Positive Material Identification

‘PMI’ is non-destructive testing method known as positive material identification. Positive material identification (or alloy analysis) is the spectral analysis of the elemental  composition of alloys, metals and steel.      
Our technicians perform positive material identification procedures using ARC-MET technology. This process involves inspecting materials to determine exact chemical composition. Our ARC-MET technology also has the capability to determine carbon content, which is something that many other PMI machines do not provide.
PMI is commonly used on old pipes and metal parts to determine exact composition of the material so that welders can safely and effectively work on the metal. Our PMI equipment is portable for easy use in the field. After a reading is taken, the data is analyzed by a computer to determine the exact percentages of different elements. Results are then printed out and given to the customer on site.
