Non Relevant Ultrasonic Indications
Non relevant Ultrasonic Indications can usually be identified as one of the following: Electrical Interference Interference form the transducer (search unit) Interference form the surface of the specimen Interference caused by mode conversion of the sound beam Interference caused by the shape of the…

ISO Standards for Ultrasonic Testing
Ultrasonic Testing In Ultrasonic Testing we use something called “Ultrasonic Vibrations” we must know two facts about a vibration: A vibration is a back and forth movement. A vibration is energy in motion A depression of a surface from its normal position is called a displacement.

What is Acoustic emission testing?
ACOUSTIC EMISSION TESTING (AET) Acoustic Emission Test is a type of Non – Destructive Test method generally used for detecting and locating imperfections in mechanically loaded structures or components. Flaw origination and progression in a stressed component can be identified by acoustic emission test method.This…

Heat Treatment of Alloys
What is an Alloy? Since metals are insoluble in water, alcohol; they are mixed with other metals in molten state which upon cooling solidifies to a solid mixture called an Alloy. This solid state mixture is also referred as a homogeneous liquid mixture. Alloys are formed by…

Rebound Hammer Test-Non Destructive testing on Concrete
Non destructive testing for concrete Non Destructive Testing is the process of detecting the quality without destructing the material or without changing its actual properties. Rebound Hammer is also called as Schmidt hammer or Swiss Hammer or Concrete hammer test. This NDT method is used to detect…
