‘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.
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
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.
