A number in parentheses indicates the year of last reapproval. Selecting A Dye Penetrant Method Three steps to narrow down a penetrant method through governing specifications, part composition, and test parts Governing specifications and work procedures often dictate the penetrant method type. Although destructive, dye and pry test is the most efficient and cost-effective means of examining 100% solder connections of BGA and other bottom-terminated SMT packages. Use this app ahead of undertaking the course and you will be a step ahead of your peers, meaning you have more time and headspace to concentrate on the practical elements of the course. Dye penetrant inspection , 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 3 spray cans (aerosol) are provided for this test. Easy online ordering and next-day delivery available with 24/7 expert product support. That being said, dye penetrant testing can provide reliable results in virtually any application as long as its facilitators do it properly. In this technique low viscosity liquids are allowed to penetrate in the surface openings and after penetration, liquid is made to extract out again by means of some developers. Penetrant testing is one step up from visual inspection and offers many advantages, such as speed, large-area coverage and cheapness. 1-1: Liquid Penetrant and Developer Applied to a Casting. Liquid (or dye) Penetrant Inspection (LPI) is used for detecting surface-breaking flaws on any non-absorbent material’s surface. Liquid Penetrant Testing. C—The developer is applied to the weldment. Dye Penetrant Test Module Objectives After the completion of this module, the student will be able to: Explain the basic principles of the Dye Penetrant test. ·Portable dye penetrant inspection kit similar or equivalent to Uresco Model TT-101 spray can system. While both fluorescent and nonfluorescent techniques are available, most aviation applications involve the use of fluorescent penetrants in a bulk process. This non-destructive testing technique, also known as liquid penetrant inspection (LPI), is a cost-effective method used to locate surface breaking flaws such as cracks, porosity, laps, seams and other surface discontinuities. Liquid penetrant examination is one of the most popular Nondestructive Examination (NDE) methods in the industry. Below are the main steps of Liquid Penetrant Inspection: 1. Liquid Penetrant Levels 1 & 2. (HAO) Visible Dye Penetrant Crack Testing Kit Many cracks that extend to the surface of metal parts are completely invisible to the naked eye. Typically the magnaflux light test is performed in a darkened area so the black light illumination can be seen. Identify the different types of penetrant used in the test. Below are the main steps of the Dye Penetrant Inspection process: Pre-cleaning: The roll surface is cleaned to remove any dirt, oil, grease or. It is important to note that, unlike many shops, we test every plate, not a random sampling. Penetrants may be "visible", meaning they can be seen in ambient light, or fluorescent, requiring the use of a "black" light. Where bonding is required, the proper adhesive for the particular gasket material and fluids will be applied. Dye penetrant testing uses special chemistry to reveal surface cracks. TURCO Dy-Chek Penetrant is a red liquid, which penetrates surface discontinuities, even extremely minute ones. This video course presents the steps for performing a color contrast, solvent removable, liquid penetrant inspection with an actual demonstration of the process per MISTRAS 100-PT-001 and ASME Section V, Article 6. Liquid Penetrant inspection is one of the oldest forms of Non Destructive Testing. Pacific Magnetic & Penetrant Co. The operating temperature range for penetrant inspection as specified in ASTM E1417 Standard Practice for Liquid Penetrant Testing is 40°F to 125°F (4°C to 52°C), but how is the penetrant inspection affected at temperatures below 40°F (4°C) and can the inspection process be adjusted to achieve acceptable results?. The shearography tire test system Intact® 1600-2 is designed for the serial testing of retreaded or new passenger car, (light) truck, EM and aircraft tires, as well as for the control of tire carcasses before retreading. Penetrant shall be visible dye, solvent removable type. steps of liquid penetrant testing The exact procedure for liquid penetrant testing can vary from case to case depending on several factors such as the penetrant system being used, the size and material of the component being inspected, the type of discontinuities being expected in the. The fourth step of doing penetrant testing is Step to use Developer spray into the welded for Non-Destructive Testing(NDT) with process Penetrant Testing(PT). This method of inspection is the industry standard for crack detection. 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). by Rich Mylar.
