NON DESTRUCTIVE TESTING(NDT)

Non Destructive testing is the technologyto

assessing the soundness and accessibilityof an

actual component without aecting the

functional

properties of the component.

HOW TO SELECT THE NDT METHODFOR DIFFERENT COMPONENTS

Based on the type of the component

Based on the type of material used

Based on the Design Criteria

Based on the experience of the NDT specialist

Based on the criticality of the component(Dynamic Class ! " #$

VISUAL EXAMINATION

%t is one of the best NDT techni&ue for

all composite components

%t is one of the best NDT method for

component made out of 'evlarmaterial.

ULTRA SONIC TESTING A-!1%? /9scan display is basically

a plot of amplitude versus time inwhich a hori@ontal baseline on anoscilloscope screen indicates

elapsed time while the verticaldeAections (called indications orsignals$ represent echoes

The /9scan display which is themost widely

used format can be used to

analy@e the type si@e and location
