Radiography Testing (Conventional Methods)
|
|
| |
Radiography is the use of ionizing radiations to view objects in a way that can't be seen otherwise. It is not to be confused with the use of ionizing radiation to change or modify objects; radiography's purpose is strictly for viewing. Industrial radiography has grown out of engineering, and is a major element of nondestructive testing (NDT). It is a method of inspecting materials for hidden flaws by using the ability of short X-rays and Gamma rays to penetrate various materials.

Phased Array Ultrasonic Inspection
|
|
| |
A Method for inspecting a component includes exiting a number of transducers forming an array to produce an ultrasonic transmission beam focused into the component. The array and the component are separated by a standoff. A Number of echo signals are generated using the transducers, and the echo signals are processed in a number of channels.

Ultrasonic Testing
|
|
| |
Ultrasonic testing is often performed on steel and other metals and alloys, though
it can also be used on concrete, wood and composites, albeit with less resolution.
It is a form of non-destructive testing used in many industries including aerospace,
automotive and other transportation sectors.

Automated Ultrasonic Testing (AUT)
|
|
| |
Ultrasonic testing is often performed on steel and other metals and alloys, though it can also be used on concrete, wood and composites, albeit with less resolution. It is a form of non-destructive testing used in many industries including aerospace, automotive and other transportation sectors.

Stress Relieving
|
|
| |
Machining induces stresses in parts. The bigger and more complex the part, the more
the stresses. These stresses can cause distortions in the part long term. If the
parts are clamped in service, then cracking could occur. Also hole locations can
change causing them to go out of tolerance.

|
Magnetic Particle Testing
|
|
| |
The particles that are used for magnetic particle inspection are a key ingredient as they form the indications that alert the inspector to defects. Particles start out as tiny milled (a machining process) pieces of iron or iron oxide. A pigment (somewhat like paint) is bonded to their surfaces to give the particles color.

Dye Penetration Inspection (DPI)
|
|
| |
Dye penetrant inspection also called liquid penetrant inspection (LPI), 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 penetrant may be applied to all non-ferrous materials, but for inspection of ferrous components magnetic-particle inspection is preferred for its subsurface detection capability. LPI is used to detect casting and forging defects, cracks, and leaks in new products, and fatigue cracks on in-service components.

Positive Material Indentification
|
|
| |
Is performed more and more frequently as clients realize the need to assure proper
materials are being utilized in their installations. We utilize the Niton XLP-818
Alloy Analyzer to identify and sort alloy materials using X-ray fluorescence technology.

Time of Flight Diffraction (TOFD)
|
|
| |
Time of Flight Diffraction is a rapidly increasing technique with unique features.High
accuracy defect sizing is combined with high inspection speed. This combination
provides a fast and high quality technique for the inspection of welds and other
critical areas in installations.

Realtime Radiography (RTR)
|
|
| |
Real-time radiography is a well-established method of NDT having applications in automotive, aerospace, pressure vessel, electronic, and munition industries, among others. The use of RTR is increasing due to a reduction in the cost of the equipment and resolution of issues such as the protecting and storing digital images. Since RTR is being used increasingly more, these educational materials were developed by the North Central Collaboration for NDT Education (NCCE) to introduce RTR to NDT technician students.

Remote Field Eddy Current Testing (RFET)
|
|
| |
Remote field testing (RFT) is an electromagnetic method of nondestructive testing whose main application is finding defects in steel pipes and tubes. RFT may also referred to as RFEC (remote field eddy current) or RFET (remote field electromagnetic technique). An RFT probe is moved down the inside of a pipe and is able to detect inside and outside defects with approximately equal sensitivity (although it can not discriminate between the two). Although RFT works in nonferromagnetic materials such as copper and brass, its sister technology eddy-current testing is more effective in these materials.

Eddy Current
|
|

Is particularly well suited for detecting surface cracks but can also be used to
make electrical conductivity and coating thickness measurements. Here a small
surface probe is scanned over the part surface in an attempt to detect a crack.

|
| |
The Internal Rotary Inspection System (IRIS) is a Non-Destructive Ultrasonic Testing
method. This advanced technology is generally used for the measurement of wall thinning
and pitting due to corrosion and erosion of small bore pipes.
