10. NON DESTRUCTIVE TESTING LAB
LIQUID PENETRATE INSPECTION
• A liquid with high surface wetting characteristics is applied to
the surface of the part and allowed time to seep into surface
breaking defects. The excess liquid is removed from the
surface of the part.
• A developer (powder) is applied to pull the trapped penetrate
out the defect and spread it on the surface where it can be
seen Visual inspection is the final step in the process.
11. MAGNETIC INSPECTION
The part is magnetized. Finely milled iron particles
coated with a dye pigment are then applied to the
specimen. These particles are attracted to magnetic
flux leakage fields and will cluster to form an
indication directly over the discontinuity. This
indication can be visually detected under proper
lighting conditions.
12. RADIOGRAPHY
• The radiation used in radiography testing is a higher
energy (shorter wavelength) version of the
electromagnetic waves that we see as visible light.
The radiation can come from an X-ray generator or a
radioactive source.
• The part is placed between the radiation source and
a piece of film. The part will stop some of the
radiation. Thicker and denser area will stop more of
the radiation.
13. EDDY CURRENT TESTING
Eddy current testing is particularly well suited for
detecting surface cracks but can also be used to
make electrical conductivity and coating thickness
measurements. Here a small surface probes scanned
over the part surface in an attempt to detect a crack.
14. ULTRASONIC INSPECTION
High frequency sound waves are introduced into a
material and they are reflected back from surfaces or
flaws. Reflected sound energy is displayed versus
time, and inspector can visualize a cross section of
the specimen showing the depth of features that
reflect sound.
