Radiographic Testing (RT)/X-ray Inspection falls under the umbrella of non-destructive testing (NDT) and is a method that examines the target sample by penetrating it with X-rays and in so doing highlights deviations in material density that can signal an imperfection that needs to be addressed.
Radiography uses X-rays and gamma-rays to produce a radiographic image of the target sample, allowing the technician to observe any changes in material thickness, internal and surface defects, and even assembly details (i.e. welds, joints, connectors) to ensure the highest levels of quality and safety in your production.
One of the key benefits of Radiographic Testing (RT) is that it generates a permanent, hard-copy (in the example of x-ray film) record of the scan for a given target sample. In the example of a digital sensor/detector, the record is a digital one that can be stored locally or remotely and does not require the processing and storage needs associated with x-ray films.
What are X-rays?
X-rays are a highly-energetic form of electromagnetic radiation with a wavelength in the range of 1nm to 1 pms, approximately 1000 to 1,000,000 times smaller than the wavelength of light. Due to their being highly energetic, X-rays are able to pass through materials that absorb ordinary visible light.
In general, X-ray inspection systems consist of a radiation safe enclosure, the radiation protection cabinet, containing, in linear alignment, the X-ray tube, and the X-ray detector. A remotely controllable manipulating unit allows the user to position the sample within the beam. The final X-ray image is displayed on a monitor for computerized image processing. In addition, the X-ray system may be outfitted with an electronic program control allowing automated sample inspection. The X-ray image shows object features based on differences in material density.
Part of the X-ray spectrum is absorbed when passing through an object. The thicker or higher in density the object, the more X-rays are absorbed and do not pass through. Those X-rays that pass through the object strike a detector where an X-ray image is created. This image is made up of different shades of gray depending upon the intensity of the incident rays: Parts of the object that are thicker or materials that are higher in density, such as iron, copper, and lead, appear darker than less dense materials such as plastics, paper, or even air.
This film is then processed in a darkroom - much like typical photographic film - and the various degrees of radiation captured by the film are represented as different values of white and black. X-rays not absorbed by the target sample will cause exposure of the radiographic detector. These areas will appear dark. Areas that absorbed higher levels due to higher absorbing or more dense material will appear light.
In this way, regions of your target sample where uniform density has been changed by imperfections, such as porosity, cracks, or misalignment will appear as dark lines, thus making it easier for a skilled technician to detect.
Radiographic Testing (RT) is primarily used in the testing and grading of welds on piping, pressure vessels, storage containers, pipelines, and structural welds.
Really anything that is joined together with a weld that is expected to bear some sort of pressure or load is subject to radiographic testing to ensure the integrity of the welds.
Other tested objects include machined parts, plate metal, or pipe walls (especially where corrosion is a concern).
Ceramics, light metal castings, or additive parts such as those used in the aerospace and automotive industries are also tested via radiography.
Radiographic Testing (RT) can be achieved via X-rays or gamma rays. X-rays are produced via an X-ray tube, while gamma rays are produced by the introduction of a radioactive isotope.
These radiation sources use much higher energy levels than those associated with electromagnetic waves.
Because of the ionizing radiation involved in radiography testing, it is important to make sure proper safety guidelines are communicated and adhered to so as to prevent exposure.
Radiographic Testing (RT) offers several benefits over other forms of NDT. Some of those benefits are:
- a record of the scan that can live either on film or digitally
- ability to look through the whole sample
- a higher level of identification of a defect
- a lower level of skill is required of operators and inspectors
A well-trained radiographer can not only accurately locate a defect with RT, but can also identify its type, size, and location.
When it comes to disadvantages, the obvious is the fact that you are dealing with relatively dangerous materials that can cause adverse, long-term health effects when exposed to radiation.
Additionally, traditional RT solutions, especially film-based ones, require a significant amount of time before one can generate a usable image, thus elongating your production cycle.
This is one reason why so many organizations today are embracing digital detectors which sidestep the processing time associated with traditional x-ray film.
X-Ray Generators
X-ray generators produce X-rays via electron emission in a vacuum. After hitting a target material, X-rays are emitted and directed towards your target sample. In the sample, the x-rays are absorbed or scattered according to the target's material and density. After having passed through your target sample, the photons are then captured by a detector, such as x-ray film or a digital detector.
Digital Conversion
Many organizations today are moving away from traditional film-based radiography to a digital sensor-based solution in an effort to save time, reduce costs, and improve overall NDT performance.
Ultrasonic Testing (UT) and Eddy Current Testing (ECT) are two leading methods of NDT today due to enhanced signal quality, flexible probing options, and the fact they do not involve radioactive materials or dangerous chemicals.
UT relies on ultrasonic waves to probe through your target sample and detect any deviations therein, while with ECT, an electron current runs through your target sample thus generating magnetic fields which highlight material density and thickness deviations.
Both ECT and UT (and particularly phased array ultrasonic testing) are much safer than RT, and in certain applications can be less time-consuming.
Portability is also a hallmark of ECT and UT solutions as they tend to be smaller and easier to operate, thus lending themselves towards use in the field whereas RT is geared more towards laboratory or production line applications. That being said, there are several portable RT solutions today that can be deployed into the field with success.
Computed tomography provides a three-dimensional, spatial image of the object under inspection.
The CT-image shows different materials as different shades of gray (or as different colors). To generate a three-dimensional image, a large number of two-dimensional X-ray images (or slices) are taken around a single axis of rotation (360 °).
These X-ray images are then reformatted as volumetric representations of structures (3D) using a complex reconstruction algorithm.
