For finding faults on materials' surfaces . Penetrant Testing ( PT) - also known as liquid penetrant inspection (LPI) or dye penetrant testing - is based on the properties of surface wetting and capillary action, which causes a liquid to rise when confined to a small opening. testing, liquid penetrant tests, electromagnetic testing method, neutron radiographic testing, leak testing methods, acoustic emissions, visual inspection and holography. Parts undergoing liquid penetrant inspection are first thoroughly cleaned to be free of oil, grease or other contaminants. Liquid penetrant inspection is a nondestructive test method which does not harm the parts being inspected. 5.2 Penetrant, cleaner and developer shall be of the same brand. ATS offers the following liquid penetrant . This type of testing is carried put on a material in order to detect any flaws in the surface or make the more visible. Liquid penetrant testing has the following disadvantages: Extensive, time-taking pre-cleaning criticalsurface contaminants can mask defects Sensitive to surface-breaking defects only Direct connection to the surface under test necessary Works on relatively non-porous surface materials only No depth sizing Multi-process testing procedure Liquid penetrant testing is a versatile nondestructive test method used for the detection of OPEN TO SURFACE DISCONTINUITIES in a wide variety of solid, non-porous materials. The technique is extensively used for the inspection of all nonporous materials - metals, plastics, or ceramics - and both ferrous and non-ferrous materials. Liquid Penetrant Inspection is basically using a liquid dye to locate surface breaking indications. It was noticed that parts such as axles, crank pins, and couplings that were coated with oil would exude the oil from cracks or other surface openings after first being wiped clean. An examination is administered at the end of the final day of courses. Mechanized liquid or dye penetrant testing (PT) is a non-destructive material testing method in which the capillary forces of find surface cracks or pores are used to make them visible. EQUIPMENT Equipment includes a cleaner, penetrant and developer. Liquid penetrant testing is based on the principle of: a. Polarized sound waves in a liquid. Liquid dye penetrant testing is a common nondestructive testing (NDT) method that is used to detect discontinuities in a variety of engineering materials. Dye penetrant and liquid penetrant inspections are typically carried out in 6 steps: Pre-Cleaning - Parts must go through a pre-cleaning process (etch, alkaline or solvent-cleaning) before the liquid penetrant is applied. The developer acts as a blotter, drawing trapped penetrant out of imperfections open to the surface. Anonymous gFcnQ4go. The basic principle of liquid penetrant testing (PT) is capillary action, which allows the penetrant to enter in the opening of the defect, remain there when the liquid is removed from the material surface, and then re-emerge on the surface on application of a developer, which has a capillary action similar to blotting paper. Liquid penetrant inspection (LPI) is a cost-effective and non-destructive way of locating surface defects such as cracks, porosity, laps, seams, and other surface irregularities. 1.Surface Preparation: One of the most critical steps of a liquid penetrant testing is the surface preparation.
