• The primary principle behind Ultrasonic Testing is the use of heat to detect internal flaws

Explain the difference between Radiographic Testing and Eddy Current Testing.

• Radiographic Testing uses X-rays to detect internal defects in materials, while Eddy Current Testing uses electromagnetic induction to detect surface and near-surface defects.

• Radiographic Testing uses sound waves to detect defects in materials

• Radiographic Testing uses electromagnetic induction to detect surface and near-surface defects

• Eddy Current Testing uses X-rays to detect internal defects in materials

What are the advantages of Eddy Current Testing over other non-destructive examination methods?

• It is unable to detect surface defects

• It can only inspect simple shapes and sizes of conductive materials

• It is not sensitive to small cracks and discontinuities

• Some advantages of Eddy Current Testing include its ability to detect surface and near-surface defects, its sensitivity to small cracks and discontinuities, and its capability to inspect complex shapes and sizes of conductive materials.

How does Magnetic Particle Testing work to detect surface and near-surface flaws?

• Magnetic Particle Testing works by using sound waves to detect flaws

• Magnetic Particle Testing works by heating the material to reveal flaws

• Magnetic Particle Testing works by applying a chemical solution to the material to highlight flaws

• Magnetic Particle Testing works by applying a magnetic field to the material being tested and then applying iron particles to the surface. These particles will be attracted to any areas where there is a surface or near-surface flaw, making the flaw visible for inspection.

What are the limitations of Liquid Penetrant Testing?

• Surface cleaning is not necessary

• Some limitations of Liquid Penetrant Testing include the inability to detect subsurface defects, the need for surface cleaning and the potential for human error.

• It can detect subsurface defects easily

• There is no potential for human error

Describe the process of Ultrasonic Testing for weld inspection.

• UT is only used in the automotive industry for weld inspection

• The transducer in Ultrasonic Testing sends electromagnetic waves into the material

• Ultrasonic Testing (UT) is a non-destructive testing method that uses high-frequency sound waves to detect internal and surface defects in welds. A transducer sends ultrasonic waves into the material, and the reflected waves are analyzed to identify any flaws. UT is commonly used in industries such as construction, manufacturing, and aerospace for weld inspection.

• Ultrasonic Testing uses low-frequency sound waves for weld inspection

What are the different types of radiographic techniques used in Radiographic Testing?

• Fluoroscopy, mammography, and bone densitometry

• Ultrasound radiography, MRI, and PET scan

• Thermography, endoscopy, and electrocardiography

• The different types of radiographic techniques used in Radiographic Testing are X-ray radiography, computed tomography (CT), and digital radiography.

Explain the concept of impedance plane in Eddy Current Testing.

• The impedance plane in Eddy Current Testing is a graph showing the resistance of the test coil
