We conduct NDT certification as per the requirements of ASNT – SNT TC 1A 2006, which uses non-invasive techniques to determine the integrity of a material without impairing its usefulness.For more details visit: http://www.futurendt.com/
It useful for ndt student to achieve the methods of NDT (NON-DESTRUCTIVE TESTING) and easy langauge is used for students to catch the methods of NON DESTRUCTIVE TESTING
Testing comprise all the techniques of materials or products under different types of loadings. This way, the reliability of product to end user is assured and the process of material selection is done with a lot of ease.
Testing can be classified in two main categories depending upon destruction of products as
Destructive Testing
Non-Destructive Testing
These comprises all those techniques which are highly regulated on some standard in which specimen is broken/destructed.
Major destructive testing used these days are
Tensile Testing
Impact Testing
Burst Testing
Fatigue Testing
Creep Testing
Non-destructive testing (NDT) is a wide group of analysis techniques used in science and industry to evaluate the properties of a material, component or system without causing damage.
Another terms for NDT is NDE
Highly valuable technique that can save both money and time in product evaluation.
Accident prevention and to reduce costs
To improve product reliability
To determine acceptance to a given requirement
To quick information on repair criteria.
Visual Inspection
Acoustic Emission
Eddy Current
Liquid Penetrant
X-Ray/ Radiography
Magnetic method
Visual and optical inspection (or testing) is still a basic method for many applications. Visual inspection involves using an inspector's eyes to look for defects. The inspector may also use special tools such as magnifying glasses, mirrors, or bore scopes to gain access and more closely inspect the subject area. Visual examiners follow procedures that range from simple to very complex.
Detection and analysis of AE signals can supply valuable information regarding the origin and importance of a discontinuity in a material.
It has many industrial applications
Assessing structural integrity (Welding)
Detecting flaws
Testing for leaks (Pressure Vessel)
Monitoring weld quality
Research tool.
In a standard eddy current testing a circular coil carrying current is which generates eddy current then the presence of any flaws, will cause a change in eddy current and a corresponding change in the phase and amplitude of the measured current.
Applications:
Surface Breaking Cracks
SBC using Sliding Probes
Tube Inspection Conductivity
Heat Treat Verification
In it the defects/cracks are studied using a penetrant/dye. low surface tension fluid penetrates into clean and dry surface-breaking discontinuities. Penetrant may be applied to the test component by dipping, spraying, or brushing. After adequate penetration time has been allowed, the excess penetrant is removed and a developer is applied. The developer helps to draw penetrant out of the flaw so that an invisible indication becomes visible to the inspector. Inspection is performed under ultraviolet or white light
X-rays are just like any other kind of electromagnetic radiation. They can be produced in parcels of energy called photons, just like light.
These are used to produce image
NON DESTRUCTIVE TESTING TECHNIQUES ARE USEFUL FOR FINDING DEFECTS LIKE CRACKS,POROSITY,FLAWS,BLOWHOLES IN MATERIALS WITHOUT DESTRUCTING COMPONENT. IT IS ALSO USEFUL FOR TAKING DECISIONS RELATED TO QUALITY OF MATERIAL OR PRODUCT. Non destructive testing includes study and testing of components by various methods such as dye penetration test, eddy current test, magnetic particle test, ndt, radiography test, ultrasonic test.
