosity is gas pockets or voids in the weld metal which are free of any solid materials, such as It is formed as a result…
NDT Course fees depends on the type of NDT Course Selected, such a number of methods and the International standard chosen for the certification
The Average course fees for General NDT course will be Rs.17500,
This course fees Rs.17500 is for ASNT Level II Certification course…
Here are some rarely used NDT – Few Other Methods
1. Eddy Current Testing – ET:
Eddy-current inspection uses electromagnetic induction to detect flaws in conductive materials. A circular coil carrying current is placed in proximity to the test specimen (electrically conductive). The alternating current in…
