Non Destructive Testing Methods - How Eddy Current and Ultrasonic Testing Works

Nondestructive testing (NDT), sometimes called nondestructive examination (NDE) or nondestructive inspection (NDI), is any method of materials testing whereby the material being tested is not damaged or destroyed. It is important in quality control as well as useful in research. It is also a key element in material inspection systems. Nondestructive testing, using ASNT standards, can be used to for bolt hole scanning, crack detection, flaw detection, pin hole detection, conductivity testing, thickness measurement, and corrosion detection. Two reliable nondestructive testing solutions are ultrasonic testing (UT) and eddy current testing.

Non Destructive Testing Basics

Nondestructive material testing with ultrasonics is more than 40 years old. From the very first examinations, using ultrasonic oscillations for detection of flaws in different materials, it has become a classical test method based on measurements with due regard to all the important influencing factors. Today it is expected that ultrasonic testing, supported by great advances in instrument technology, give reproducible test results within narrow tolerances.

Efficient Methods of Non Destructive Testing

Non Destructive Testing (NDT) with its efficiency to detect flaws in the various materials used in industrial machinery has made it an essential part of all industries more particularly, manufacturing. Nowadays industrial organizations make use of various NDT methods to find out the defects and then take corrective action to minimize the cost that would otherwise be incurred if some machinery fails due to some fault in the material or component.

Non Destructive Testing (NDT) and Destructive Testing

Non Destructive Testing and Destructive testing have found much use in various industries like manufacturing, construction, automotive, aviation, railways as well as many engineering disciplines to check the conditions of various materials, components or systems. In this article we will discuss some of the Non Destructive and Destructive Testing methods and their applications.

Non-Destructive Testing Choosing the Right Inspector

No one has a perfect organization but it does not mean that one should not try to make it perfect. If you are also having an organization that deals in heavy equipment like space or medical equipment then you should try to see to it that all the equipment you are offering to your clients are made up in accordance with the highest quality standards. You should also try to explain the need of getting these equipment inspected to the people or organizations who have bought these products from you.

Going through Non-Destructive Testing

Surviving in this competitive world is not an easy task, a company has to face a lot of complications that can pose hindrances in its work but still it is vital for a company to keep trying to be successful no matter how worst the situation is. If you are also an owner of a company that is facing tough competition in the market then you must try to enhance your product quality to satisfy more and more customers and thus should extend your customer's base up to a much higher level than ever before.

Choose for the best Non Destructive testing for the safety of your company

NDT can be described as a set of methods and techniques used to inspect the integrity of materials. Perhaps, its most crucial point is NDT inspects materials without degrading them in any way or make it non destructive. Within the industry the use of NDT is to maintain the integrity of essential pieces of mechanical equipment to provide safety, also to prevent unexpected downtime and loss of revenue in the industry.

Due to the benefits, safety critical and high turnover; industries tend to take advantage of NDT also known as Non-Destructive Testing more than anything else. Examples of such Industries are power, chemical, and petroleum industry. There are so many routes into the NDT industry; one of the methods is engineering at the degree level. After that there are specific certifications such as API 653

Methods of Non Destructive Testing

Non destructive testing means the methods or techniques that are used to check or examine the properties of objects, materials or systems without any destruction. It is a process that saves time and cost for research, evaluation and troubleshooting of products. There are many non destructive testing methods such as low coherence interferometers, eddy current testing, radiographic, magnetic particle, ultrasonic, liquid penetrate, remote visual inspection etc.

Why Non destructive testing is so important?

There are various methods used in non destructive testing for identifying the flaws and damage which is essential for any industrial plant inspection. In non destructive testing all the tests are carried out without altering any material. Experts will not cut or scratch the surface to carry out this type of test successfully. There are many types of NDT without altering the materials in any way. Such tests are vital when the aesthetic appearance is important.

In other occurrences when there are hazardous materials in question this test can provide a good solution. Non destructive testing is generally a part of the industrial maintenance work which ensures that the plant is in good working condition. Results of this test ensure whether the plant should temporarily suspend operations or there is need for complete overhaul.

Pipeline Welding

Pipeline welding is a process that must be executed with precision. 

Lives and investments must be protected from any kind of leakage or accident that any activity involving oil or natural gas is prone to produce. Because these fuels are highly flammable and toxic to our health, the joints must be welded within strict governmental specifications. 

Thankfully, pipeline companies, western pipeline corporation included, are dedicated to the safety and efficiency of their pipelines to ensure safety.
