This document discusses different types of inspections used during the manufacturing process. It outlines floor inspection, fixed inspection, key point inspection, and final inspection. It then describes various inspection methods like visual testing, liquid penetrant testing, magnetic particle testing, ultrasonic testing, and radiographic testing. The objective of inspection is to check that a component works as intended, check the acceptability of manufactured products, and measure quality against predetermined standards. Inspection helps reduce defects, eliminate defective components, and ensure product quality.

ENSURE THE QUALITY OF PRODUCT

PREVENT FURTHER WORK ON SEMI FINISHED
PRODUCT ALREADY DETECTED AS SPOILED

MAKES OPERATION SAFE

DETECT SOURCES OF WEAKNESS AND TROUBLE
IN FINISHED PRODUCT

BUILTS UP THE REPUTATION

REDUCING NUMBER OF COMPLAINTS

CATCHING ERRORS DURING PROCESS
 SAMPLE
OF WORK IS CHECKED OF VARIOUS
MACHINE OPERATOR OR WORKERS
 CHECKING
IS DONE BEFORE THE FINAL

 ELIMINATES
CENTRALIZATION

7. •
WORK IS BROUGHT TO INSPECTOR TO CHECK
•
DISCOVERS DEFECTS AFTER THE JOB HAS
BEEN COMPLETED
•
WHEN INSPECTION TOOLS CAN NOT BE
BROUGHT TO THE SHOP FLOOR
•
SORT OF CENTRALIZED INSPECTION

8. o
KEY POINT IS A STAGE BEYOND WHICH IT IS
NOT CAPABLE OF REWORK
o
EVERY PRODUCT HAS A KEY POINT IN ITS
PROCESS OF MANUFACTURE
o
IT AVOIDS FURTHER EXPENDITURE ON POOR
PARTS

PERFORMANCE
 DESTRUCTIVE
AND NON DESTRUCTIVE
INSPECTION METHODS SUCH AS
TENSILE, FATIGUE, IMPACT, TENSILE ETC.,ARE
AVAILABLE FOR FINAL INSPECTION.
 FINAL
INSPECTION IS THE CENTRALIZED
INSPECTION

12. o
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.

13.  Process:
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
relatively economical.
 Limitations: Surface flaw detection only. Part
surface requires a thorough cleaning or
etching.


14.  Process:
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
sensitivity.
 Limitations: Method is restricted to a select
group of ferromagnetic test materials only.

15.  Process:
Transmit high frequency sound
waves vibrations into the test material,
 Sound reflections caused by flaws produce
displayed signals.
 Advantages:
Surface and deep subsurface
flaw location detection capabilities.
 Limitations:
Part geometry, flaw orientation.

16.  INSPECTION
IS VERY IMPORTANT BEFORE OR
AFTER MANUFACTURING THE PRODUCT OR
SERVICE TO ENHANCE THE QUALITY AND
GROWTH OF THAT ORGANISATION .
