The Four Most Important Benefits of The Different Types of NDT Testing Methods

Nondestructive testing or testing without damaging the product that is tested has been a great deal longer than anyone can even think of. Actually, the earliest NDT testingvisual testing, is as old as the human race itself. The subsequent oldest NDT testing methods sprang up in 1895 when the German physicist Wilhelm Conrad Rontgen initially invented the X-ray. After a century, NDT methods have turned out to be much more vigorous. They currently include magnetic particle testing, liquid penetrant testing, ultrasonic testing and visual inspection.

So you can envisage, the advantages of non destructive testing have enhanced over time. Here are 4 explanations why non-destructive testing is valuable.

  1. Safe

Non destructive testing methods are carried out to find out whether an element is endangered or in want of fixing. The majority of the tests are totally safe to humans, and all checks leave the products tested wholly unimpaired. in addition, in industries with unstable or high-stress tools and machinery, NDT as a precautionary measure preserves lives.

  1. Reliable

With regard to getting exact results, nondestructive evaluation (NDE) and nondestructive inspection (NDI) is dependable due to the assortment of obtainable and balancing alternatives. Any piece of tools or machinery can be subjected to a number of nondestructive tests, which removes the danger of failure to notice or factual error.

  1. Affordable

Different industries have their own different safety criterion, and all kinds of machinery need to be frequently scrutinized at different periods. But regardless of what has to be scrutinized, a nondestructive test will forever be the most reasonable alternative. NDT inspection techniques like car crash tests normally cost a bit more. moreover, non-destructive evaluation or even non-destructive inspection can effect in insights that contribute to the substitution or mending of tools before breakdown can happen.

  1. Peacefulness

The ultimate advantage of NDT techniques may be tough to enumerate, but it’s vital of all. When equipment function in order and future accidents can be avoided with effortless tests adds years to the existence of a stressed project manager. Plus when employees are aware that they are safe, the productivity of work productivity automatically increases.

NDT or Non Destructive Testing is broadly applied in several industries to verify the reliability of materials devoid of any damage to the testing material. In this process, it is assured that the product on which nondestructive testing is executed is not tainted in any manner. This procedure aids in securing the security and quality of the automatic tools so as to avert unanticipated downtime and revenue loss in the business. Quite a lot of industries like aeronautical, mechanical, electrical, civil engineering, nuclear as well as medicine carry out non-destructive testing to guarantee quality control. It is performed with the assistance of different techniques like magnetic particle testing, ultrasonic testing, liquid penetrant testing, visual testing etc.

Generally, NDT entails three kinds of testing processes namely magnetic particle inspection, PT, and visual inspection. Liquid penetrant testing level 1 is an examining technique mostly executed on materials that are non-porous for instance ceramics, plastics and metals to identify defects on the surface, which either may or may not be noticeable to the naked eye. Prior to carrying on this test, the part to be tested must be comprehensively cleaned and then a high penetrating power liquid is applied so that it penetrates the surface gap of the discontinuity of the part. Subsequently, surplus penetrant is got rid of and a developer material is used that absorbs the liquid from the supposed imperfection to disclose the separation. The surmised imperfection becomes visible due to a color contrast in usually visible light or by fluorescence in dark ultraviolet light. So, liquid penetrant inspection is executed to augment the perceptible contrast between a separation and its milieu in a material.

Penetrant testing is executed by experienced pros who have undertaken scrupulous training  ahead of them being hired to carry out the job. It is also a must that they possess liquid penetrant inspection certification when they perform non-destructive inspection or non-destructive evaluation. Also, a variety of courses is accessible which can assist you to study more concerning this particular method and provide you with the needed knowledge in detecting defects in different products. Once you attend a course plus take up appropriate training, you will achieve an acknowledged NDT certification which will aid you to get jobs in a variety of industries.

Now, a lot of the companies offer liquid penetrant training in Houston and you can find them by visiting their particular websites. Besides the training academic sessions, you can as well register for dye penetrant testing classes in conducted by TXNDT Academy in their joint NDT courses in Houston TX so that you can know more about the nuances of this method.

TXNDT the Top NDT Academy for Getting Trained in Magnetic Particle Testing Methods

Magnetic Particle Testing MT, a very old but and most dependable NDT testing methods, is repeatedly not afforded the credit it warrants. It is viewed as a ‘non-alluring’ nonetheless essential procedure in the area of materials examining. And even as there are important variables that ought to be looked at, the modus operandi for achieving the magnetic particle inspection, it is a comparatively simple and reliable method—if it is carried out with competent personnel who have undergone magnetic particle inspection training and also hold a magnetic particle inspection certification, by qualified process and appropriate equipment. And nevertheless, with its proportional effortlessness, mistreatments still happen.

In theory, magnetic particle testing methods is a comparatively uncomplicated concept. It can be regarded as a combo of two nondestructive testing techniques: magnetic fluctuation leak testing as well as visual testing.

In an example of a bar magnet if it is merely fractured but not broken fully in two, a north as well as the South Pole will shape at each rim of the fracture. The magnetic field extends when it meets the tiny air hole shaped by the crack as the air cannot hold up the same amount of magnetic field per unit volume as the magnet itself can. When the field broadens out, it emerges to seep out of the material and, consequently is called a fluctuation leakage field. If iron particles are scattered on a fractured magnet, the elements will be attracted to and collect at the poles, at the edges of the magnet, also at the poles at the borders of the fracture. This bunch of particles is much easier to notice than the real crack and this is the basis for magnetic particle testing.

Therefore the first rung in MT testing is to magnetize the component that is to be scrutinized.

As a professional field, NDT testing, NDT inspection, and NDT techniques extend many chances, and there is a huge demand for skilled workers trained in the non-destructive inspection. TXNDT is one such place where you can join the different NDT courses and NDT classes so that you can also take off in your career with magnetic particle NDT. Once you complete the course  you can go in for NDT certification courses or non destructive testing certification or maybe NDT level 1 certification. This nondestructive testing certification will help you a lot to join companies as NDT level 1 or NDT level 3 technicians, which is, in fact, the humble beginning of your career.

Magnetic Particle Testing the Best NDT Method to Start Off Your Career

Magnetic particle inspection effectively identifies surface as well as near-surface imperfections in ferromagnetic substances like steel and iron. This is merely one of a few kinds of nondestructive testing techniques and is so named since the materials plus products are examined or scrutinized without equipment casualty.

The procedure

Magnetic particle testing is executed by spreading fine magnetic specks on the surface of a trial object since it is being magnetized, inducing a buildup of specks at a separation, for instance, a break, lap, enclosure or closure. These specks have lofty magnetic porous, so they are without difficulty magnetized as well as pulled towards tiny magnetic seepage areas induced by the separations.

Application of the particles during magnetic particle testing, can be either as:
• Dry as fine particles or
• Wet as a suspension system in a petroleum-base or water-based transporter

Dry particles are generally utilized for ease in field MT testing. The fluorescent soggy examination is regarded best for discovering minute discontinuities since much smaller specks are applied plus the liquid transporter lets the particles to run effortlessly to small seepage fields to shape signals. A wet magnetic particle inspection has a benefit over a dry examination as the tools used in this procedure can rapidly and effortlessly scatter a uniform coating of corpuscles on the exterior of the substance or element to be tested.

The magnetic field is produced either by DC circuits or by AC circuits. AC circuits are effective in detecting surface cracks while DC circuits help in finding discontinuities under the surface.

Magnetic particle NDT can be employed to untreated materials, elements or products throughout different stages in the production process as well as during tools or equipment preservation and on the whole to locate weakness cracks. In case you are also looking to take up a career in this field then getting a magnetic particle, inspection certification becomes a must for you.

Magnetic particle testing or MT testing is a type of NDT techniques for non-destructive trying that helps in detecting all the defects on or close to the outside of the matter that is being tested. This type of testing is intended for any objects capable of being magnetized and is normally utilized in automotive as well as aerospace industries  to check engine elements for leaks or fractures. The procedure consists of cleaning and applying dyed iron particles to the matter. Then, the matter is magnetized by means of a magnet or by passing electrical current. The iron specks will pack around any facade or subsurface faults in the object. Level II examiners are authorized to establish and standardize equipment, carry out the examination and assess the outcomes. In some instances, Level II inspectors may as well oversee on-the-job instruction for Level I inspectors. Nondestructive testing certification for examiners is generally done via the organization that employs the examiner or other offices.

Abstract

Nondestructive testing has become an integral part of the process when determining the remaining lifespan of in-service steel utility pole structures and plays an essential role in the manufacturing of new replacement structures.  The nation’s critical utility infrastructure has come to rely on nondestructive testing even more as it ages and the service life of structures is pushed to its limits.  However, with the probability of detection of defects at an alarming low percentage, it is critically important for utility personnel to understand the various methods of nondestructive testing that can be employed and their limitations.  This paper/presentation will discuss the advantages and disadvantages of each method as well as their correct employment in a plant versus a field environment.  And finally, it will attempt to address some key points:

  • What are the appropriate training requirements and certifications necessary to insure that personnel inspecting your steel utility poles know how to perform these tasks correctly?
  • What types of defects should they be looking for?
  • How to properly evaluate findings to ensure critical defects are located.
  • Repairing defects while not doing more harm to the structure.

 

The Critical Role Nondestructive Testing Plays in the

Steel Utility Pole Industry

Introduction

When we flip the light switch, the light turns on 99.9% of the time. As a society, we have generally come to take this for granted.  The electrical grid in the United States consists of an estimated almost 400,000 miles of transmission lines, some of which date back to the 1880’s.[1]  With this aging infrastructure comes a need for forecasting the lifespan of existing utility structures along with the manufacture of utility structures for both new construction and replacement of in-service lines.  Nondestructive testing has become an essential component in the inspection of in-service structures while playing a critical role in the quality control during manufacturing.  As inspections are used to find discontinuities, cracks or other potential damage in a physical structure, it is important to know the strengths and weaknesses of each method of NDT as this will allow a properly trained and certified technician to select the right method to employ and then perform this testing accurately.  Electrical demand will continue to grow over the coming years, and with it, the need for proper Nondestructive Testing in the utility industry will continue to expand as well.

What is NDT?

There are numerous technical definitions of Nondestructive Testing (NDT), yet we feel that its simplest form is by far the best and most concise – NDT allows materials and components to be inspected and assessed without any physical damage to them.

NDT Methods

While the American Society for Nondestructive Testing (ASNT) recognizes nine major methods along with several other subcategories, this presentation will be focusing on the three primary methods used in the inspection and manufacturing of steel utility poles: Magnetic Particle Testing (MT), Ultrasonic Testing (UT) and the often overlooked Visual Testing (VT).

Magnetic Particle Testing (MT)

Magnetic Particle Testing (MT) uses magnetic fields to locate surface and near surface discontinuities in ferromagnetic materials such as steel.  In the steel pole industry, the magnetic field is applied indirectly, most commonly with a yoke.  Once the magnetic field is established, a fine pigmented ferromagnetic powder is applied to the surface of the part, which will be drawn into the magnetic leakage field caused by a discontinuity, causing a visible indication.

Magnetic Particle Testing (MT) Conducted on a Long Seam.

MT equipment is inexpensive to purchase and operate, is portable and it is relatively easy to train personnel in its use. MT does have its downsides as it is only suitable for surface breaking and near surface discontinuities, can only be used on ferromagnetic materials and can be misevaluated without proper training. Proper initial and ongoing training will teach a technician to tell the difference between a relevant indication and a false indication that could lead to hours of re-work during fabrication.

Relevant or Irrelevant Indication? Should this be Repaired?

Ultrasonic Testing (UT)

Ultrasonic Testing (UT) introduces sound waves to the part or item being tested via a transducer made up of a piezoelectric crystal that converts electrical current to sound waves.  The sound traveling through a part hits material with a different acoustical impedance and some of the sound will reflect back, be received by the unit and represented as an indication on the screen.  Knowing the velocity at which sound travels through a part, along with the time of travel results in a distance to the indication.

Ultrasonic Testing (UT) of a Newly Installed Gusset.

Ultrasonic testing is a portable method of inspection, gives consistent results and can detect both surface and subsurface indications. As such it is well suited for weld inspection in both manufacturing and field environments.  While significantly more expensive than MT to train and equip a technician, UT is still cost effective and can provide an extreme level of detail.  UT has significantly higher requirements for both classroom and field training than MT and without proper training, misinterpretation of findings can occur with dire consequences.

Visual Testing

The third method of NDT this paper will discuss is Visual Testing (VT). Visual inspection techniques rely on the aided and/or un-aided eye for the purpose of inspecting a part or weld.  VT is the most common testing method used across all industries as it is inherently part of all other test methods.  VT may be aided by the use of a magnifying glass or un-aided using the naked eye and many defects are able to be located using VT including cracks, corrosion, misalignment of parts and discoloration.

VT can be performed with little or no equipment but still requires training in the analysis of findings and the use of proper procedures.  VT’s limitations include only being able to detect surface breaking flaws and it is less sensitive to smaller flaws than other methods.

Even taking those limitations into account, as long as inspections are being performed, VT will be one of the most important tools an inspector can have in his arsenal.

Nondestructive Testing in a Manufacturing Environment

In any facility producing steel utility structures, NDT should be an integral part of nearly every stage of production.  With the emphasis on cost efficiencies, lower quality steel, and high deposit welding consumables, quality control has the difficult task of keeping all the variables within tolerances.  NDT is one of the key tools in ensuring that a quality product is received in the field by the end user.

UT is used to detect laminations in steel baseplates, to confirm weld penetration on long seams and is crucial for the confirmation of a complete joint penetration (CJP) weld.  UT is required on 100% of structures with large T-Joint welds such as base plates and flanges for the detection of cracks both pre and post galvanizing.[2]  Flaw detection in welding may be the single most important thing UT is used for and due to inconsistencies in training programs, many of those flaws are missed by improperly trained technicians.

MT and VT also aide in weld inspections – the identification of undercut, cold lap, crater cracks and poor starts/stops are just a few examples. Additionally, MT is often used during repairs to confirm that a crack is ground away prior to re-welding.  In many cases multiple methods may be needed to validate an indication or increase the probability of detection for small indications.[3]  This can be seen regularly with the use of visual testing to support all other forms of inspection.

Nondestructive Testing for In-Service Structures

NDT plays an integral role in the continued safe operation of in-service steel utility structures to determine if a structure is fit for continued service or needs to be repaired, strengthened or replaced. It is not uncommon to find a field technician using UT or MT inspection for the detection of fatigue in welds in the form of cracks.  Often located at the top toe of the base plate to pole shaft weld on the bend lines of a multisided pole, what begins as a stress riser, over time, becomes a crack due to cyclic stress on the structure.  In most cases, these toe cracks, cannot be seen by the naked eye and require some form of NDT to detect.

Internal and external corrosion can cause catastrophic problems to in-service utility structures up to and including failure. As seen above, left undetected and unchecked, corrosion can cause wall loss that often leads to a significant decrease in the structural capacity.  Using UT inspection, a corrosion assessment can be completed giving an engineer the information needed to quantify the structural capacity of the effected pole.  Without the use of NDT techniques, estimating a lifespan or plan of action for repair would be a shot in the dark.

Proper Training Is Key

Training programs in the NDT industry are numerous and varied and range in quality from very poor to excellent. ASNT has given us an excellent guideline utilizing SNT-TC-1A as a recommended written practice for the qualification and certification of personnel, but it is only a guideline and some employers choose to provide only the bare minimum to qualify technicians.   It has been estimated that in some sectors the probability of detection is as low as 52% for a surface discontinuity with a length of .1”.[4]  Many variables that lower the detection rate can be eliminated with a high quality training program and a written practice following SNT-TC-1A or CP-189.

The process of qualifying technicians should be performed through formal classroom training with the recommended series of exams to prove knowledge and visual acuity.  In some cases, employers train in-house through the use of a “Corporate Level III” and bad habits can be passed on.[5]  A knowledgeable, properly certified educator using recognized course material is recommended and can prevent an internal “legacy” that utilizes those bad practices.

Following formal training, an apprentice technician needs quality on the job training meeting the minimum number of hours working under the direct supervision of a certified individual.  Once the trainee has met the requirements of his company’s written practice and proven his competency, the company can certify him in method.

Summary

As our countries infrastructure grows and ages, there will be an increased need for ongoing manufacturing quality control programs along with reliable monitoring and assessments of in-service steel utility structures.  As that need grows, so too does the demand for well trained and certified individuals to perform nondestructive testing in the utility industry.

To ensure the continued safe operation of your structures and extend their lifespans, NDT should be an integral part of both you and your pole manufacturer’s daily operations.

Get Trained in Magnetic Particle Testing and Inspection to Take-off Your Career

Magnetic particle testing or MT is a nondestructive testing technique for detecting surface as well as near surface separations in ferromagnetic stuffs. The procedure lays a magnetic field into the element. The part is actually magnetized by either direct or indirect magnetic induction. Direct magnetic induction takes place when an electric current is guided via the test object whereby a magnetic field is created in the object. When a magnetic field is enforced via an external source indirect magnetization occurs on the test object.

The existence of a surface or a subsurface separation in the test object lets the magnetic flux to reveal, since air is not able to withhold the same quantity of magnetic field per unit volume as is done by metals. Now ferrous particles are applied to the section. The particles can be either dry or wet suspension. If a region of flux leakage is found, the particles will automatically be attracted to this region. The molecules will then gather at the region of leakage and shape what is recognized as an indication. The indication will then assessed to find out what it is, what the cause is for this, and what activity should be called for, if required. When you take up a course at NDT academy then you will without any doubt taught all these methods and how you do it will be shown practically to you.

Applications

The major industrial applications of MT testing are ultimate inspection, receiving check, in process scrutiny plus quality control, preservation plus repair in the transport industries, plant as well as machinery preservation and check up of huge constituents.

Magnetic particle inspection training will help you and show you how the cost-effective and relative quicker non-destructive test technique is applied extensively in petrochemical industries, power generation, Locomotive, nuclear, automotive, Aerospace.
Magnetic particle testing methods are a very receptive type of testing technique. It can sense tense operating weariness breaks in revolving parts or sneak fractures on steam piping. Magnetic Particle Inspection cannot be used to test the authenticity of austenitic stainless steels as it is neither non-ferrous nor non-magnetic ferrous material.

Magnetic particle testing training can be taken up at the Texas NDT Academy for that advanced learning. Training in this technique is one of the nucleus parts of TXNDT. If you want a career in MT testing then a magnetic particle inspection certification is a must.

Get Trained in Magnetic Particle Testing To Locate Discontinuities

DSCN8815Non-destructive testing denotes testing techniques which does not source any damage to the matter that is tested. These methods are normally utilized for trying out the exterior or interior issues of an arrangement or equipment or an invention but will not hinder its future functioning or operation.

NDT includes a collection of element testing techniques for evaluating the usability of a portion devoid of any integrity compromise. Nondestructive testing is applied often in critical industries like prostheses, medical instruments, power generation, aerospace, petrochemicals, offshore and marine and oil and gas. Because of the ability of NDI and its assurance of very high degrees of security and quality, NDT has a very important role to play in both OEMs as well as in-service upkeep.

Magnetic Particle Inspection or Testing
There are a variety of techniques that is being applied for these tests. Magnetic Particle Testing is conducted on products or systems done of iron or even steel or for any other products or items having ferromagnetic attributes. Flaws which may be present either on the surface or even subsurface of a material will be visible through this type of testing. Damages in the form of holes or even cracks, which is not visible to naked eyes, can be seen through this type of testing.

Pros and cons of Magnetic Particle Testing
Other than the capacity of the test tools no other relative restrictions are there with regard to the dimensions of the parts to be inspected by the MT method. No far-reaching or complex pre-clean-up of elements is necessary before scrutiny; generally only solvent degreasing is required to get rid of oils, paints, grease, heat-treat scale etc., so as to give the most precise test outcomes. This test can also be done either before or even after plating. It is normal pattern to degauss the parts after the inspection and then clean them so that any magnetic particles that are stuck can be removed.

MT training
MT testing can be used to test raw materials, products or parts during the different stages of the manufacturing course. This test can also be used for tools or equipment maintenance and service to find weariness splits. MT is a specific NDT technique. The magnetic particle testing training offered by TXNDT Academy is superlative. Also the training, examination and magnetic particle inspection training will facilitate you to conduct tests to international criterions. Also if you hold an NDT Certification then job prospects for you is very high.
