Liquid penetrant inspection otherwise called dye penetrant testing or penetrant testing was initially developed in the mid-1940s to discover flaws on material surface. Despite the fact that there are more alternatives in the way the test is carried out, the fundamental standards have not changed throughout the years.
Liquid penetrant inspection is one of the non destructive testing methods which do not damage the samples or any of it parts which is being tested. The test is exceptionally viable in distinguishing porosity, splits, cracks, laps, creases and other imperfections that are open to the surface of the test piece and might be brought on by shrinkage or overload, quenching, impact, fatigue, machining, forging, grinding. Liquid penetrant testing can be utilized effectively on nonporous and genuinely smooth materials, for example, fired ceramics, plastics, glass and metals.
This testing is thus named due to the liquid, called penetrant that is applied on to the sample while it is being tested so that any flaws on the surface becomes more conspicuous. A range of penetrant substances are obtainable and choice is a lot dependant on the requisite sensitivity point of the assessment, tools accessible at the trial site to carry out the test as well as other issues.
PT is a generally quick, simple and cheap method for surface investigation. Expansive amounts of parts or materials can be examined rapidly. Parts of any shape and size can be investigated, in spite of the fact that the limit of tools and the office utilized for testing can create restrictions.
