Nondestructive testing (NDT) plays a critical role in the safety of the many products, transportation systems, and infrastructure used around the world. The importance of NDT in avoiding catastrophic failures cannot be overstated. Beyond the important aspects of safety, though, NDT measurements themselves provide an essential validation of the quality of a product and add economic value to the manufacturing process, as well as help manufacturers avoid the costly effects of a poor-quality product reaching the consumer.
Magnetic particle inspection is a simple NDT method used to detect cracks at the surface of ferromagnetic materials such as steels and nickel-based alloys. The inspection process begins with the magnetization of the component. The surface is then coated with small magnetic particles, which is usually a dry or wet suspension of iron filings.
Dye Penetration Inspection is one of the simplest and oldest Non-Destructive Inspection methods. Also, known as the Liquid penetration test, the Dye penetrant test is widely used to detect surface discontinuities like cracks, fractures, porosity, grinding defects, incomplete fusion, and flaws in joints. This test or inspection method is serving as an aid to finding irregularities in aluminum, cast iron, brass, steel and stainless steel, copper, magnesium, carbides, stellite, ceramics, and even certain plastic materials. So, the dye penetration test is suitable for both ferrous and non-ferrous materials and highly economic as compared to the other non-destructive inspection methods.
AWS MT and PT Endorsement
Non-destructive testing specialists are professionals that use their wide range of technological, reasoning, and creative skills to find imperfections in materials, structures, and equipment. They use older, reliable methods to find and repair these imperfections as well as develop new methods and technology to improve their field.
All though this is an endorsement test, it can be a start towards transitioning into a NDT specialist when trained properly. Through our sister company Advanced NDE Inspection Technologies you can obtain the proper formal hours, training and experience to become a SNT-TC-1A certified Level II inspector that will give you a cutting edge advantage over CWI's in the industry. As a dual certified weld inspector you can make yourself marketable by providing more than one service while on the job-site. No need to bring in costly third party companies!
