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.
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.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

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
