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…
A study on the couplant effects in contact ultrasonic testing.
The primary purpose of a couplant is to provide a suitable sound path between the transducer and the test surface.Ultrasonic Testing couplants usage can be seen here
A couplant must effectively wet or totally…
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…
LIQUID PENETRANT EXAMINATION (PT)
Pentrant Testing is surface defects detection method, the method can be used on any material ( i.e: Ferrous/ non-ferrous, conductive/ non conductive, metals/ non metals)
But PT is limited to materials having porous surface or very rough surface.
PT can be carried out…
This blog will discuss types of discontinuities that can be evaluated with the ultrasonic testing in NDT method.
Discontinuities can be divided into three general categories inherent, processing and service
Inherent discontinuities are usually formed when the metal is molten.
Inherent wrought discontinuities relate to the…

ThermographyTesting – NonDestructive Testing Method that involves visualization of heat radiations from an object and the method is a non contact inspection technique, .
It is also simply called as IR – Infrared Thermography, Thermal Imaging technique or Thermography.
Penetrant Testing is one of the effective method for detecting surface flaws,.
It can be used on Metals, non-metals, plastics, ceramics & Glass.
Not suitable for Porous materials such as wood, bricks, concrete, & other non graded castings, sponge
