KINDS OF INSPECTION
KEY POINT INSPECTION
METHODS OF INSPECTIO
ACT OF CHECKING WHETHER A COMPONENT
ACTUALLY DOES ITS WORK AS DESIRE……….
CHECKING THE ACCEPTABILIT OF

BROUGHT TO THE SHOP FLOOR
SORT OF CENTRALIZED INSPECTION
KEY POINT IS A STAGE BEYOND WHICH IT IS
NOT CAPABLE OF REWORK
EVERY PRODUCT HAS A KEY POINT IN ITS
PROCESS OF MANUFACTURE
IT AVOIDS FURTHER EXPENDITURE ON POOR
CHECK ITS APPEARANCE AND
AND NON DESTRUCTIVE
INSPECTION METHODS SUCH AS
TENSILE, FATIGUE, IMPACT, TENSILE ETC.,ARE
AVAILABLE FOR FINAL INSPECTION.
INSPECTION IS THE CENTRALIZED
Inspection That Discovers Defects
Inspection That Reduces Defects
Inspection That Eliminates Defects
inspect the surface of the material for any
indications of a discontinuity or interruption
in the normal surface configuration.
Dimensional measuring and optical aid tools
may be used.
Advantages: To make the best judgment for
the method and technique used.
Limitations: Surface inspection only. Difficult
to find small cracks.
Apply a penetrating liquid to the
test material surface, Remove, Dry, Develop
and the Inspect part.
Advantages: A wide variety of materials can
be tested. Inspection is simple, fast and
Limitations: Surface flaw detection only. Part
surface requires a thorough cleaning or
Magnetize part and apply iron oxide
particles to the part surface.
Flaws will attract particles giving an
indication of the location of the flaws.
Advantage: Surface and near subsurface flaw
detection potential and linear indication
Limitations: Method is restricted to a select
group of ferromagnetic test materials only.
Transmit high frequency sound
waves vibrations into the test material,
Sound reflections caused by flaws produce
Surface and deep subsurface
flaw location detection capabilities.
Part geometry, flaw orientation.
IS VERY IMPORTANT BEFORE OR
AFTER MANUFACTURING THE PRODUCT OR
SERVICE TO ENHANCE THE QUALITY AND
GROWTH OF THAT ORGANISATION .
