Phased Array Ultrasonic Testing (PAUT)

by admin / On November 9, 2021

Phased Array Ultrasonic Testing (PAUT) is an advanced method of ultrasonic testing that has applications in medical imaging and industrial nondestructive testing. Common applications are to noninvasively examine the heart or to find flaws in manufactured materials such as welds. Single-element (non-phased array) probes, known technically as monolithic probes, emit a beam in a fixed direction. To...

Eddy Current Testing (ECT)

by admin / On November 9, 2021

Eddy currents were identified by James Maxwell in 1864. The term “eddy currents” resulted from the similarity in the movement of these circulating electrical currents to the whirlpool activity of so-called “eddies” in liquids. Eddy currents are defined as circulating electrical currents indirectly induced in an isolated conductor by an alternating magnetic field. The alternating magnetic...

Radiography Testing Film Interpretation (RTFI)

by admin / On November 9, 2021

The examination of the finished radiograph should be made under conditions that favor the best visibility of detail combined with a maximum of comfort and a minimum of fatigue for the observer. To be satisfactory for use in viewing radiographs, an illuminator must fulfill two basic requirements. It must provide light of an intensity that will illuminate the areas of interest in the radiograph to...

ULTRASONIC TESTING (UT)

by admin / On November 9, 2021

Ultrasonic testing instruments have been used in industrial applications for more than sixty years. Since the 1940s, the laws of physics that govern the propagation of high-frequency sound waves through solid materials have been used to detect hidden cracks, voids, porosity, and other internal discontinuities in metals, composites, plastics, and ceramics, as well as to measure thickness and...

Magnetic Particle Testing (MPT)

by admin / On November 9, 2021

Magnetic particle testing is a relatively easy and simple test method that can be used on raw materials, castings, forgings, welds, and finished parts. Magnetic particle testing can be applied to all levels of manufacturing. It can also be used to check processing operations such as heat treatment, machining, and grinding. These manufacturing operations can cause defects by improper processing...

Liquid Penetrant Inspection

by admin / On November 9, 2021

Liquid Penetrant Inspection is a method used to detect surface-breaking discontinuities (e.g., cracks, pits, etc.) in nonporous materials. This method utilizes a dye-containing fluid that penetrates surface discontinuities through capillary action. The trapped penetrant increases the visibility of the discontinuity by providing a visual contrast between the discontinuity and the surrounding...
