Positive Material Identification (PMI)

Positive Material Identification (PMI)

PMI, the analysis of a metallic alloy to establish composition by reading the quantities by percentage of its constituent elements. Temperature is often the first and easiest-to-find indication of a developing problem and can be quickly used as a screening technique for situations that will benefit from further analysis. A non-contact IR thermometer allows you to stay a safe distance from the object and get the most accurate readings across a wide range of temperatures, thus,the term noncontact.

NDT AND PWHT Solutions NDT Inspection offers PMI testing services through experienced, trained personnel who can assure quality of service. The material scan and testing services can be performed on-site before the pieces go into the production process. PMI can be utilized on a variety of part sizes – from large complex parts to things as small as the weld fill material on the pieces.
