Materials analysis
In addition to classic non-destructive techniques (visual inspections, endoscopy, penetrant testing, magnetic particle testing, radiography, ultrasound, etc.), there are also other non-destructive techniques that permit the analysis of certain properties of metals and welding on site. When there are doubts about the integrity of a system, its operation, the choice of materials used for its construction, or in case damage is established, it is desirable to inspect the installation without shutting it down.
Portable PMI (Positive Material Identification) devices make it possible to conduct analyses using X-ray fluorescence on-site.
The atoms of the workpiece are excited with the help of a built-in X-ray tube (40kV). The electrons in an excited atom on the surface of the workpiece are rearranged. This rearrangement is accompanied by the emission of energy in the form of photons. These are characteristic of the excited atom. The detector can distinguish these photons and quantify the atoms present.
However, this method cannot be used to dose all elements, particularly carbon.
