NDT Level II QA/QC Course in Hyderabad | Vizag | Hyderabadfuturendt
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/
Nondestructive Testing (NDT) has evolved from being a “necessary evil” to being an essential source of competitive advantage. The right technique not only helps control the quality of the final product, but also provides valuable process control feedback to improve productivity, reduce cost, and increase the
efficiency of the welder. This is especially important in high-volume, continuous processing lines where a few minutes of bad production can result in significant losses.
In the last decade, powerful Ultrasonic EMAT technology has come of age with tremendous success, becoming the technique of choice for many applications.
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
Welding is a common joining process used extensively
in automobile industries, aircraft machine frames structural
work ship building and various other fields. The physical
properties of these welds are influenced by several factors. In
order to produce satisfactory weldments which fulfill the
requirement of quality the integrity of quality control is
important. To understand the various defects, their causes and
remedies can help to ensure higher quality and longer lasting
welds. This report contains essential information of surface
irregularities and weld discontinuities. Non destructive testing
(NDT) is a mechanism which helps in finding out of defects of any
item like welds before major harms happen to the item without
affecting its usefulness. This thesis discusses the non destructive
testing of weld structures. There are more than fourteen methods
of NDT in metals, in this thesis the most important ones-Visual,
Ultrasonic, X-ray and penetrant testing are discussed in detail.
The experimental results are discussed and comparisons are
made based on cost, accuracy, safety, time consumption, etc.
Based on these comparisons conclusions and recommendations
are made.
Advance NDT method are much efficient than conventional NDT methods. these methods have great amount of automation which help in understanding and comparing the data occupied by different reading. These data can be used for the future references and can be saved and stored. these Advance NDT method can test or inspect any shape such as complex shape very easily and effeciently.

5. The earliest and most useful method of NDT is
visual examination. Important details can be collected
during VT which would be useful for future analysis
and also to decide on the types of NDT to be used for
as further analysis. Also, VT should be carried out as
a complementary method to all other NDT methods.
VT should proceed and succeed all other
examinations. Inaccessible areas can be inspected by
means of boroscope and fiber-optic techniques.
Depending upon the severity of the surface defect
and the component in use, decision will be taken for
salvaging the component or not. If the product is
found unacceptable during visual examination itself,
further NDT need not be carried out, thus saving
time and cost of inspection
6. Surface deposits
Scaling
Corrosion
Discoloration
Oxidation bulging
Missing parts
Mechanical damage
Dimensional conformance
Gross effects visible on the surface
Distortion of components during fabrication and in
services
General corrosion on the surface of a component
7. Liquid penetrant testing (LPT) is another means of enhancing the
capability of visual examination. It is suitable for use on smooth
surfaces of all materials, magnetic as well as non-magnetic. It is
limited to surface defects. Its inability to indicate the depth or
breadth of flaw should be kept in mind while selecting this
method for particular application.
Use of LPT for porous materials is ruled out since the absorption
into the pores would mask the presence of defects. A clean surface
is a pre-resist as penetrant cannot enter in to the cracks that are
filled with dirt, oil, or other matter.
Size, shape, weight and number of workpieces to be inspected
often influence the selection of a penetrant system. The desired
degree of sensitivity and the cost are the most important factors in
selecting a system.
LPT can also be used for leak testing. In this case, the component
casting is filled with penetrant and developer is applied outside
the surface.
8. LPT is selected for detecting the following types of
discontinuities on the surface of a component.
Cracks of any orientation
Porosity
Pin holes
Voids
Forging laps
Forging bursts
Lamination in plates
Various types of weld defects
Corrosion cracks
Creep fissures
Fatigue cracks
9. While LPT is effective only for fine surface discontinuities, the need
remains to detect larger surface flaws or those present just below the
surface. The need is met by magnetic particle testing (MPT). This
technique is applicable only for ferromagnetic materials. MPT is a
considered more sensitive than LPT. MPT requires a higher degree or
operator expertise to ensure that the magnetic fields are aligned in the
correct direction in order to detect the defect. Flaws oriented
perpendicular to the induced magnetic field is only reliably detectable.
Hence the challenge is to induce magnetic field lines in a given work piece
so that they are most likely to be perpendicular to the flaw orientation.
Therefore, prior knowledge on flaw orientation and or introduction of
magnetic fields in several directions are is essential.
It is commonly agreed that defects breaking the surface are most severe
amongst the various discontinuities occurring in components. For
dynamically loaded structures, their removal is essential. Their detection
in ferrite materials is most easily accomplished by MPT. Since the depth
determination of the surface breaking cracks is almost impossible, crack
depth measurements may be additionally employed to asses them.
Detection of subsurface defects by MPT is impossible if the components
are thin, but generally it requires ideal testing conditions.
10. MPT is used for detecting following discontinuities in ferromagnetic
materials.
Surface discontinuities:
Cracks and tears
Porosity
Shrinking cavities
Slag inclusions
Voids
Forging laps
Grinding cracks
Corrosion cracks
Fatigue cracks
Discontinuities just below the surface (within around 6mm depth from
the surface sensitivity goes down as a defect is deeper):
Larger size cracks in various orientations
Pores
Slag inclusions
11. The other NDT methods are used for detection of defects
which are open to the surface nearer to the surface. To
detect more deeply seated discontinuities, NDT methods
with test medium capable of deeper penetration and
system that senses even minute changes in the
characteristics, behaviour of the test medium is required.
Radiographic inspection is one of the most widely used
methods of NDT as this is applied to all metals and
alloys, both ferrous and nonferrous, for detection of
volumetric type of defects. The range of capabilities
offered by the variety of sources and equipments has
brought radiography to the forefront of NDT techniques.
Testing of multilayer vessels and welds is generally a
difficult task due to in accessible inner layers. RT is the
only NDT method to evaluate multilayered vessels
during manufacturing stages and inservice.
12. Development of micro focal X-ray units has made it possible
to extend radiographic practice to meet the requirements of
more stringent quality levels demanded for critical
applications, besides a host of new applications. It is know
that the sensitivity in radiography depends to a large extend
on the focal spot size. In micro focal radiography, the focal
spot size is less than 100microns and typically 15-50 micron
as compared to a few mm or ½ a mm in conventional
radiography. Using microfocal RT, intricate geometrical
components such as tube to tube sheet. Welds can be tested
with a sensitivity of even 1% of wall thickness 0-3mm.
microfocal RT can be used for detection of micro cracks of
around 25micron in size. Another application of microfocal
RT is to check the integrity of micro-welds used electronic
integrated circuits.
One of the advantages of RT is that no prior preparation of
the surface of the component is necessary. The main
disadvantage of the RT is the possible hazards due to
exposure to radiation if proper care is not taken.
13. RT is selected to detect and size the following types of
discontinuities
Cracks (parallel to the radiation beam)
Volumetric defects such as slag inclusions, voids etc:
Porosity
Blockages or deposits inside the pipe lines are
pressure vessels
Material thickness
To detect hidden foreign material inside a component
14. Ultrasonic testing involves use of high frequency sound waves
coupled to the components to be inspected and studying the
reflection pattern of these waves. UT is finding increased
applications in various industries. Several wave modes such as
longitudinal, shear and surface waves can be used depending
on the orientation and location of the discontinuities. Different
techniques such as pulse-echo, through transmission, and
pitch-catch or employed. The advantages of UT are real time
availability of results, higher penetrating power of these
waves, higher sensitivity for planner defects, independence
sensitivity over depths, low cost for inspection, higher
portability to the equipment and compatibility for automation.
But the subjectivity of the results on the operators training and
skill is stumbling block for its wider acceptance. With the
advent of microprocessors and automation, operator
dependability is being eliminated to a larger extent and UT
finding increased applications in industries such as power,
railways, chemical, aerospace etc:
15. UT of cast metals and alloys is renderd difficult due to
the influence of casting intricacy, micro structural
variations and surface roughness. Defects occurring in
the cast structure have irregular surfaces which scatter
the aquostic waves and makes UT more difficult. Hence
successful use of UT for inspection of castings depends
greatly upon the skill and expertise of the operator.
UT is the most suitable method of NDT for inservice
inspection (ISI) of components in power plants, chemical
process industries, etc:. Many times, RT cannot be
applied for ISI due to the requirements of two side
accessibility. UT is more sensitive flaw growth
monitoring has compared with RT in view of all these
advantages; the first choice of ISI is UT for volumetric
defects in components except for heat exchangers and
condensers where ECT is preferred.
16. UT Is Selected To Detect The Size The Following Type
Of Discontinuities
Surface breaking and hidden cracks in any orientation
Inter granular cracks
Laps
Laminations
Volumetric defects such slag inclusions, voids, ect
Porosity
Wall thickness measurements
Creep
Hydrogen encriptment
Liquid level measurement
To detect blockages, deposits, etc. in the pipe lines and
pressure vessels
