Testing Systems without Destruction


You can stretch a material to a point of breaking to establish its usefulness before use. The method is effective and economical when it is applied on systems which of high volume with low cost.This implies that the technique is not fit for use in in systems of high value.


Furthermore, it will not be insensible owing to the fact that when the material breaks, your knowledge advancement is adversely affected.Alternatively, you can carry out the tests and successfully arrive at a conclusion as the usefulness of the subject material remains intact. It involves probing for any defects in a system prior to its use.


Non-destructive Thermal testing gives confidence that the material being used are defects free and risks of problems in future are avoided.  The method is common with majority of manufacturers more so in the aerospace in industries. Various technologies are used in the application of non-destructive testing owing to the fact that it has proven to be more advantageous.



Top in the list of applications is in visual and optical testing.  It the area of visual and optical technology, visual examiners have succeeded in the application of non-destructive testing. Effects of light and resistance to tension are some of the qualities that are tested in visual and optical aids that are used by man using the technique.Addition, machines such as bioscopes and computer aided cameras are used to examine the qualities and defects in the materials used to manufacture optical and visual items.


The other technology involved that makes use of non-destructive testing is radiography.  The qualities and imperfections of the material in subject are tested by use of X-rays. Just like the way a doctor examines a human body to detect any forms of fractures in bones and any other defects.A radiographer will direct a radiation to the part to be tested through to a digitized device for detection to produce a film for interpretation by the expert.The way it works is that a film is produced which carries information of the status of the elements of the substance once radiations are pointed to the area to be tested via a digitized machine.

Next is ultrasonic testing.The application part of non-destructive testing involves passage of waves with high frequencies through the material subject of the test in order to detect any defects and discontinuities and changes in features.  As sound waves produced in the system a receiver will receive any information about the material being tested.


In magnetic particle the technical of non-destructive testing is the only way that the usefulness of materials is determine.In magnetic particle testing, small particles of iron are applied on the surface of the material after having started a magnetic field.After applying the iron particles, you will see them getting collected at a point which will be interpreted as a leakage if indeed there is one.


The last application but not least in importance is dye solution.


The common method of determining the usefulness of a material nowadays is non-destructive Oil and Gas testing.
