Course Syllabus : Introduction. Liquid Penetrant Inspection Process Surface Preparation: One of the most critical steps of a liquid penetrant inspection is the surface preparation. Chapter 6.0 . A penetrant liquid is applied on the clean surface by spraying, brushing, flooding, dipping, or immersion. It is usually a six-stage process: a) surface cleaning (degreasing etc) b) application of a penetrant liquid (dipping, spray, brush) c) removal of excess penetrant (solvent, water) d) application of developer Extremely portable kit, can be used in remote locations as well. This method is also known as dye penetration testing. Ultraviolet (UV-A) radiation of sufficient intensity (1,000 micro-watts per centimeter squared prevails), together with low ambient light levels . SNT-TC-1A recommended practice. Penetrant Testing, or PT, is a nondestructive. Liquid penetrant testing, as well as any other non-destructive testing, is part of a general or specific assessment of the quality of a casting to be agreed between the purchaser and the manufacturer at the time of acceptance of the order. No other Aerospace NDT School has so much experience.

It will remain till the end of penetration time, which is specified in the standard. Introduction to Liquid Penetrant Examination . Liquid penetrant testing is a nondestructive material examination procedure used to check for deficiencies such as cracks by spreading a thin liquid dye onto the material's surface, followed by the application of a developer. Equipment Familiarization 3. The trapped penetrant increases the visibility of the discontinuity by providing a visual contrast . ASNT Level 3 Liquid Penetrant testing Explain INSPECTION: The inspector will utilize noticeable light with sufficient intensity (100 foot-candles or 1100 lux is normal) for noticeable color penetrant. It originated in the 1890s, where it was used in railroad maintenance shops. The liquid penetrant process is one of the oldest nondestructive testing (NDT) methods. Seeability: the ability of an indication to be seen by an observer under adverse conditions e.g. Penetrant inspection equipment. 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. This method is used to reveal surface discontinuities by bleedout of a coloured or fluorescent dye from the flaw. Non-Destructive Testing (NDT) - Guidance Document: An Introduction to NDT Common Methods 5 This process is called accommodation and gives us very fast continuous focusing adjustment. LPT is based on capillarity or capillary attraction, where a liquid is able to flow into narrow spaces without the assistance of - or even in opposition to - external forces such as gravity.
