Profile: Magna Chek is a full service non-destructive testing source for magnetic particle, radiography, ultrasonics, dye penetrant, eddy current, and hardness. We are an ISO 17025:2005 accredited laboratory. Dye penetrant inspection is a means of locating fine cracks on the surface of parts by allowing a visible or fluorescent dye to accumulate in any such discontinuity to reveal its shape and location. The technique is applicable to virtually any non-porous material. Dye penetrant inspection is a three-step process beginning with the application of a visible or fluorescent dye to the clean, dry surface of the test specimen. In a short time the penetrant is drawn into any surface depressions or voids by capillary action. Magnetic particle testing uses electrically induced magnetic fields in parts made from ferromagnetic materials to detect flux leakage at the site of surface and near-surface discontinuities. The speed and relative simplicity of this technology make it ideal for high volume applications. We are equipped to perform magnetic particle testing on a wide variety of parts in terms of both size and geometry. Testing is provided on a single part or on large lots at rates up to 1,500 parts per hour. Ultrasonic inspection involves the transmission of ultra-high frequency sound waves through the part under scrutiny and evaluating the reflected waves on a time delay oscilloscope. It is useful for detecting sub-surface discontinuities, dimensional measurements (thickness) and analyzing material structure. With both contact and immersion methodologies available, ultrasonic inspection is used for a wide variety of applications. It is frequently used to check weld quality on containment vessels and the integrity of aircraft wing & tail attachments.
