In thermal cycle of Post Weld Heat Treatment, the weld parts are heated in furnace often at lower temperature range (where material is not liable to phase change), followed by cooling in furnace. Well it’s not that simple. In PWHT heating and cooling is carried out, in controlled mechanized way with specific heating and cooling rates. For this, a number of thermocouples are employed for the monitoring of cooling and heating process. There are four essential elements that must be fulfilled in order to carry out effective post weld heat treatment.

Heating Rate
Soak Temperature
Soak Time
Cooling Rate

1. Heating Rate
The weld material is allowed to heat with controlled heating rate because on the detrimental side if the heating rate is not monitored, the material will prone to stresses due to high temperature gradient. In order to prevent any high stress level and consequent cracking, it is a recommended practice to heat steel weld parts (for example Carbon Manganese Steels) with heating rate range from 60 – 200 degree Celsius per hour. Normally the monitoring of heating rate is started above three hundred (300) degree Celsius because below this temperature most steels have adequate strength to avoid distortion which can be caused by intensification of stresses. Moreover it is to be noted that heating rate is primarily adjusted according to the weld thickness.

 

2. Soak Temperature
It is a temperature range where the heated weld part is held for some time, to effectively reduce the stress level. Soak Temperature is set according to the type of material and normally ranges from six hundred (600) to seven hundred and sixty (760) degree Celsius.

3. Soak Time
It is a specific time during which the material is allowed to heat at sock temperature range, in order to provide uniform heat throughout the weld thickness. Most important question here is how to predict the time frame for soaking, to homogenize the heat throughout the material thickness. Well suitable soak time is essential for the reduction of undesirable stress levels and it is determined depending on the joint thickness. Normally the codes call for soak time, one hour 1h per 20-25mm thickness.

4. Cooling Rate
In like manner, cooling rate must also be monitored carefully, in order to avoid higher stress levels and consequent cracking due to large temperature gradients. After giving particular soak time and temperature the material is cooled down in furnace with the regulation of cooling rate by thermocouples. It gives a complete thermal cycle from heating to cooling. Again the monitoring is required from soak temperature to three hundred (300) degree Celsius. Below three hundred degree Celsius the thermally treated weld material has enough strength to countenance the temperature gradients.

PWHT is most common practice in steel fabrication industries and normally carried out using oil or gas burning furnaces. The fuel must be clean from contaminants that may harm the weld job. Type of steel and service applications are the major considerations for applying post weld heat treatment because there are some exceptional applications and grade of materials where PWHT may induce detrimental effects. However its intended use is, to relieve stresses in steel welding that is why it’s commonly referred to as Stress Relieving.


Non-destructive testing( NDT ) is defined as test which can be performed on a material, components and assembly without damaging them and without affecting its ultimate serviceability.Mining industry is one of the vital sector where NDT is extensively utilised right from the row material selection to the finish product to assure product reliability and further for service inspection for operational reliability. The prime objective of the NDT techniques is to ensure safety by detection of such cracks attributed to the manufacturing inefficiency or develop during mining operations.

NDT Applications in Mining Industry

There are four techniques in particular which are being used to evaluate cage suspension gear, haulage items, head gear pulley shafts etc. are as follows:

  1. Visual inspection.
  2. Magnetic particle testing.
  3. Fluorescent crack detection.
  4. Ultrasonic testing.

Visual Inspection:
This technique is conducted visually by naked eyes or with the help of magnifying glass for detecting any visible surface defects like material loss, scratches, indentation and wear due to fatigue or visible cracks developed due to poor manufacturing processes. Visual inspection are needed for every mining components before going for any other NDT techniques and subsequently putting it into service.

Magnetic Particle testing:
Magnetic particle testing is nondestructive method for detecting surface imperfections in ferromagnetic material.
The mining components are of ferrous material and ferromagnetic in nature and thus this method is best suited for revealing the fine surface and subsurface flaws. Magnetic detection in ferromagnetic materials depends on the distortion of the magnetic field in a magnetized mass of metal by the defect or the difference in the magnetic properties between the defect and the main body . This distortion of difference is revealed by sprinkling the components with dry magnetic powder or spraying with a liquid containing magnetic particles of Magnetic Iron Oxide in suspension.

Fluorescent Crack Detection:
Fluorescent crack detection technique has an added advantage over magnetic particle crack detection that there is no directional sensitivity to be considered. In this method components are tested in a fluid containing fluorescent substance and penetrates into the surface defects which are revealed by a short wave radiation ultraviolet lamp. The ultraviolet light is produced by a high intensity mercury arc or mercury vapour discharge lamp.

Ultrasonic testing:
This technique is used to reveal the internal flaw up to the depth of more than 1 mm from the outer surface. The flaw detector is based on the principle that a beam of ultrasonic frequency transmitted into a solid is reflected by discontinuities such as cracks or cavities. The reflectogram is picked up by a receiver placed on the same face as the transmitter. A second echo from the far face of the solid will also be received after an interval of time . This pulse echo techniques allows the detection of minute defect in ferrous and non-ferrous metallic object. All cage suspension gears attachments like Friction Wedge Type Rope Cappel, Safety Hook, Distribution plate , cage shackles etc. & Haulage Rope Cappel and also Head Gear Pulley Shaft are evaluated with this technique.

applications of ndt in mining indusrty

Electromagnetic Inspection:
Evaluation and assessment of structural integrity of steel wire ropes plays an important role in mining industry. In mine hoisting system wire ropes are subjected to different degradations by virtue of its service and environmental conditions. Premature failure of wire ropes results loss in personnel as well as heavy damage to the hoisting installation causing down time. Rope condition is evaluated by nondestructive technique after one month of this installation allowing a constructional stretch and this mother data is kept as a base for assessment of this condition on subsequent NDT investigations conducted on periodic interval.The two types of flaws i.e. localised flaws due to broken wires and distributed flaws due to corrosion and corrosion pitting are evaluated by Permanent Magnet dual function wire rope tester.
Non-Destructive testing of wire rope enables early detection of wear or corrosion and development of broken wires.

Non-destructive testing is the only suitable techniques to ensure safety of mine personnel during haulage transport and mine hoisting.Accident could have been avoided by knowing the flaws and its severity in mining components detected by NDTCareful maintenance and inspection of all winding components must be followed rigorously.


Non-Destructive Testing occupied very important role in recent times in industrial applications like Aerospace, aircraft overhaul, automotive, petrochemical and gas, railway, mining, agriculture, power generation, iron, shipbuilding, steel, pipe and tube manufacturing industries etc as a powerful quality tool. Mainly in Aerospace industry in view of high quality requirements safety and stringent Airworthiness requirements. All components are inspected before they are assembled into the aircraft and then they are periodically inspected throughout their useful life.

Most of the inspections done to an aircraft are visual inspections. During heavy maintenance work, much of the interior of the aircraft is stripped out so inspectors can look for damage on the inside surface of the fuselage. Aircraft suffer many types of structural deterioration including corrosion, fatigue, fabrication defects, operation and maintenance, and unforeseen loading. In aircraft maintenance, it is critical to inspect surfaces for any damage that may exist in order to determine the extent of repair work needed, whether that occurs as the result of manufacturing or while the aircraft is in service.

Non Destructive Testing Applications in Aerospace

 

Non-destructive testing (NDT) is one of the quick and most economical ways to perform inspections in Scheduled maintenance and the only way to discover defects that are not visible to the naked eye.

NDT Methods Used in the Aerospace Industry

Several types of non destructive testing methods like liquid penetrant testing, ultrasonic testing, magnetic particle testing and eddy current testing are used to test airplanes.

Liquid Penetrant Testing (LPT)

To reveal the cracks on the surface of airplane, Liquid penetrant testing is one of the most commonly used method in NDT in aerospace industry.

  • “The fundamental purpose of penetrant testing is to increase the visible contrast between a discontinuity and its background,” said a report on NDT techniques used in the aerospace industry.
  • Structural damages or surface defects of aircraft materials were observed with LPT. Fluorescent penetrants are used in critical areas for more sensitive evaluation.

Ultrasonic Testing (UT)

The most common sub-surface inspection technique, ultrasonic NDT uses high-frequency sound waves to locate defects under the surface.UT has many uses in the aerospace industry including detection of:

  • Surface and subsurface defects in welds;
  • Main structural fittings of landing gear legs and engine attachments;
  • Aircraft structure joints and pylons;
  • Bolts located in critical areas;
  • Adhesive bond quality of lap joints and composite structure;
  • Thickness measurement after damage or corrosion removal

 

Magnetic Particle Testing (MPT)

  • In magnetic particle testing, fine particles are applied to the surface to monitor magnetic flux. If damage exists, flux “leaks” from the item’s surface, attracting particles to the area.
  • In the aircraft, MPT is conducted on engines, pumps, landing gear, gearboxes, shafts, and shock struts. It is also widely used for bolt inspection.
  • Obviously, this task requires trained professionals who are capable of performing a variety of different NDT techniques to get a complete and accurate status of the airplane.

Eddy current Testing (ECT)

In any aerospace maintenance and repair organization Eddy current testing plays an important role.

  • Eddy current testing is used in Surface Crack Detection on Aluminum alloys
  • Intersect the inner surface of holes in the component to be inspected.
  • Automated Inspection of Aircraft Wheels / Wheel Hub / Rotor Disc
  • Subsurface Corrosion Detection

There is no question that the success of the airplane industry is dependent on NDT. Without NDT, the cost of maintaining and flying in airplanes would increase dramatically, while the safety of flying would decrease. When people step into an airplane they trust that it will get them to their destination with as little turbulence as possible. NDT plays a vital role in keeping air travel one of the safest modes of transportation.

 


Advanced Nondestructive Testing solutions provide a number of (NDT) services, such as phased array, corrosion mapping, and long range ultrasonics, time of flight diffraction; high-temperature hydrogen attack detection of hydrogen induced cracking along with tube inspection and alternating current field measurement or ACFM.

The Complete Set of Advanced Nondestructive Testing Services

The advanced set of nondestructive services is as follows. This kind of courses are taught in reputed Indian NDT institutes and are an integral part of NDT courses.

Phased array for scanning material strength and thickness

Ultrasonic phased array applications are found in many industrial areas, storing a full record of inspection like A-Scan, B-Scan, C-Scan and S-Scan visual displays that help devise a simple way of understanding the type of flaw and its dimensions.

The phased array differs from standard manual ultrasonic techniques in its ability to examine and analyse large volumes of materials and welds from one location thus helping the inspection of geometries that would prove to be difficult otherwise.

Additionally, it can be used alongside manual encoded scanning devices. This versatile technique means that it can be used in large applications which range from piping and butt welds in vessels to the flanges and sweeps lets.

Time of flight diffraction in offshore applications

TOFD or Time of flight diffraction is a technique that measures and identifies the locations of structural flaws. It is different from the usual pulse echo ultrasonics as it is based on diffracted energy instead of reflected energy.

It is also dependant on time-based, low-energy diffracted signals, which can be received from the tips of flaws in materials. This helps to determine the exact size and position of the flaw which needs to be accurately imaged and measured.

Because this method is not reliant on amplitude, unlike standard ultrasonics, it is also unaffected by restrictions which include the law orientation, uneven or changing material surfaces, or poor couplings and probe location.

Corrosion mapping of offshore equipment

The condition of equipment can be analysed properly with the help of automated ultrasonic imaging systems.

The process is the best way to accurately test the thickness of walls in the piping and large areas of vessels while the system continues to operate minus the high costs of a shutdown. On a standard working day, around 30m² can be inspected.

In-situ metallographic services and replication

In-situ metallurgy evaluation helps perform a comprehensive assessment of the microstructure of components. The process is often known as the field replication of metals and can find out about the overall strength and durability of the materials.

This non-destructive method of inspecting also helps discover any kind of defects, cracking or anything which compromises with the material’s integrity.

Tube inspection services

This kind of tube inspection specialises in eddy current and ultrasonic techniques for both ferrous and non-ferrous tubing. The techniques include a number of technologies such as eddy current testing (ECT, non-ferrous tubing); remote field technology (RFT, ferrous tubing); internal rotary inspection system or IRIS, ultrasonic testing all materials.

By minimising sudden failures at power plants, a large number of scheduled shutdowns can be averted and operations can remain uninterrupted.

These are some of the advanced tube inspection services you should certainly know about.


The advantage of nondestructive testing methods over other destructive methods is that NDT tests the mechanical and other properties without bringing any damage to the subject, which not only saves time but also money during product evaluation.
There are nine methods of nondestructive material testing which are taught during the course of NDT training.

1. Radiographic Testing (RT)

The Radiographic testing is used to inspect the assembled components and find out the imperfections in complex structures.
It uses high-energy photons to inspect materials and look for hidden flaws. In neutron radiographic, the photons are replaced by neutrons.

2. Ultrasonic Testing (UT)

The Ultrasonic testing is used to detect defects in materials that have smooth surfaces. Ultrasonic testing uses a transducer which is connected to a diagnostic machine. This then sends sound waves or vibrations into the material, which needs to be inspected.

3. Magnetic Particle Inspection (MPI)

Magnetic particle inspection comes useful when the material needed to be inspected is located outdoors and at remote locations. This helps detect defects on the surface and the subsurface. It utilizes the concept of magnetic flux leakage.

4. Dye Penetrant Inspection (DPI)

Dye penetrant inspection is sometimes used to detect some faults in the welding surface, casting and forging. There are several defects, this test is able to detect, they are leaks, hairline fractures, and fatigue cracks.This particular method is based on the concept of capillary action, caused by intermolecular forces.

5. Eddy Current Testing (ECT)

The Eddy current testing can detect surface and subsurface defects in parts made up of conductive material. The concept is based on electromagnetic induction.

6. Thermographic Inspection (TI)

Thermographic inspection can find cracks, cavities, voids and other defects found in shafts, pipes and other plastic and metal parts. Thermographic inspection uses still cameras or infrared videos to spot the radiation in the infrared spectrum and this helps create images of thermal patterns on the surface of the object.

Usually, two approaches are used to carry out thermographic inspection: Passive inspection and active inspection.
Passive inspection uses features of interest which are not of the same temperature as the back ground, either it is higher or it is lower than the background.

Active inspection: The energy source is needed to produce a thermal contrast between the background and the features of interest.

7. Leak Testing (LT)

Leak testing is a method utilized to find faults in a variety of fluid systems so that necessary action may be taken to fix it.
Leaks can generate flow only when there is a pressure flow, which flows from higher to lower pressures. Two methods are used to detect flow, Pressure Decay and mass overflow.

8. Guided Wave Testing (GWT)

The Guided wave testing is particularly useful in inspecting pipelines along with metal plate structures, train tracks, and rods. It is an effective test as it can inspect up to 100m from a single location. The long-range ultrasonic testing is sometimes confused with the guided wave testing but they are not one or the same thing and are fundamentally different.

9. Visual Testing/Inspection (VT)

Visual inspection is one of the most basic methods of nondestructive testing, also one of the oldest, however, it cannot be undermined as it is a powerful test. Visual testing is usually used to detect surface flaws and this kind of testing can also inspect various equipment and structures. The other forms of flaw detection have to undergo visual testing. Visual testing can also be enhanced by magnetic particle inspection and dye penetrant inspection.These are some of the important nondestructive testing methods which form the backbone of NDT.


Non-destructive testing (NDT) is the process that involves three processes, namely the process of inspecting, testing, or evaluating. NDT evaluates materials, components or assemblies to find out about the flaws or differences in characteristics that disable the smooth operation of the part or system. That means when the part is successfully evaluated and passes through flying colors that part of the machinery can still be used.

NDT over Other Destructive Testing

If you compare with another kind of tests, like tests, which are destructive in nature and hence to be done on a limited number of samples, rather than working on the materials, components or assemblies, while they are being used.

The destructive tests are utilized to find out the various physical properties of materials which include the ductility, impact resistance, yield and the tensile strength, find out about the fracture toughness and also the fatigue strength.

But the difference between the destructive and nondestructive kind of testing is NDT testing is more about finding out about the differences and discontinuities in the material characteristics.

The nondestructive tests are nowadays, used in a variety of areas like in-service inspections, fabrications, and manufacturing that not only helps control manufacturing processes but also lowers production costs which can maintain the quality level with ease.

During the construction phase, NDT helps overview the quality of materials and also maintain it, but can aid in some of the processes like during the fabrication and also erection phases. The in-service NDT inspectors inspect the products in use and evaluate it to find out about the integrity which is necessary to maintain their usefulness and their integrity.

It is true that nondestructive testing is also used in the medical field too, but the term “nondestructive testing” is usually not used to describe the medical applications.

NDT Test- The Methods Utilised

Different types of penetrating medium or the equipment which is used to perform that test are denoted different method names.

The different types of NDT methods used currently are,

  • Acoustic Emission Testing (AE),
  • Ground Penetrating Radar (GPR)
  • Electromagnetic Testing (ET),
  • Ground Penetrating Radar (GPR),
  • Guided Wave Testing (GW),
  • Microwave Testing (MT)
  • Liquid Penetrant Testing (PT)
  • Laser Testing Methods (LM)
  • Leak Testing (LT)

  • Radiographic Testing (RT)
  • Ultrasonic Testing (UT)
  • Neutron Radiographic Testing,
  • Magnetic Flux Leakage (MFL),
  • Thermal/Infrared Testing (IR)
  •  Visual Testing (VT).

Non-destructive testing professionals use their wide range of expertise in various fields like creative skills, technological and reasoning, to evaluate the materials, structures, and equipment.

The NDT testing professionals bank upon various reliable methods to find the imperfections and find innovative methods which can develop new technology to bring about vast improvements in the field.

Non-destructive testing specialists gather information from different sources regarding the materials in question. This accumulated information is used to decide whether there are any defects in the materials and then to make a decision whether there are proper regulations and standards were maintained when building the equipment and structures.

NDT laboratories cater to various industries which include civil, forensic, mechanical, systems, electrical, aerospace and aeronautical engineering, and also medical applications. The two terms nondestructive inspection (NDI) and Nondestructive evaluation (NDE) are often referred to when describing the nondestructive testing methodology.


Non-destructive testing (NDT) is a procedure which is a combination of analysis techniques that is used to find out more about the properties of a number of materials, parts, products, welds, or systems without causing any harm to the integrity of the unit while undergoing the test.

NDT laboratories are a great help for a number of industries that includes civil, forensic, mechanical, electrical, systems, aerospace and aeronautical engineering, and even various medical applications.

The two terms namely NDI, non-destructive inspection and NDE or Non-destructive evaluation can help describe the various testing methodology of non-destructive testing.

The Different Kind of NDT Techniques or Inspection

There are various conventional methods of training techniques that have over the year have changed and developed a lot and have become well-documented with different codes, standards, and best practices.  The setup of a conventional technique is rather simple in comparison to advanced methods. Some of the testing methods are as follows,

The Conventional Techniques

  • Acoustic Emission Testing or AET
  • Leak testing or LT
  • Infrared Testing or IR
  • Electromagnetic testing or ET
  • Liquid Penetrant Testing or LPT
  • Magnetic Particle Testing or MPT
  • Radiographic Testing or RT
  • Ultrasonic Testing or UT
  • Film Radiography or FR
  • Vibration Analysis or VA
  • Visual Inspection or VI
  • Straight Beam

Advanced NDT Techniques

Advanced  methods are slightly more difficult to understand as they are emerging technologies and may have certain limitations as they lack technician qualification criteria and no industry codification.

As far as advanced techniques are concerned, only an expert technician can interpret the data, understand the setup and hence cater to such advanced NDT techniques.

Also, there are some methods, which can be further broken down into both conventional and advanced techniques. Like if you consider two forms of ultrasonic testing, for example, straight beam ultrasonic testing (UT) which is a conventional technique used in simple applications and then there is phased array ultrasonic testing (PAUT) which can be regarded as an advanced UT technique.

Advantages of Non-destructive Training over Destructive Training

There is no doubt that NDT boasts of a myriad of advantages over destructive testing. We must first focus on the testing equipment of NDT testing which is often portable and can be performed more than once on a single component.

The component can then be evaluated minutely both externally and internally for any kind of flaws which may prove to be detrimental to the component.

The only disadvantage of NDT is that the results are more qualitative and can be repeated and interpreted differently with varying results by various inspectors.

 The Various Industry Applications of NDT

NDT inspections are a part of a number of industries and that includes the oil and gas and petrochemical industries, along with other industries such as automotive, chemicals, aerospace, and defense. So, the only way to detect and reduce flaws is by including NDT tests.

Some Considerations before Undergoing an NDT Testing

When you plan an NDT inspection, there are four considerations that you must keep in mind,

  • The different types of damage mechanism which has to be inspected for.
  • The orientation of the defect along with the shape and size of the flaw.
  • The location of the defect and whether it is external or internal.
  • The various limitations of the NDT method

Having considered the above factors the operators can optimize the production of facilities and increase both personnel and environmental safety.


Industrial procedures like welding or molding undergo a casting process to give shape to many products which include bars, tubes, pipes, metal parts, wires, and so on.

The solid objects often run the risk of breaking in service and it is difficult to either weld or mold them instantly.

It may take long hours to rectify the same and give them the desired shape again or it may be difficult to re-shape them again.

Non-destructive testing is thus employed during the manufacturing process to slash down the risk factor. This enables durability and long lasting capacity of the product. A huge number of equipment are used in different sectors to ensure that quality of the products is not disrupted and the production moves ahead with clock-work precision.

How NDT is able to fix Disorders in Industrial Products

You can find weld defects in metal objects because the weld does not fuse to the metal including porous bubbles inside the weld.

This is a risky situation and may cause the structure to break or a pipeline to crack. These are some of the important examples about how non-destructive testing can prevent damage and minimize the intensity of the damage.

Some of the Industrial products like bars, tubes, pipes, steel structural, pressure vessels, and machine parts can all get damaged during their service lives.

There is the incredible scope of non-destructive testing which covers power plants, automotive parts, aviation/aerospace frames, maintenance of bridges, construction, pipelines, railways, amusement park rides, submarines, medical imaging applications, naval warships, and the list does not stop here.  NDT helps checks the products not only in the fabrication process but also during the service period.

Non-Destructive Testing Equipment

Manufacturers and end users detect the malfunctions early with the help of relevant non-destructive testing equipment. Otherwise, the cost of the damage becomes really high.

The quality of the non-destructive testing equipment is really important so it is bought online or procured straight from the stores.

You should get the testing equipment from the select vendors, suppliers or manufacturers who have earned themselves a reputation in the market.

The raw materials used for manufacturing industrial components are ferrous and non-ferrous metals, polymers, composites, and ceramics.

There can be unmitigated damages to non-destructive equipment if they are not used in the way and at the right time such as corrosion, erosion, corrosion cracking, cracks in welds, breakage and so on.

Non-destructive testing equipment can also detect myriad of faults like detecting surface, subsurface, variations, and internal defects, physical and metallurgical conditions like the structure, hardness and so on that is why the importance of non-destructive testing equipment cannot be stressed enough.

Besides all the above, there are various methods and techniques involved in non-destructive testing which should be kept in mind and all of them are based on scientific principles.

The techniques and methods used for this equipment are liquid penetrant testing, ultrasonic testing, radiographic testing, laser testing, electromagnetic testing, and acoustic emission testing, positive material identification, magnetic resonance imaging, leak detection and so much more.

The most important benefit of non-destructive testing is certainly peace of mind.

Just the fact that the equipment is functioning the way it should be and you are able to avert future accidents, can make you heave a huge sigh of relief.

This is the exact reason the importance of non-destructive testing cannot be undermined and there are more and more training institutes mushrooming across the country, like the NDT training in Vijayawada or NDT Institute in Vizag. Given its importance in the present situation, the future of non-destructive testing seems really bright. Are you willing to give it a try?

 

 


Nondestructive testing (NDT) is an amalgamation of analysis techniques utilized in science and technology industry. These techniques evaluate the properties of a material, component or system without having any adverse effect on the material.

If you want to use your mind and hands in a dynamic industry, NDT is just the course for you. The demand for certified NDT technicians is rising every day. The high demand and low supply of technicians have significantly helped in mushrooming of NDT Institutes.

Why choose to be in the Field of NDT Testing?

Choosing to be an NDT technician is a very important career move! An NDT Technician helps to protect people and industries from various defects, which may lead on to potential problems.

NDT has a great impact on everyday life and assures safety and reliability. A few examples which are found in aircraft, spacecraft (shuttle), pipelines, motor vehicles, trains, bridges,  power stations, buildings, refineries, and oil platforms, which are inspected with the help of NDT.

How to become an NDT Technician

NDT Training is an important training ground for whoever is trying to find a footing in the NDT industry. NDT training is usually provided to students in parts.

For the uninitiated, there is a 40h course that must be undertaken, which can be undertaken in a class or even online.

Once the classroom training is undertaken the next step is the ‘practical’ training. When you are employed by an employer you are hired by an employer as an intern to learn the ropes of NDT training for a few hundred hours to get used to the particular instruments.

Non-destructive is a kind of testing which is used to evaluate materials and components in a way that can examine the materials without affecting their utility. NDT or NDE is used to find the size and location of the defects.

ndt course in hyderabad

NDT plays an important role in everyday life and is necessary to assure quality control. Some of the places where safety and quality control measures are used are the following aircraft, spacecraft (shuttle), motor vehicles, bridges, pipelines, trains, refineries, power stations; buildings and oil platforms, which go through a thorough inspection with the help of NDT.

NDT needs to be used in the correct way to get the results you want, it is also known as the Quality Assurance management tool. NDT is not only about quality assurance but it includes a whole gamut of methods that includes capabilities and limitations, knowledge of the relevant standards and the requirements for performing the tests.

Materials, products, and equipment which do not undergo quality check and the defects are not be discovered at the right time and may need an expensive repair and also have to be replaced much early than its span of life. In such a scenario a loss of revenues is inevitable and may finally lead to an unplanned plant shutdown.

How is the NDT Techniques Applied?

An item construction will need Non-destructive testing at each and every stage. NDT is used to test all the materials and welds and on the basis of that it is accepted, rejected or repaired. The components are then monitored to test its integrity with the help of NDT techniques.

Check out the reasons why NDT is used

  • To reduce cost and reduce the incidences of accidents
  • To improve the quality of the product
  • To provide more information on the repairing done on the product
