2. Methods:
a) Visual
b)Ultrasonic
c)Eddy Current
d)Liquid Penetrant 
e)Magnetic Particle

➢Liquid Penetrant Inspection (LPI)
➢Magnetic Particles Inspection (MPI)
➢Eddy Current Inspection (EC)
➢Ultrasonic Inspection (UT)
➢Radiographic Inspection (X-Ray)

3.  Discontinuity is define by Interruption in normal physical structure or configuration of part while defects is Discontinuity, size, shape, orientation or location that make it detrimental in service life of parts or components

4. Liquid penetration 

5. Ultrasonic testing

6.
