Techniques Used in Nondestructive Testing


Non-destructive testing is an efficient method used for detecting the flaws in the various materials used in industrial machinery.  It has become an essential part of all industries particularly the manufacturing sector.  Various nondestructive testing methods are used by manufacturers to find out the defects.  They will then be able to take corrective measures to minimize the cost that would otherwise be incurred if some machinery fails due to some fault in the machine or component.

Ultrasonic testing is used to detect flaws and corrosion.  You can also measure the thickness of products using this method.  The test can be done by using either the tank crawlers or the near drum scanners.  The fields, where this method is mainly applied, is the aerospace and the pipeline industry.  For you to determine the interior fabric of a product, you have to pass an ultrasonic wave through it and then examine the reflected wave.

Non Destructive Testing is used in the detection of the welds and turbine blades, pipelines and some engine components.  For this process to be successful, you have to use tools such as the alternating current field measurement and portable yoke.  It is applied to detect the corrosion in steel pipelines.  For this to happen, the pipelines have to be magnetized.  Lack of flux lines is an indicator that the metal has rusted.

To know whether there are any defects on the surface of products, you should apply liquid penetrate inspection.  Such flaws include weariness, quench or grinding cracks.  Materials such as metal, glass and plastics are the most convenient for this type of test.  Liquid penetrate inspection is an affordable method of surface control.  You can apply this method to nearly all the forms.

The most affordable and the easiest method of Non Destructive Testing inspection is the dye penetrated control.  It is used to test the casting and counterfeiting defects and cracks in a product.  This process is done in a procedure.  You first surface penetrate, penetrate application, excess penetrate removal, developer application, indicator application, inspection, and cleaning.

Non-destructive testing can also be done through visual inspection.  This method is widely used.  Despite its simplicity, a lot of attention should be taken while undertaking it.  Its main application is checking erosion, poor welding, and control protective coating.

How good or how bad material is can be identified through the x-ray method.  It can also be applied to check the imperfection in manufacturing and assembling.  It is simply done by penetrating gamma rays or x-rays through the product.

Machine inspection and checking should be done a common activity among all the industries.  When devices are passed through nondestructive testing, they become more competent.  The flow of the activities in an industry is a function of nondestructive testing.  It prevents wastage of time money and Effort.  It should be adopted by companies that want to carry out their activities without distractions.
