Positive Material Identification – PMI
Vision Integrity provides Positive Material Identification throughout Western Canada and has several dispatch locations operating 24/7.
Positive Material Identification is a method of nondestructive testing that analyzes the composition of metallic alloys and determining 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 can further determine that the material is in conformance with the applicable specification and determine if the correct electrode was used while welding.
Vision Integrity offers two methods of Positive Material Identification – Florescence (XRF) and Optical Emission Spectrometry (OES).
- Florescence (XRF) is the most common method of Positive Material Identification. The XRF uses a portable device which scans material and identifies its composition. It can be used with the majority of metal material with the exception of carbon and pure carbon steel.
- Optical Emission Spectrometry (OES) is a method that can detect the composition of all materials including carbon steel.
- Can be used on a variety of materials
- Provides accurate analysis of materials
- Can provide immediate results.
- It is a cost-effective method
- Equipment is highly portable
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 can provide testing on sites and at client facilities.
