I. Description
Definition of NDT (Non-Destructive Test)
Nondestructive testing or Non-destructive testing (NDT) is a wide group of analysis techniques used in science and technology industry to evaluate the properties of a material, component or system without causing damage. The terms Nondestructive examination (NDE), Nondestructive inspection (NDI), and Nondestructive evaluation (NDE) are also commonly used to describe this technology. Because NDT does not permanently alter the article being inspected, it is a highly valuable technique that can save both money and time in product evaluation, troubleshooting, and research. Common NDT methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic, remote visual inspection (RVI), eddy-current testing, and low coherence interferometry. NDT is commonly used in forensic engineering, mechanical engineering, petroleum engineering, electrical engineering, civil engineering, systems engineering, aeronautical engineering, medicine, and art. Innovations in the field of nondestructive testing have had a profound impact on medical imaging, including on echocardiography, medical ultrasonography, and digital radiography. NDT Has many Methods, but there are 2 methods of NDT to detect crack that we have to explain : DYE Penetration Definition of DYE Penetrant Dye penetrant inspection (DPI), also called liquid penetrant inspection (LPI) or penetrant testing (PT), is a widely applied and low-cost inspection method used to locate surface-breaking defects in all non-porous materials (metals, plastics, or ceramics). The penetrant may be applied to all non-ferrous materials and ferrous materials, although for ferrous components magnetic-particle inspection is often used instead for its subsurface detection capability. LPI is used to detect casting, forging and welding surface defects such as hairline cracks, surface porosity, leaks in new products, and fatigue cracks on in-service components.

How to applicant the DYE Penetration 1. Clean the surface of the material The test surface is cleaned first so dirt, paint, oil, or grease does not cause indication irrelevant or false. Cleaning methods can use a liquid cleaner (Cleaner / Remover), for redusi alkaline cleaning or vapor degreasing. The final goal of this step is a clean surface where any visible defects and formed into the surface, dry, and free of contamination. 2. Spray penetrant to the area to be inspected Penetrant test is then applied to the surface of the material tested material. Penetrant should be given a "timeout" to seep into any possibilities existing defects (usually 5 to 30 minutes). The wait time depends primarily on the penetrant used, the material is tested and the size of the shortfall sought. As expected, small flaws need more time in penetration. Due to the nature incompatible they must be careful not to apply solvent-based penetrant to the surface to be checked with penetrant has been washed. 3. Clean the remaining penetrant Remnants of penetrant is then removed from the surface. This removal method is controlled by the type of penetrant used. Water-washable, solvent-removable, post-emulsified lipophilic or hydrophilic post-emulsified are common choices. The emulsifier is the highest sensitivity levels, and chemical interaction with oily penetrant to make it removable with water spray. When using a solvent remover and fabric is important not to spray solvent on the surface of the test immediately, as this can remove penetrant from shortages.

4. Application Developer After excess penetrant have been removed white developer applied to the sample. This type of developer provided several, including: non-aqueous wet developers, dry powder, water suspendable, and dissolved in water. Options set by the compatibility penetrant developer (the developer can not use a watersoluble or suspendable in water-washable penetrant), and the inspection conditions. 5. Inspection: Inspectors will use visible light with sufficient intensity (100 foot-candles or 1100 lux typical) for dye penetrant visible. Ultraviolet (UV-A) radiation intensity is adequate (1,000 micro-watts per centimeter squared general), together with low levels of ambient light (less than 2 foot-candles) for fluorescent penetrant inspection. Inspection of the test surface should be done 10 to 30 minutes after the time of development, depending on the type of product.
Advantage and Disadvantage when use the penetrant to detect crack 1. Advantage : o The speed of the test o The low cost 2. Disadvantage : o The detection of only surface flaws o Skin irritation o The inspection should be on a smooth clean surface where excessive penetrant can be removed prior to being developed

Developer Liquid
Function is a solvent removable penetrant for portability, especially for welding operations, and is post emulsifiable for greater resolution of flaw indications. It produces a visible red color contrast, and features outstanding penetrating characteristics is a solvent cleaner/remover for pre-cleaning before nondestructive testing and for removing excess surface penetrant from an inspection area before applying developer during liquid penetrant testing. SKD-S2 solvent-based developer is non-halogenated and ready-to-use. White developing particles suspended in fast-drying solvent produce an opaque white coating for a contrasting background around penetrant indications. It is ideal for machine shops and for welding applications in construction.

To be the bottom of practical dye
Procedure executes the test dye penetrant : Preparation phase 1. prepare penetrant, cleaner and developer liquid 2. Check the place to be for preparation P3K when there is unwanted things happen 3. prepare the board and cloth rags when experimenting Dye penetrant
Implementation phase 1. find objects suspected crack 2. The place objects onto the board 3. The clean up first thing especially around a suspected crack using liquid cleaner and wipe with a cloth rags 4. penetrant spray in the direction of the wind on the surface of the object, wait for it to penetrate 5.
