NDT is important in most industries because it is used as a Quality Assurance. The technicians will inspect for errors in welds and stress fractures from manufacturing.
It all depends what method(s), experience, and what level you are. It can be anywhere from about $35,000 - $175,000
They are targeted in the engineering field, What they do is check for flaws/weaknesses in the building structures to make sure their in tip top shape to be in.
The best method for detecting defects in welds is Magnetic Particle. You can also use Fluorescent penatrent, and x-ray but they can be time consuming and often unreliable.
The National Board of Boiler and Pressure Vessel Inspectors interprets and enforces the ANSI / ASME codes within the pressure vessel industry throughout North America. "The National Board" stipulates that all pipe welds must have a pressure leak test applied to each assembly before that particular assembly can be put into service. As per B31.3 of the ASME codes the preferred method of testing the integrity of welds is through application of Hydrostatic pressure. All other NDT testing methods e.g. radiography (X-rays), magnetic particle examination, liquid penetrate examination etc. are considered variances to B31.3. Most vessels, flanges, valves and other various pipe assemblies are tested at the manufacturer's facility; the only portion of an assembly that remains untested is the weld (tie-in point) which connects the various assemblies under field conditions. In other instances a leaking flange may require replacement as part of an on-going maintenance program (between turnarounds) creating the need to isolate and hydro-test the connecting weld. It is to these specific areas of the pipe assembly that CAR-BER has focused attention. Traditionally the method of testing welds which connect assemblies in the field involves filling the entire system with testing medium and pressurizing to a pre-determined value (usually 1 1/2 times the working pressure) and maintaining that specific pressure for a pre-determined time. Such a methodology requires extensive person-hours to blank and purge the entire assembly and requires large amounts of medium to perform the test. The requirement for large amounts of medium means that a significant amount of medium must be lost in order to register a noticeable change in pressure. The minuscule amounts of medium required for the CAR-BER equipment to perform, translates to very precise pressure readings should the slightest volume of medium escape the pressurized vessel during testing procedures
LPI Media was created in 1997.

API = American Petroluem Institute NDT = Non-destructive Testing NDT is a process of testing the integrity of a piece of pipe (oil well tubing or casing) that does not damage the material in any way. There is wide range of ways to perform NDT evaluations on tubing and casing products.
LPI Stands for "Lines per inch". The number of lines printed in a Vertical inch. The offset Printing lines per inch in a halftone or line screen. LPI is a measure of the fineness or the coarseness of the screening in photographs and tints in a printed piece.
No.
Qualifications needed to enter into an NDT job varies greatly depending on the job being taken up. This may include having experience of running NDT operations, FPI qualifications or other NDT certification.

IEQS group is the best NDT institute in Chennai. This was the best institute for learn this type of courses they are really talented to make the student knowledge very well and also they are offering so many courses to conduct. NDT stands for NON DESTRUCTIVE TESTING course.

A guided wave ndt equipment is that equipment used to perform Guided Wave Nondestructive Testing. Most equipments are based on piezoelectric or magnetostrictive collars.
Answer If you have an engineering degree, you could probably get a job as a NDT inspector or accident investigator. NTSB offers a course in accident investigation. They take you to a simulated crash and you practise reading the signs. The FAA and NTSB probably have other classes on NDT inspection such as borescope and eddy current inspections.
