This week’s Fun Fact Friday will focus on Liquid Penetrant Testing (LPT) and Examination, one of the Non-Destructive Examination (NDE) inspection services that Encorus Group offers. LPT is used to detect discontinuities that are on the surface of ferromagnetic (materials that are attracted to magnets) or non-ferromagnetic materials. This type of testing is one of the most widely used NDE inspection methods in the construction industry and any other situation where the surface of materials could be subject to discontinuities.
The Liquid Penetration Inspection process involves six main steps:
1.) Pre-cleaning – Any dirt, paint, oil, or loose scale must be removed from the surface of the material
2.) Application of penetrant – Liquid penetrant is applied to the part of the material being tested
3.) Excess penetrant removal – Any excess penetrant is removed from the surface of the part
4.) Application of developer – White developer is applied to the material being tested
5.) Inspection – Visible light with adequate intensity is used for the visible dye penetrant inspection
6.) Post cleaning – After the inspection and recording of results, the material surface should be cleaned
