Vidial International NDT Inspector Interview Questions, Process, and Tips

NDT is needed to ensure the safety, reliability, and quality of materials and structures in various industries.

• Detecting defects in materials and structures

• Preventing failures and accidents

• Ensuring compliance with regulations and standards

• Extending the lifespan of equipment and infrastructure

• Saving costs by identifying issues early on

Magnetic inspection is a non-destructive testing method that uses magnetic fields to detect surface and subsurface defects in ferromagnetic materials.

• Magnetic particles are applied to the surface of the material being inspected.

• A magnetic field is then applied to the material, causing the particles to gather at areas of magnetic flux leakage.

• These gathered particles indicate the presence of defects such as cracks, incl...read more

Ultrasonic inspection is a non-destructive testing method that uses high frequency sound waves to detect flaws or measure thickness in materials.

• Uses high frequency sound waves

• Can detect flaws or measure thickness in materials

• Commonly used in industries like aerospace, automotive, and manufacturing

• Examples include detecting cracks in welds or measuring wall thickness of pipes

LPT inspection stands for Liquid Penetrant Testing, a non-destructive testing method used to detect surface-breaking defects in materials.

• LPT inspection involves applying a liquid penetrant to the surface of a material, allowing it to seep into any surface-breaking defects.

• After a certain amount of time, the excess penetrant is removed and a developer is applied to draw out the penetrant from the defects, making them v...read more
