Methods Of Non-destructive Testing To Evaluate The Properties Of Various Materials

Non-destructive testing or commonly known as NDT is a comprehensive collection of

various analyzing techniques that are used in science and industry to calculate the properties of a material, component or system without causing any damage to it. These techniques assure that the material or component being inspected is flawless. Commonly NDT is used in forensic engineering, mechanical engineering, electrical engineering, civil engineering, systems engineering, aeronautical engineering, medicine, and art. NDT methods are used to save time and efforts spent in product evaluation, inspect and repair.

However, every method of NDT should be applied and performed by experts only as every method of Non-destructive testing demands perfection as well as experience. The performance of every method of Non-destructive testing or NDT entirely depends upon the skill, acquaintance, and training of the technician(s). Currently, there are various testing laboratories all over the world that offer best services to cater to your needs and requirements.

Almost every testing laboratory proffers all possible method of Non-destructive testing that includes liquid penetrant testing, bend testing, radiographic testing, remote visual inspection (RVI), magnaflux, eddy-current testing, magnetic particle testing and low coherence interferometry etc. Lets briefly discuss over some of the important Non-destructive methods:

Liquid penetrant testing In this method of Non-destructive testing, a chemical known as Penetrant is applied on non-magnetic/ non-porous materials to identify any surface breaking defects.

Bend testing This particular method is used to measure the bending level /flexibility of material on given strength or force. And its a must for metallurgy industry.

Magnaflux This particular method of Non destructive testing is used especially for transportation industry. However, this method is applied on every metal that is involved in this industry to calculate the integrity level.

MShip hull inspection This inspection is performed to locate any defect in the welds of a ship as well as to characterize them according to size and orientation etc.

Leak Testing This method of NDT is applied to find any leaks at the bottom of tanks or other types of vessels that are especially used in the ship building industry.

Magnetic particle testing Magnetic particle inspection is performed to identify any surface and slightly subsurface flaws in the ferroelectric materials like cobalt, iron and nickel etc.

Radiographic testing - This is one of the major methods of Non destructive testing that is used to inspect various metals to identify the hidden flaws with the help of short wavelength electromagnetic radiation. Browse through http://www.abcndt.com for more information.
