CRACK TESTING FOR TRUCKS

Crack testing is a method for evaluating the quality or suitability of any material object. Crack testing also helps us study various physical properties of the material under examination, including dimension, hardness, or configuration. Crack tests help us know about the usefulness of the object or material.

There are two types of crack tests commonly observed.

  1. Nondestructive testing: (NDT)

In the nondestructive form of crack testing, the material under examination isn’t wrecked; once tested and approved, it can be reused without any damage. So, the material remains intact in its original state by the end of this type of testing.

  • Destructive crack testing: (DCT)

As the name indicates, in this type of testing, the object under study is wholly damaged or destroyed to understand how well it can tolerate the stress applied. It is good to go if it passes the test; otherwise, weak or poor-quality material-made objects will deteriorate fast.

Usually, in most cases, the nondestructive form of testing is done as there is vast research and developments made in this field, and mechanics and automobile companies also prefer it more than the destructive one.

NON-DESTRUCTIVE EXAMINATION:

This type of testing can also be called nondestructive examination, evaluation, or inspection. These tests could be performed at all stages. That is, we can check the material’s quality and usefulness in its raw form before it is drawn into any object; the examination could be done once it is formed into any object, machine, or device, and the test is still valid during the service period of the material. Various mechanics usually prefer the last one to inspect different parts of the trucks or automobiles while they are still on the road. A brief description of this method is already discussed in the article.

We would jump at the various types of tests involved:

  • VISUAL TESTING (VT):

Visual testing is done with the help of the naked eye. A person examines using his basic senses, particularly his eyes, to form an opinion about the condition based on its appearance. This could be done with the help of a torch or magnifying glass for a more precise, resolved, and magnified image.

  • PENETRANT TESTING (PT):

The penetrant testing is based on capillary action and is done for the object’s outer surface, which means that with the help of this test, the surface defects can be well analyzed.

MAGNETIC PARTICLE TESTING (MPT):

This test also helps one examine the surface well and could be useful for subsurface inspection. In magnetic particle testing, the object is exposed to iron or other material having an affinity towards a magnet. This iron would be attracted towards both poles; if there is any crack on the surface, poles will develop at that site, and you will examine iron being attracted to that region. The only limitation of this test is that the object or material under examination should be ferromagnetic.

RADIOGRAPHIC TESTING (RT):

This test is based on penetration. X-rays and gamma rays have high penetration powers. The material being inspected is placed between the beam source and the radiographic film. The rays will pass through the object or material and hit the film, causing it to turn black. Wherever you find non-uniformity in the blackening of the film, the penetration has been disturbed due to any deformity in the object. This way, the depth of the material could be studied.

Various other tests are also done, including ultrasonic testing (UT), eddy current testing (ECT), thermal infrared testing (TIT), acoustic emission testing (AET) etc., specifying the serviceability of objects based on different aspects.
