Positive Material Identification – PMI

Positive Material Identification is a method of non-destructive testing that analyzes the composition of metallic alloys and determines the quantities by percentage of its chemical composition. The primary purpose of this method is to verify and identify materials, and if any incorrect material has been used. It determines that the material is in conformance with the applicable specification and detects if the correct electrode was used while welding. Our personnel are trained with both SNT and CGSB XRF NDT Level I or II, as well as our in-house OES training program and can capably detect the chemical composition in a variety of materials.

We offer Florescence (XRF) and Optical Emission Spectrometry (OES).

  • Florescence (XRF) is the most common method of Positive Material Identification. XRF uses a portable device which scans material and identifies its composition. It can be used with most metal material, except for carbon and pure carbon steel.
  • Optical Emission Spectrometry (OES) is a method that can detect the composition of all materials, including carbon steel.

Benefits of Positive Material Identification:

  1. Compatible with a variety of materials
  2. Accurate
  3. Immediate results
  4. Cost-effective
  5. Equipment is highly portable
