Tata Steel NDT Engineer Interview Questions, Process, and Tips

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

• Ultrasonic testing is used to detect internal flaws or defects in materials such as cracks, voids, and inclusions.

• The procedure involves sending high-frequency sound waves through the material and measuring the time it takes for the waves to bounce back.

• The reflected waves are then analyze...read more

Ultrasonic testing uses high frequency sound waves to detect flaws or measure thickness in materials.

• Ultrasonic waves are sent into the material being tested

• The waves bounce back differently depending on the material's thickness or any flaws present

• The reflected waves are analyzed to determine the material's properties

• Commonly used in non-destructive testing of metals, plastics, and composites

LPT is Liquid Penetrant Testing used to detect surface defects. DP is Differential Pressure used to measure flow rate.

• LPT involves applying a liquid penetrant to the surface of a material and then removing the excess to reveal any surface defects.

• DP measures the difference in pressure between two points in a system to determine the flow rate.

• DP can be used in various applications such as measuring the flow rate of flui...read more

DAC stands for Digital Acquisition System, used in NDT to convert analog signals to digital signals for analysis.

• DAC is used in NDT to convert analog signals to digital signals for analysis

• It is an important component of the inspection system

• DAC is used to improve the accuracy of flaw detection and sizing

• It can be used in ultrasonic, eddy current, and other NDT methods

• DAC curves are used to calibrate the inspection sys

Acceptance criteria of UT refers to the minimum standards that a material or component must meet to be considered acceptable for use.

• The acceptance criteria of UT is based on the size, shape, and location of the defects found in the material or component being inspected.

• The criteria may vary depending on the industry and application of the material or component.

• The acceptance criteria may be specified in codes, standar...read more
