Most of the heavy industries that have prospered by implementing NDT technologies such as digital radiography are consistently reaping the benefits of their advanced versions existing in the modern times. Such implementations generally result in improved efficiency, productivity and profit margins.
A variety of products can benefit from digital radiography and its related analog methods, which include radiographic evaluation of metallic, composite and electronic components and structures. Sources of radiation involve X-rays through standard, fractional and micro-focus tubes. Gamma and neutron sources are also used for radiography testing.
Whether an image is produced by a digital radiography panel or computed radiography imaging, the radioactive exposure time and source power is substantially reduced by 30 percent to 50 percent. The benefits are improved production, reduced cost and improved flaw detection.
What is radiography?
Radiographic testing is an important aspect of non destructive testing in Melbourne. In this process, the tested part is placed between a source of radiation and a film or detector. The material density and thickness of the product will attenuate the penetrating radiation through a couple of interaction processes involving scattering and/or absorption. The differences in absorption process are then recorded on a film. In industrial radiography testing, there are several imaging methods applied, these are Film Radiography, Computed Tomography (CT), Real Time Radiography (RTR), Computed Radiography (CR) and Digital Radiography (DR).
There are basically two different radioactive sources available for industrial usage, first is the X-ray and the other is the Gamma-ray. These sources use a higher level of energy with shorter wavelength of electromagnetic waves. As radioactivity is involved in the radiography testing, it is of paramount importance to ensure that the process is applied by strictly maintaining the rules and regulations of the Australian Standards.
The Process Included
Digital radiography professionals typically provide on site complimentary demonstrations and evaluations of the material that has been inspected. Business owners must be prepared for sample replicating the item or structure with all manufacturing defects included in the test.
Benefits of Radiography
- Can inspect assembled components of a material.
- Minimum surface preparation area required.
- Detects both surface and subsurface defects.
- Provides a full proof record of the inspection.
- Verifies any internal flaws in complex structures.
- Isolates internal components.
- Measures the dimensions and angles of a material without sectioning.
- Determines changes in thickness, corrosion, flaws and material density.
Radiography is one of the latest technologies for detecting flaws in a material and is considered to be one of the most efficient NDT methods as well.
