ESL technical courses are developed for inspectors, engineers, technologists, designers, supervisors, maintenance, and quality assurance personnel who work for owners-users such as petrochemical plants, refineries, gas plants, power plants, oil/gas pipelines, pulp and paper mills, municipalities, or those who work for engineering procurement companies, inspection companies,and fabricators.
ESL INDUSTRIAL SUPPORT SERVICES , an NDT TRAINING INSTITUTE offer specialised training courses for the inspection of pressure systems and mechanical plant. We are one of the main providers of NDT, WELDING, PAINTING, ASME and API certified inspector preparatory and certification courses. Courses are available for individuals and smaller contractors as well as in-house training tailored to the needs of valuable clients.
To ensure the highest quality ESL NDT TRAINING INSTITUTE, all ESL courses are developed and taught by highly knowledgeable and experienced instructors. ESL training ensures course development, delivery, and evaluation is in accordance with CODES and STANDARDS . We not only teach “what” is in the Code or Standard, but more importantly, “why” it is there.
From welder to inspector, the best way to learn more about a potential career in supervisory and managerial positions is through training and certification. By continuing your education in our ESL NDT TRAINING INSTITUTE , you can discover a dream job that is less physically demanding and increases your earning potential. Increase Your Earning Potential.

NDT TRAINING INSTITUTE
The field of Nondestructive Testing (NDT) is a very broad, interdisciplinary field that plays a critical role in assuring that structural components and systems perform their function in a reliable and cost effective fashion. NDT technicians and engineers define and implement tests that locate and characterize material conditions and flaws that might otherwise cause planes to crash, reactors to fail, trains to derail, pipelines to burst, and a variety of less visible, but equally troubling events. These tests are performed in a manner that does not affect the future usefulness of the object or material. In other words, NDT allows parts and material to be inspected and measured without damaging them. Because it allows inspection without interfering with a product’s final use, NDT provides an excellent balance between quality control and cost-effectiveness. Generally speaking, NDT applies to industrial inspections. The technologies that are used in NDT are similar to those used in the medical industry, but nonliving objects are the subjects of the inspections.
Nondestructive evaluation (NDE) is a term that is often used interchangeably with NDT. However, technically, NDE is used to describe measurements that are more quantitative in nature. For example, an NDE method would not only locate a defect, but it would also be used to measure something about that defect such as its size, shape, and orientation. NDE may be used to determine material properties, such as fracture toughness, formability, and other physical characteristics.
ESL NDT TRAINING INSTITUTE OFFERS FOLLOWING COURSES:
Visual and Optical Testing (VT)
The most basic NDT method is visual examination. Visual examiners follow procedures that range from simply looking at a part to see if surface imperfections are visible, to using computer controlled camera systems to automatically recognize and measure features of a component. In our ESL NDT TRAINING INSTITUTE we provide a theoretical and industrial oriented practical training.
RT involves using penetrating gamma- or X-radiation on materials and products to look for defects or examine internal or hidden features. An X-ray generator or radioactive isotope is used as the source of radiation. Radiation is directed through a part and onto film or other detector. The resulting shadowgraph shows the internal features and soundness of the part. Material thickness and density changes are indicated as lighter or darker areas on the film or detector. The darker areas in the radiograph below represent internal voids in the component.In our ESL NDT TRAINING INSTITUTE we provide a theoretical and industrial oriented practical training.

Magnetic Particle Testing (MT)
This NDT method is accomplished by inducing a magnetic field in a ferromagnetic material and then dusting the surface with iron particles (either dry or suspended in liquid). Surface and near-surface flaws disrupt the flow of the magnetic field within the part and force some of the field to leak out at the surface. Iron particles are attracted and concentrated at sites of the magnetic flux leakages. This produces a visible indication of defect on the surface of the material. The images above demonstrate a component before and after inspection using dry magnetic particles.In our ESL NDT TRAINING INSTITUTE we provide a theoretical and industrial oriented practical training.

Ultrasonic Testing (UT)
In ultrasonic testing, high-frequency sound waves are transmitted into a material to detect imperfections or to locate changes in material properties. The most commonly used ultrasonic testing technique is pulse echo, whereby sound is introduced into a test object and reflections (echoes) from internal imperfections or the part’s geometrical surfaces are returned to a receiver. Below is an example of shear wave weld inspection. Notice the indication extending to the upper limits of the screen. This indication is produced by sound reflected from a defect within the weld.In our ESL NDT TRAINING INSTITUTE we provide a theoretical and industrial oriented practical training.
Penetrant Testing (PT)
With this testing method, the test object is coated with a solution that contains a visible or fluorescent dye. Excess solution is then removed from the surface of the object but is left in surface breaking defects. A developer is then applied to draw the penetrant out of the defects. With fluorescent dyes, ultraviolet light is used to make the bleedout fluoresce brightly, thus allowing imperfections to be readily seen. With visible dyes, a vivid color contrast between the penetrant and developer makes the bleedout easy to see. The red indications in the image represent a defect in this component.In our ESL NDT TRAINING INSTITUTE we provide a theoretical and industrial oriented practical training.

Eddy Current Testing (ET)
There are a number of electromagnetic testing methods but the focus here will be on EDDY current testing. In eddy current testing, electrical currents (eddy currents) are generated in a conductive material by a changing magnetic field. The strength of these eddy currents can be measured. Material defects cause interruptions in the flow of the eddy currents which alert the inspector to the presence of a defect or other change in the material. Eddy currents are also affected by the electrical conductivity and magnetic permeability of a material, which makes it possible to sort some materials based on these properties. The technician in the image is inspecting an aircraft wing for defect.

Leak testing (LT)
Leak testing is also sometimes included in NDT and the methods used vary from simple bubble testing by visual examination, to very sensitive methods using radioactive gases.
The main methods are:
||soap solution – visual
||sound – ultrasonic detector
||hydrogen – Pirani gauge; mass spectrometer
||halogen gas – electron capture gauge
||helium – mass spectrometer
||radioactive gas – pulse counter
The mass spectrometer method with helium and the radioactive gas (Krypton-85) method are the most sensitive, but the latter requires special safety precautions.
Leak testing is widely used on pressure vessels and vacuum systems in situ, or a specimen can be placed inside a gas-filled enclosure and then tested for inward leaks.
