Question

advantages and disadvantages of ultrasonic sound waves

​

Answer 1

Answer:

Answer: When a substance is heated, its molecular movement increases. Due to this, the average distance between the molecules also increases, thereby increasing the volume of the substance, i.e., expanding the substance. However, the movement of molecules depends upon the state of matter.

Answer 2

Advantages of Ultrasonic Testing Techniques:

• Ultrasonic testing has high sensitivity, high penetrating power that allows the detection of flaws deep in the part.
• it permits the detection of extremely small flaws.
• It has greater accuracy than other nondestructive methods in determining the depth of internal flaws and the thickness of parts with parallel surfaces.

Disadvantages of Ultrasonic Testing Techniques:

• Training is more extensive than other methods.
• More expensive than other methods.
• Difficult to use on thin materials.
• Part Geometry can cause complications.
• Needs relatively smooth surface to couple transducer.
