Non-Destructive Testing

Critical military, civil and commercial assets are being used beyond their designed life. Navy submarines are planned for 40% life extension, and some strategic bombers may still be flying 100 years after delivery. Most U.S. nuclear power plants have received 50% life extensions. Commercial aircraft, trains and energy infrastructure remain in service far beyond designed intent. Non-Destructive Testing helps ensure the continued operation, safety and reliability of these aging assets.

Non-Destructive Testing (NDT) is a term used for the examination of materials and components in such a way that allows materials to be examined without destruction or damage, ensuring they can be used after testing and insuring the integrity of the component. NDT is a rapidly diminishing skillset in the U.S., but is required to accommodate service life extension.

DeVal Lifecycle Support, a Parts Life, Inc. company, is aggressively investing in our processes and people to extend the nation’s defense, civil and commercial capabilities with Non-Destructive Testing. Parts Life has partnered with the American Institute of Nondestructive Testing as its’ responsible NDT Level III and NDT training provider, so whether you need testing or training of your own personnel, we will get the job done.

Types of Non-Destructive Testing

Visual Testing (VT)

Visual inspection is the most applied NDT method.  Visual examiners recognize surface imperfections and discontinuities that could adversely affect a part or component.  The inspector utilizes knowledge of how a part is manufactured, the function of the human eye, lighting requirements, and precise measuring tools to evaluate materials.  The recognition and measuring features of a component can be enhanced in this method with optical aids and arrangements for direct or remote viewing such as utilizing borescopes, computer-controlled camera systems, and magnification.

Radiographic Testing (RT)

Radiography inspection utilizes radiation (gamma rays or X-rays) directed through a part or component and projected onto film or a digital detection device leaving an internal image to be examined by a qualified Radiographer.  This inspection is sensitive to corrosion, changes in thickness, voids, cracks, and material density changes.

Ultrasonic Testing (UT)

Radiography inspection utilizes radiation (gamma rays or X-rays) directed through a part or component and projected onto film or a digital detection device leaving an internal image to be examined by a qualified Radiographer.  This inspection is sensitive to corrosion, changes in thickness, voids, cracks, and material density changes.

Magnetic Particle Testing (MT)

Magnetic Particle inspection introduces a magnetic field in ferromagnetic material applying iron particles to the surface of the examined part for detecting surface and shallow subsurface discontinuities.  The surface and shallow surface discontinuities affect the flow of the magnetic field within the part causing the particles to gather at locations of flux leakage producing a visible indication of the irregularity on the surface of the part.

(Liquid) Penetrant Testing (PT)

Penetrant inspection is performed with a dye solution, fluorescent or colored.  The dye will penetrate any surface-breaking defects in a non-porous part or component.  Liquid penetrant is used to detect casting, forging, and welding surface defects such as hairline cracks, surface porosity, leaks, and fatigue cracks.

Eddie Current (ET)

Eddy-Current inspection utilizes electromagnetic induction to detect and characterize surface and sub-surface flaws in conductive materials.  This inspection has the ability to detect defects in multi-layer structures and surface coatings.
